Paragon KM Kilns For Making Camping, Hunting, And Kitchen Knives, Blades, Cutters, Dies, Swords, Tools, Model Parts, And Gun Components, Annealing, Heat-Treating, And Glass Work.

Paragon KM kilns are generally used for making camping, hunting, kitchen, and pocket knives, and annealing, hardening, heat treating, and tempering blades, cutters, dies, scissors, swords, tools, architectural features, engineering components, and model parts, although they have other applications. They're 1290°C furnaces with digital programmers, in Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise. Learn about Paragon KM ovens on this page.


There are five standard versions, 140mm wide internally: the KM14, KM18, KM24, KM36, and KM45 with drop-down doors, firebrick interiors, and Sentry Xpress 3-Key programmers.

There are five standard XL versions, 279mm wide internally: the KM9 XL, KM14 XL, KM18 XL, KM24 XL, and KM36 XL with drop-down doors, firebrick interiors, and Sentry 12-Key programmers.

There are five PRO versions, 165mm wide internally: the KM9 PRO, KM14 PRO, KM18 PRO, KM24 PRO, and KM36 PRO with stainless-steel spring-assisted guillotine doors, rigidised ceramic-fibre interiors, high-power fast-heat embedded elements, zoned temperature control, and touch-screen Sentinel SmartTouch programmers.

There are six XL PRO versions, 337mm wide internally: the KM9 XL PRO, KM14 XL PRO, KM18 XL PRO, KM24 XL PRO, KM36 XL PRO, and KM45 XL PRO with stainless-steel spring-assisted guillotine doors, rigidised ceramic-fibre interiors, high-power fast-heat embedded elements, zoned temperature control, and touch-screen Sentinel SmartTouch programmers.

Paragon's kiln names often include numbers or letters to represent internal dimensions or features. The number, as in KM24, is the approximate interior depth in inches. The XL versions are about twice as wide as the standard. In the US, the XL versions are sometimes called Double-Barrel or just D, as in KM24D.


Prices here are transparent: they're for UK-EU voltage, CE marked, CL CSA approved, and TUV tested kilns, and include comprehensive instructions, a heat-treating guide, UK VAT, and free continuing support from a top-tier international distributor. So you can start work straight away.

Paragon KM knife-making kilns are favoured by knife-makers all over the world. Their innovative features and contemporary design puts them way ahead of other blade furnaces. Every version is described in detail below so, although there's a comparative table and photos, I recommend that you set aside some time and read about them.

KM NAMING OPTIONAL READING

Paragon KM Kilns For Making Camping, Hunting, And Kitchen Knives, Blades, Cutters, Dies, Swords, Tools, Model Parts, And Gun Components, Annealing, Heat-Treating, And Glass Work.

All Paragon kilns are modified as new, or better, ideas become part of the current design. So I should clarify how things have changed.

Paragon uses the suffix Xpress if the kiln has a Sentry Xpress 3-key programmer. For example, the KM24 Xpress. However, for most other kilns it's used inconsistently, or not at all: so rely on the descriptions here.

In 2017, Paragon gave the programmers an easier-to-read tilt. D, which meant depth, was replaced with T, which means tilted. So, for example, a KM24D became a KM24T, although KM24 would have been simpler since all the D versions have been discontinued. And, D and T are used elsewhere for digital, door, and top ...

In 2018, Paragon introduced the XL versions. In the US, Paragon called them Double-Barrel, although double-barrel usually means two separate barrels, not one barrel which is twice as wide.

In 2018, Paragon added solid-state electronic relays which provide complete electrical isolation between their input and output. They don't have moving parts or mechanical contacts so they're silent, have a very long life, and are ultra-reliable.

In 2019, Paragon introduced the PRO and XL PRO versions, with stainless-steel spring-assisted guillotine doors, rigidised ceramic-fibre interiors, high-power fast-heat embedded elements, zoned temperature control, and touch-screen Sentinel SmartTouch programmers.

Later in 2019, Paragon dropped the suffixes T and Double-Barrel. Double-Barrel was replaced with D, now meaning double not depth, so a KM24T Double-Barrel became a KM24D. However, to impose some consistency, we use XL instead of D, as in KM24 XL, in line with other Paragon kilns such as the BlueBird XL and the Caldera XL.

Why Is A Paragon KM Kiln The Best Mix Of Technologies At The Best Price?

Paragon KM furnaces are 1290°C, rectangular, front-opening, table-top kilns, with ramp-hold digital programmers. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise. Customised kilns are made to order so can't be returned if the colour isn't exactly as in the photos.


The KM14, KM18, KM24, KM36, and KM45 normally have Sentry Xpress 3-key programmers which allow you to create, edit, and save your own ramp-hold sequences: up to twenty-five, each one with up to twenty segments. You can upgrade to an enhanced Sentry 12-key or an advanced touch-screen Sentinel SmartTouch.

The KM9 XL, KM14 XL, KM18 XL, KM24 XL, and KM36 XL normally have enhanced Sentry 12-key programmers which allow you to create, edit, and save your own ramp-hold sequences: up to thirty-five, each one with up to twenty segments. Features include automatic control over hardware options: an electric kiln vent, a gas injection system, and a USB computer interface. You can upgrade to an advanced touch-screen Sentinel SmartTouch.

The PRO and XL PRO versions normally have advanced touch-screen Sentinel SmartTouch programmers. Features include those of the Sentry 12-key and real time displays of voltage and current, a novice mode with prompts, firing sequences presented graphically, and wifi updates: so a functional upgrade not just a design preference. However, if you don't want a Sentinel SmartTouch, you can choose a Sentry 12-key.

When the programmer turns the elements off at, for example, 700°C, residual heat will continue to increase the temperature briefly. A small kiln might overshoot to 715°C before dropping back down. A software modification slows down the heating just before the target temperature, reducing any overshoot and improving the accuracy.


The PRO and XL PRO versions have insulated stainless-steel guillotine doors and are spring-assisted on both sides for easy one-handed opening, with the hot side facing away from you.

The PRO and XL PRO versions have flat wave-shaped elements embedded in the 50mm thick ceramic-fibre sides so they heat very quickly. For durability, the surface of the fibre is rigidised so, unlike firebricks, it's dust free.

The silent long-life solid-state relays are mounted on aluminium heat-sinks. They have no moving parts and the input and output are electrically and mechanically isolated.

They all have special-limit nickel-chromium K-type thermocouples. These respond quickly to changes in temperature, resist corrosion, and have an error margin of less than 0.4% instead of the typical 0.8%. However, for continual high-temperature high-precision professional use, these can be upgraded to platinum-rhodium S-types.


Generally, kiln shelves aren't used for heat-treating and making knives. However, for knife-making, there's an optional kit: four blade holders with pins, eight holder supports, and hot gloves. For ceramics, glass, and metal clays there are several optional shelf kits: never fire things directly on the floor of the firing chamber.


As a general comment, some tabletop kilns are too heavy or too large for a regular table or worktop. If you can't find a strong one locally, Paragon makes a tough steel table, 768mm x 768mm x 718mm high with lockable casters and two shelves for your accessories and greenware.
Of course, although some kilns come with legs or tables, you don't have to use them. You could stand the kiln on a worktop if the height is more convenient. However, you will need to put the kiln on 50mm thick firebricks so that air can circulate.


For help, or in the unlikely event of a fault, you can mail or call an engineer in the UK. However, checks, adjustments, and repairs are simple, needing little more than a PosiDriv screwdriver: watch the on-line videos using the watch-videos link or read the help pages using use the help link, both below the menu bar near the top of any page. Alternatively, we can service the kiln in our workshop at Cherry Heaven.

APPLICATIONS

OPTIONAL READING

Over the years, I've sold a lot of KM kilns. Many were used to heat-treat blades, and camping, hunting, kitchen, and pocket knives. However, some architectural, artwork, or engineering pieces made from ceramics, glass, or metal strips or tubes needed annealing, firing, fusing, heat-treating, melting, moulding, or sintering.

The ceramic tubes were used for high-power resistors, the glass tubes for an art installation, and the metal tubes for a concept-car project. A large cubic or cylindrical kiln might be wide enough but is far too high: it wastes energy, takes much longer to heat and cool, needs more floor or worktop space. and is a lot more expensive.

A shelf resists thermal fracture, provides a smooth stable work surface, protects the floor of the kiln's interior from glass accidents, and helps to even out any small temperature deviations during annealing, enamelling, firing, and fusing as the elements turn on and off. Although the KM kilns have recommended small shelves for occasional work, we have various sizes of ceramic-fibre boards, 25mm, 30mm, or 50mm thck. You can cut the sheets yourself, but call or mail for prices.


You can use these kilns for silver clays, annealing beads and glass, bronze and copper clays, firing bone china, ceramics, earthenware, porcelain, pottery, and stoneware, china painting, crystalline gazes, applying decals, dental work, dichroic glasses, dolls, enamelling, fire polishing, glass art, fusing, moulding, sagging, and slumping glass, heat treating, knife-making, laboratory testing, lampwork, lost-wax casting, low-fire ceramics, making jewellery, melting gold and silver, forming gun and model parts, pâte de verre, raku, sintering gold and silver clays, staining glass, hardening and tempering blades, cutters, dies, and tools, and many other materials and processes.

Although smaller kilns are more economic for jewellery-making, you can still use most popular small-scale materials such as Accent Gold, Art Clay metal clays, BullsEye glasses, dichroic glasses, enamels, GlasClay, Image Transfer Solution, Metal Clay Veneer, PMC silver clay, PROmetheus bronze clay, PROCopper clay, and SilverEtch.
And there's an increasingly diverse range of other metal clays, such as Cinter, Clay Mania, Creative, Goldie, Hadar Jacobson, Metal Adventures, Meteor, Noble, and PMC Sterling.

You can make architectural features, beads, bowls, bracelets, brooches, candle holders, ceramic art, chandelier components, decorations, figurines, fingerprint keepsakes, glass-art, glass panels, jewellery, knives, lampshades, miniatures, gun and model parts, mugs, necklaces, ornaments, pendants, plates, porcelain beads, souvenirs, stained-glass designs, tableware, tiaras, tiles, tools, and vases, as unique hand-crafted pieces or repeatable stock for sale.


They're ideal for your arts centre, college, course venue, shared craft units, dental lab, engineering works, glass works, home hobby, knife studio, machine shop, medical laboratory, metal-work business, technical facility, or university.

IS A PARAGON KM KILN THE BEST CHOICE?

Is A Paragon KM Kiln Going To Be The Best Long Term Choice?

Paragon KM kilns are the right shape to heat-treat blades, accurately and economically: it would be wasteful to heat a wider or taller interior. However, if you think that a smaller or larger kiln might be more useful, here are some suggestions:


Bead-annealing kilns generally have a maximum temperature of 650°C, such as the BlueBird Series. However, other kilns have bead doors: the small Caldera-B and SC2B, the medium Xpress-E12B, and the larger Fusion-14B.

Glass kilns generally have a maximum temperature of 925°C. For these, look at the F Series, Fusion:CS Series, GL Series, or Pearl Series. These are not hot enough for ceramics.

Jewellery kilns generally have a maximum temperature of 1095°C. For these, look at the small SC Series or the medium Xpress Series. The SC series are not hot enough for ceramics.

Ceramics kilns generally have a maximum temperature of 1290°C. For these, look at the small Caldera Series and FireFly Series, medium Xpress Series, or large Janus Series, PMT Series, and TNF Series. These can also be used for glass work.

Heat-treating kilns generally have a maximum temperature of 1290°C. For these, look at the HT Series and PMT Series. Although they look similar, the HT has a bottom-hinged door and the PMT has a side-hinged door.

Knife-making kilns generally have a maximum temperature of 1290°C. The KM Series are made for depth rather than width. You can choose a guillotine, drop-down, or a side-hinged door.

The W Series have a top vent so are usually used for jewellery moulds and lost-wax burnout. For lost wax casting there are optional metal grids and wax trays. The small SC Series and most of the medium Xpress Series also have top vents.

A NOTE ABOUT FIREBRICK KILNS OPTIONAL READING

Paragon KM Kilns For Making Camping, Hunting, And Kitchen Knives, Blades, Cutters, Dies, Swords, Tools, Model Parts, And Gun Components, Annealing, Heat-Treating, And Glass Work.

Fireplace, forge, and furnace bricks are hard, tough, and solid. Often, they're not cemented together so, if you have a conventional fireplace at home, remove a brick and you'll notice a few hair line cracks and missing corners, chips, and flakes. Some might have cracked in half, but they still function. To retain heat, the bricks are dense and heavy.

A kiln made using these would be very heavy and need a much larger and stronger metal frame and case. They're hard to cut, so making joints and element grooves, and using element pins, is almost impossible. The kiln would be more expensive to make and transport and, once in your studio, would be hard to move: try lifting your night-storage heater. And a 500mm square kiln lid made from 24 bricks would probably collapse.


Kiln bricks look like fine sponge. They're light, fragile, and are made to insulate, not store heat. They heat and cool quickly so that the programmer can control the temperature. They can be cut, drilled, and made with joints and element grooves.

Unlike a fireplace, forge, or furnace, kilns are usually used for ramp-hold firings with multiple segments, so are continually cycling through heating and cooling. As the temperature changes, the bricks expand and contract and soon develop fine cracks. If the interior of a kiln expands by about 3mm per 500mm, then contracts, then expands ... something has to give.

Even assembly stresses or small changes in temperature can cause fine cracks during manufacture, factory testing, shipping, or first use. These are normal and won't affect the functionality. And the kiln won't fall apart because the bricks are held together within a metal frame. To quote Paragon: hairline cracks can appear at any time: even in a new kiln. Replacing a whole set of bricks is pointless: the new set will probably develop a tiny crack immediately.

We had an Xpress E12 in the studio for years. The first hairline crack appeared on day one and we ended up with about six, although it worked perfectly. We do have kiln-repair cement if a piece breaks away but you can't squeeze it into a hairline crack. Brushing it on might be a minimal cosmetic improvement but such a thin layer won't repair the brick.

After looking at each kiln in detail, I'll introduce the appropriate accessories, options, and upgrades.

THE PARAGON KM9 XL KILN

The Paragon KM9 XL Furnace For Making Camping, Hunting, And Kitchen Knives, Blades, Cutters, Dies, Swords, Tools, Model Parts, And Gun Components, Heat-Treating, And Glass Work.

Paragon KM9 XL D Double-Barrel Kiln With A Sentry Programmer For Knife-Making And Heat-Treating. Paragon KM9 XL D Double-Barrel Oven With A Sentry Programmer For Knife-Making And Heat-Treating. Paragon Blue Or Customised Berry, Black, Jade, Navy, Pink, Purple, Or Turquoise. Orton-Paragon Sentry Controller.

The Paragon KM9 XL is a 1290°C, rectangular, plug-in, front-opening, table-top, firebrick furnace, with a ramp-hold Sentry 12-key digital programmer. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise.


Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 9 means that the inside is about 9 inches deep. In the US, the KM9 XL is called a KM9 Double-Barrel or just a KM9D.


The UK-EU kiln is rated at 230V-240V 1800W, so can use a regular mains socket. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 559mm x 597mm x 457mm high. The standard drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle, although you can choose a side-hinged door. The shipping weight, including the crate, is about 64kg.

The firing chamber measures 279mm x 229mm x 108mm high and heats from the top and both sides with the elements in dropped recessed grooves in the 76mm thick bricks. The kiln has a silent long-life solid-state relay mounted on an aluminium heat-sink and a long-life nickel-chromium K-type thermocouple.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.


The options, upgrades, and accessories for this kiln are in the on-line shop:

List. a berry, blue, jade, navy, pink, purple, or turquoise respray: normally black
List. a side-hinged door: normally a drop-down: factory fitted
List. a programmer upgrade: Sentry 12-key to a Sentinel SmartTouch: more useful features: factory fitted
List. a programmer upgrade from ramp-hold to cone-fire and ramp-hold: up to cone 10: factory fitted
List. a gas injection flow meter with a controlling solenoid: needs 12-key or touch: factory fitted
List. an electric kiln vent: factory fitted
List. an auxiliary power output for automatic vent control: needs 12-key or touch: factory fitted
List. a USB computer interface: needs 12-key or touch: factory fitted
List. a long-life S-type platinum-rhodium thermocouple upgrade: factory fitted
List. a knife-making kit: four blade holders with removable pins, eight holder-supports, and hot gloves
List. shelf kits and shelf paper
List. ceramic fibre cloth
List. ceramic block
List. HEPA dust mask
List. clear protective glasses
List. glare-resistant glasses
List. heat-resistant gloves

And finally, my opinion:

The KM9 XL is a robust, practical, high-temperature, fully-programmable, double-width kiln, ideal for a blade workshop or an engineering facility making camping knives, hunting knives, kitchen knives, and pocket knives, and annealing, hardening, heat-treating, and tempering blades, cutters, dies, tools, and metal parts. And you can work with ceramics and glass within the kiln's size limits.

The kiln normally has a Sentry 12-key Programmer, although you can upgrade to a touch-screen Sentinel SmartTouch. Both have advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The standard drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

The optional side-hinged door has a lever door-latch and an external safety-switch box mounted above the hinge: not such a tidy design.

Just be sure that 229mm is deep enough and that one of the KM14 series might be better: a KM14, a KM14 XL or, for precision work, a two-zone KM14 PRO or a two-zone KM14 XL PRO, all described below.

THE PARAGON KM9 XL: KILN FURNITURE

Shelf Kits For The Paragon KM9 XL.

Experienced knife makers often make their own blade holders, holder-supports, and accessories, so there's no included kit. However, there's a getting-started recommended kit, not included in the price: four blade holders with removable pins, eight holder-supports, and a pair of heat-resistant gloves.

For annealing beads and glass, firing ceramics and porcelain, fusing dichroics, enamelling, heat treating, lampworking, or sintering metal clays, there's a recommended shelf kit, not included in the price: one durable 254mm x 203mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of glass separator.

The Paragon KM9 XL PRO is a 1290°C, rectangular, wired-in, front-opening, table-top, firebrick furnace, with a ramp-hold touch-screen Sentinel SmartTouch digital programmer. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise.


Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 9 means that the inside is about 9 inches deep. In the US, the KM9 XL PRO is called a KM9 Double-Barrel PRO or just a KM9D PRO.


The UK-EU kiln is rated at 230V-240V 3300W, so needs a 14A minimum wired-in power supply. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 521mm x 584mm x 457mm high. The stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening with the hot side facing away from you. However, you can choose a counterbalanced drop-down door. The shipping weight, including the crate, is about 58kg.

The firing chamber measures 337mm x 229mm x 133mm high and heats from both sides with the elements embedded in the surface of the 64mm thick rigidised fibre. The kiln has a silent long-life solid-state relay mounted on an aluminium heat-sink and a long-life nickel-chromium K-type thermocouple.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.


The options, upgrades, and accessories for this kiln are in the on-line shop:

List. a berry, blue, jade, navy, pink, purple, or turquoise respray: normally black
List. a drop-down door: normally a guillotine: factory fitted
List. a programmer upgrade from ramp-hold to cone-fire and ramp-hold: up to cone 10: factory fitted

List. shelf kits and shelf paper
List. ceramic fibre cloth
List. ceramic block
List. HEPA dust mask
List. clear protective glasses
List. glare-resistant glasses
List. heat-resistant gloves

And finally, my opinion:

The KM9 XL PRO is a 5-star luxury design classic, made for precision work that needs reliable and stable temperatures. It's a robust, practical, high-temperature, fully-programmable, double-width furnace.

It's ideal for a blade workshop or an engineering facility making camping knives, hunting knives, kitchen knives, and pocket knives, and annealing, hardening, heat-treating, and tempering blades, cutters, dies, tools, and metal parts. And you can work with ceramics and glass within the kiln's size limits.

The touch-screen Sentinel SmartTouch digital programmer has advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The rigidised ceramic-fibre firing chamber has closely-spaced, wave-shaped, embedded elements, giving a more even heat distribution than conventional coiled elements in firebrick. It heats quickly and has a fast response time during the hold segments of the firing sequence, minimising any temperature fluctuations as the elements turn on and off.

The insulated stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening, with the hot side facing away from you. It actuates a switch that cuts off the power to the elements when the kiln is opened.

The optional drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

Just be sure that 914mm is deep enough and that one of the KM14 series might be better: a KM14, a KM14 XL or, for precision work, a two-zone KM14 PRO or a two-zone KM14 XL PRO, all described below.

Shelf Kits For The Paragon KM18.

Experienced knife makers often make their own blade holders, holder-supports, and accessories, so there's no included kit. However, there's a getting-started recommended kit, not included in the price: four blade holders with removable pins, eight holder-supports, and a pair of heat-resistant gloves.

For annealing beads and glass, firing ceramics and porcelain, fusing dichroics, enamelling, heat treating, lampworking, or sintering metal clays, there's a recommended shelf kit, not included in the price: one durable 125mm x 125mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of glass separator.

Paragon Blue Or Customised Berry, Black, Jade, Navy, Pink, Purple, Or Turquoise. Orton-Paragon Sentry Digital Controller.

The Paragon KM18 XL is a 1290°C, rectangular, plug-in, front-opening, table-top, firebrick oven, with a ramp-hold Sentry 12-key digital programmer. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise.


Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 18 means that the inside is about 18 inches deep. In the US, the KM18 XL is called a KM18 Double-Barrel or just a KM18D.


The UK-EU kiln is rated at 230V-240V 3073W, so can use a regular mains socket. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 508mm x 813mm x 457mm high. The standard drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The shipping weight, including the crate, is about 85kg.

The firing chamber measures 279mm x 457mm x 108mm high and heats from the top and both sides with the elements in dropped recessed grooves in the 76mm thick bricks. The kiln has a silent long-life solid-state relay mounted on an aluminium heat-sink and a long-life nickel-chromium K-type thermocouple.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.


The options, upgrades, and accessories for this kiln are in the on-line shop:

List. a berry, blue, jade, navy, pink, purple, or turquoise respray: normally black

And you can work with ceramics and glass within the kiln's size limits.

The kiln normally has a Sentry 12-key Programmer, although you can upgrade to a touch-screen Sentinel SmartTouch. Both have advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The standard drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 18 means that the inside is about 18 inches deep.


The UK-EU kiln is rated at 230V-240V 5400W, so it needs a 14A minimum wired-in power supply. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 368mm x 813mm x 457mm high. The standard guillotine door is spring-assisted on both sides for easy one-handed opening, although you can choose a counterbalanced drop-down door. The shipping weight, including the crate, is about 74kg.

The firing chamber measures 165mm x 457mm x 133mm high and heats from both sides with the elements embedded in the surface of the 64mm thick rigidised fibre. The kiln has three silent long-life solid-state relays mounted on aluminium heat-sinks and three long-life nickel-chromium K-type thermocouples.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.

And finally, my opinion:

The KM18 PRO is a 5-star luxury design classic, made for precision work that needs reliable and stable temperatures. It's a robust, practical, high-temperature, fully-programmable, double-width furnace.

It's ideal for a blade workshop or an engineering facility making camping knives, hunting knives, kitchen knives, and pocket knives, and annealing, hardening, heat-treating, and tempering blades, cutters, dies, tools, architectural features, engineering components, and metal parts. And you can work with ceramics and glass within the kiln's size limits.

The touch-screen Sentinel SmartTouch digital programmer has advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The rigidised ceramic-fibre firing chamber has closely-spaced, wave-shaped, embedded elements, giving a more even heat distribution than conventional coiled elements in firebrick. It heats quickly and has a fast response time during the hold segments of the firing sequence, minimising any temperature fluctuations as the elements turn on and off.

There are three separated thermocouples in the top, so the programmer can use its 3-zone feature to prevent temperature gradients and maintain accurate and consistent temperatures throughout the kiln.

The insulated stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening, with the hot side facing away from you. It actuates a switch that cuts off the power to the elements when the kiln is opened.

The optional drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

And finally, my opinion:

The KM24 PRO is a 5-star luxury design classic, made for precision work that needs reliable and stable temperatures. It's a robust, practical, high-temperature, fully-programmable, double-width furnace.

It's ideal for a blade workshop or an engineering facility making camping knives, hunting knives, kitchen knives, and pocket knives, and annealing, hardening, heat-treating, and tempering blades, cutters, dies, tools, architectural features, engineering components, and metal parts. And you can work with ceramics and glass within the kiln's size limits.

The touch-screen Sentinel SmartTouch digital programmer has advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The rigidised ceramic-fibre firing chamber has closely-spaced, wave-shaped, embedded elements, giving a more even heat distribution than conventional coiled elements in firebrick. It heats quickly and has a fast response time during the hold segments of the firing sequence, minimising any temperature fluctuations as the elements turn on and off.

There are three separated thermocouples in the top, so the programmer can use its 3-zone feature to prevent temperature gradients and maintain accurate and consistent temperatures throughout the kiln.

The insulated stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening, with the hot side facing away from you. It actuates a switch that cuts off the power to the elements when the kiln is opened.

The optional drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

Just be sure that 914mm is deep enough and that one of the KM36 series might be better: a KM36, a KM36 XL or, for precision work, a three-zone KM36 PRO or a three-zone KM36 XL PRO, all described below.

Shelf Kits For The Paragon KM24 PRO.

Experienced knife makers often make their own blade holders, holder-supports, and accessories, so there's no included kit. However, there's a getting-started recommended kit, not included in the price: four blade holders with removable pins, eight holder-supports, and a pair of heat-resistant gloves.

For annealing beads and glass, firing ceramics and porcelain, fusing dichroics, enamelling, heat treating, lampworking, or sintering metal clays, there's a recommended shelf kit, not included in the price: one durable 178mm x 178mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of glass separator. This kiln has room for three shelves, one behind the other.

Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 24 means that the inside is about 24 inches deep. In the US, the KM24 XL PRO is called a KM24 Double-Barrel PRO or just a KM24D PRO.


The UK-EU kiln is rated at 230V-240V 9680W, so needs a 41A minimum wired-in power supply. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 521mm x 965mm x 457mm high. The stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening with the hot side facing away from you. However, you can choose a counterbalanced drop-down door. The shipping weight, including the crate, is about 70kg.

The firing chamber measures 337mm x 610mm x 133mm high and heats from both sides with the elements embedded in the surface of the 64mm thick rigidised fibre. The kiln has three silent long-life solid-state relays mounted on aluminium heat-sinks and three long-life nickel-chromium K-type thermocouples.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.

The Paragon KM45 XL PRO is a 1290°C, rectangular, wired-in, front-opening, table-top, firebrick furnace, with a ramp-hold touch-screen Sentinel SmartTouch digital programmer. Choose Paragon black or customised berry, blue, jade, navy, pink, purple, or turquoise.


Paragon's kiln names often use a suffixed number to represent one or more of the internal dimensions in inches. For this kiln, 45 means that the inside is about 45 inches deep. In the US, the KM45 XL PRO is called a KM45 Double-Barrel PRO or just a KM45D PRO.


The UK-EU kiln is rated at 230V-240V 16940W, so needs a 71A minimum wired-in power supply. To comply with EU safety regulations, it's fitted with a switch that cuts off the power to the elements when the kiln is opened: an important safety feature. However, never get careless: kilns are very hot and connected to the mains.

The external dimensions are 521mm x 1549mm x 457mm high. The stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening with the hot side facing away from you. However, you can choose a counterbalanced drop-down door. The shipping weight, including the crate, is about 132kg.

The firing chamber measures 337mm x 1143mm x 133mm high and heats from both sides with the elements embedded in the surface of the 64mm thick rigidised fibre. The kiln has four silent long-life solid-state relays mounted on aluminium heat-sinks and three long-life nickel-chromium K-type thermocouples.

The programmer's electronic display prompts for heating rates, target temperatures, hold times, and cooling rates, making it easy to set up and re-use accurate heating, holding, and cooling sequences. An optional cone-fire mode, up to cone 10, will simplify any work with ceramics.


The options, upgrades, and accessories for this kiln are in the on-line shop:

And finally, my opinion:

The KM45 XL PRO is a 5-star luxury design classic, made for precision work that needs reliable and stable temperatures. It's a robust, practical, high-temperature, fully-programmable, double-width furnace.

It's ideal for a blade workshop or a technical facility making chef's knives, long blades, ceremonial swords, rapiers, architectural features, engineering components, and gun parts, and annealing, hardening, heat-treating, and tempering blades, cutters, dies, and tools. And you can work with ceramics and glass within the kiln's size limits.

The touch-screen Sentinel SmartTouch digital programmer has advanced and time-saving features, and control over optional extras: an electric kiln vent, a gas injection system, and a USB computer interface.

The rigidised ceramic-fibre firing chamber has closely-spaced, wave-shaped, embedded elements, giving a more even heat distribution than conventional coiled elements in firebrick. It heats quickly and has a fast response time during the hold segments of the firing sequence, minimising any temperature fluctuations as the elements turn on and off.

There are three separated thermocouples in the top, so the programmer can use its 3-zone feature to prevent temperature gradients and maintain accurate and consistent temperatures throughout the kiln.

The insulated stainless-steel guillotine door is spring-assisted on both sides for easy one-handed opening, with the hot side facing away from you. It actuates a switch that cuts off the power to the elements when the kiln is opened.

The optional drop-down door is hinged at the bottom and kept closed by the stay-cool counterbalanced handle. The internal safety switch is activated by the hinge.

Shelf Kits For The Paragon KM45 XL PRO.

Experienced knife makers often make their own blade holders, holder-supports, and accessories, so there's no included kit. However, there's a getting-started recommended kit, not included in the price: four blade holders with removable pins, eight holder-supports, and a pair of heat-resistant gloves.

For annealing beads and glass, firing ceramics and porcelain, fusing dichroics, enamelling, heat treating, lampworking, or sintering metal clays, there's a recommended shelf kit, not included in the price: one durable 305mm x 305mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of glass separator.

THE PARAGON SENTRY XPRESS 3-KEY VERSION 4.0 AND VERSION 5.0 DIGITAL PROGRAMMERs
Orton-Paragon Sentry Xpress 4.0 Programmer. Orton-Paragon Sentry Xpress 4.0 Programmer PCB. Orton-Paragon Sentry 2.0 Programmer. Bartlett-Paragon Touch-Screen Sentinel SmartTouch Controller.

The Orton-Paragon Sentry Xpress 3-Key 4.0 and Sentry Xpress 3-Key 5.0 Digital Controllers.

Before February 2019, Paragon used three programmers: a Sentry Xpress 3-key 4.0 or a Sentry 12-key 2.0 developed by the Orton Ceramic Foundation and Paragon, or a touch-screen Sentinel SmartTouch programmer developed by Bartlett and Paragon.

In February 2019, two were modified, leading to the Sentry Xpress 3-key 5.0 and the Sentry 12-key 3.0. The modifications had little effect on the basic functionality so the 5.0 can be a direct replacement for the 4.0, and the 3.0 for the 2.0.

All three are made as ramp-hold, or cone-fire ramp-hold. Your kiln will have the appropriate programmer although, if it has a Sentry Xpress 5.0 ramp-hold, you can upgrade it to cone-fire ramp-hold. If the kiln's front panel is large enough, you can upgrade from a Sentry Xpress 3-key to a Sentry 12-key or a Sentinel SmartTouch.

Generally, programmers for annealing beads, enamelling, glass fusing, jewellery, knife-making, lampwork, and metal clays have one firing mode: ramp-hold. And programmers for ceramics, earthenware, porcelain, and stoneware have two firing modes: cone-fire and ramp-hold.


Unlike calculators, programmers aren't made 10 million at a time. Although they look like simple circuit boards, they include sophisticated feature-rich embedded software that has taken years to develop and refine.


The Paragon Sentry Xpress 3-key 5.0 programmer allows you to set up to twenty five ramp-hold firing sequences, each one with up to twenty heating, holding, or cooling segments. You can choose the heating and cooling rates, target temperatures, and hold times, save the sequences, and re-use or over-write them.

It's easy to use: far easier than a central heating programmer. Here's a Cherry Heaven TV programme about setting a simple ramp-hold sequence on a 4.0 programmer. The ramp is the part where the temperature increases until it reaches the target temperature: the hold is the part where the temperature stays the same. UK-EU programmers will be in degrees Celsius.

The programmer runs a sequence that you have set, or one that's in its memory from a previous firing. A sequence usually has a mix of ramp and hold segments, for example: it could heat to 800°C at full speed then hold for 30 minutes. When the sequence ends, the programmer beeps, and the kiln cools in it's own time.

A ramp segment of a sequence can control the rate of heating or cooling, for example: the kiln could heat up at 200°C per hour from 200°C to 800°C, which would take three hours. Or, the kiln could cool down at 100°C per hour from 600°C to 200°C, which would take four hours.

The heating rate cannot exceed the rate at which the kiln would heat up if it was full on. The cooling rate cannot exceed the rate at which the kiln would cool if it was turned off. At full speed the elements are on all the time. During set ramps and holds they turn on and off repeatedly to maintain the heating rate, hold temperature, or cooling rate.

KILN FURNITURE: A GENERAL INTRODUCTION IMPORTANT
Paragon Kiln Shelf Kit. Paragon Rectangular Kiln Shelves. Paragon Round Kiln Shelves. Paragon Mixed Kiln Shelves.

Kiln Furniture: Rectangular, Round, Hexagonal, and Octagonal Shelves, And Posts.

Most kilns have a recommended furniture kit. Delivery companies have a low rate for parcels less than 30kg so, for smaller kilns weighing less than 30Kg, the kit is generally one shelf and four posts: included in the price because it fits in the box and doesn't add much to the overall weight.

You get a professional, durable, cordierite shelf with four 12mm high posts. You don't get a soft, ceramic-fibre shelf, often described as free, that will gradually break up and need replacing.

Shelf kits for rectangular or square kilns usually include four 25mm x 25mm x 12mm shelf posts, When flat, they're 12mm high: on their sides, they're 25mm. Other sizes, up to 150mm high, are available, so you can choose the shelf spacing that suits your kiln and your work. Shelves for cylindrical kilns usually have three posts.

The recommended kit is usually the simplest that works: not an expensive collection that I've put together for you. However, extra shelf kits allow you to stack your work, optimising your use of the firing chamber volume, the unit-cost of firing, and your time. And extra half-shelves or smaller shelves allow you to fire a mix of shorter and taller pieces.


For larger kilns weighing more than 30Kg, shelf kits are not included in the price because you'll probably want to choose your own mix of shelves, half-shelves, smaller shelves, and assorted-height posts.


One shelf should stay on the floor of the firing chamber all the time in case you accidentally spill or melt anything: solidified glass or metal is impossible to pick off without damaging the ceramic-fibre or firebrick.

Shelves are not meant to be an exact fit in the kiln. You need finger space all round and they mustn't scrape the kiln walls every time they're put in or taken out. Be careful lifting heavy shelves out of a top-opening kiln: if you drop them they will damage the firebricks.

Although they look tough, most ceramics break if they're dropped on a hard floor, so it's a good idea to have spare shelves, especially if your business depends on your kiln or you're running courses.


During firing sequences with heating, holding, and cooling segments, the elements turn on and off repeatedly. In a small kiln, with little residual heat, the inevitable temperature changes can make glass crack as it expands and contracts. A thick heavy shelf stores heat and, because it's resting on posts, the air circulates, helping to even out the normal temperature fluctuations.


If you're buying your first kiln, you're probably interested in one material, such as silver clay, or one process, such as enamelling. However, after a few successes, and failures, most people want to try different materials, make larger pieces, experiment with combinations, fire more at a time, and soon become interested in something else: or everything else. Some start a business or run classes.

You might want a full shelf, two half-shelves, several mixed shelves, a set of shelf posts, a bead-mandrel holder, glass separator, hot gloves, kiln wash, a knife-making rack, pyrometric cones, a tile holder, or other accessories.

Shelves are heavy, so kits ordered separately need a box and protective packing and attract an extra delivery charge. Outside the UK mainland, this might be expensive. So, if you think you'll need them, order them with your kiln, along with any other accessories, materials, parts, or tools.


For dichroics, enamelling, and glass fusing, put kiln paper on the shelf to stop the glass sticking: it's simpler and cleaner to use than glass separator. Bullseye Thinfire shelf paper, probably the most popular, ensures easy separation between your glass and the kiln shelf. One side feels slightly smoother than the other: that's the glass side.

Generally, glasswork needs radiant heat and will fuse, sag, or slump better on one shelf than between closely stacked shelves, although experienced glass artists often use several shelves successfully.

Delicate pieces can be fired on a puffed-up ceramic-fibre cloth: on a shelf. Round pieces, that could roll to one side, can be fired on a hollowed-out ceramic-fibre block. However, if the kin has elements in the bottom as with the Mini-Kiln and Prometheus Pro-7, a cloth or block will act as insulator and the kiln might overheat.

Particulates represent a health risk if they're breathed in, so wear a HEPA mask when cleaning out your kiln, mixing kiln wash, and working with ceramic-fibre blocks, ceramic cloths, and papers. And, ideally, use protective glasses.

If you want to touch anything hot, or move your kiln before it's cooled off, it's important to wear heat-resistant gloves. And, if you want to look into a red-hot kiln, even briefly, wear glare-resistant glasses to protect your eyes from IR and UV.


If your day-to-day work depends on your kiln and down-time will be disruptive or expensive, it's a good idea to have spares: extra shelves, a selection of posts, elements, a relay, and a thermocouple.

You can learn about ceramic blocks and cloths, charcoal, dust masks, glare-resistant glasses, glass separator, heat-resistant gloves, kiln vents, kiln wash, programmers, protective glasses, USB interfaces, shelf paper, tools, and other accessories, using the accessories link below the menu bar near the top of the front page. And they're all in the on-line shop.


Shelves are checked before despatch and are wrapped protectively. But they're not guaranteed and we cannot be responsible for any later damage.

OPTIONS AND UPGRADES: A GENERAL INTRODUCTION
Paragon Xpress E9A Jewellery Kiln With A Sentry Xpress Programmer: Purple. Paragon Bead Door. Paragon Door Window. Paragon Solid State Relay.

Options And Upgrades.

It's important to learn about options and upgrades now as some have to be factory-fitted. The photo shows a Paragon Xpress E9A customised for a PMC silver clay studio: purple, with the maximum temperature set to 925°C so that students couldn't accidentally melt their silver.


An option is cosmetic or practical, such as a black respray, a right-hand door hinge, a peephole-vent, a bead-annealing door, a door or lid viewing window, or an EU plug.

An upgrade extends the standard specifications, such as a higher maximum temperature, a 3-key to a 12-key programmer, an electric kiln vent, a gas injection control system, an auxilliary power output, or a USB computer interface.

Not every option or upgrade applies to every kiln, so mail or call if you need help. However, if they're appropriate, they're listed in the on-line shop, so just add up the ones you want: but order them with your kiln as they're often difficult, expensive, or impossible, to implement afterwards. It might help if you make a few notes of your own as you read?


Kilns use regular single-phase 230V-240V mains so have 230V EU elements, not 120V US elements. The smaller kilns have UK 13A three-pin plugs: so they're ready to go. If you're not in the UK, use a plug adapter or cut off the UK plug and fit your own: it won't invalidate the guarantee. Alternatively, a special-order kiln can have a factory-fitted EU plug.

Most kilns can be re-engineered for 110V, 200V, 208V, or 220V, single phase or three phase, or 440V three phase. If you're interested, mail or call.


Although standard EU and US kilns have the same maximum temperature, set by the design and the programmer, some 1095°C firebrick kilns can be re-engineered to run at 1230°C, 1260°C, or 1290°C, making them versatile mixed-media kilns. However, to use 1290°C full-on hour after hour, choose an industrial or professional model.

Also, to maintain 1290°C, some upgraded kilns might need thicker firebricks, so they'll be slightly smaller inside: about 12mm on each side. Mail or call if you're interested, or need help deciding.

The UK factory-set maximum temperature is based on a reliable average voltage of 240V. If there's a regional, national, or temporary voltage drop, high-temperature kilns might take longer to reach their specified maximum or not reach it.


Some kilns are normally blue, but can be factory-painted berry, black, jade, navy, pink, purple, or turquoise. However, as they're made to order, they can't be returned if the colour isn't exactly the same as in the photo.

Changing the door hinge might be better if your kiln is in the corner of your studio or there's an obstacle that will make access difficult. Give this some thought.

Most of the medium-size top-opening kilns have a standard lift-up lid. Firebrick lids seem heavy to some people so, if you feel that a ceramic fibre lid, a hydraulic-assisted lid, or spring-assisted lid would be easier, mail or call.


If the kiln comes with a Sentry Xpress 3-Key ramp-hold programmer, you can upgrade to a Sentry Xpress 3-Key cone-fire ramp-hold programmer, usually preferred for ceramics. Cone-fire is implemented in the programmer's software and is very easy to use: just set a cone number and start the firing sequence.

Depending on the kiln, you can upgrade a Sentry Xpress 3-key programmer to a Sentry 12-Key ten segment ramp-hold, or cone-fire ramp-hold, programmer, with advanced firing features and connection options. The 3-key has a 12-month guarantee and the 12-key has a 30-month guarantee.

A Sentry 12-key programmer can be connected to your computer through a factory-fitted USB interface. The Control Master software allows you to control and monitor the firing, and analyse, arrange, print out, and save the data. If you want this feature, make sure you order the USB interface in the on-line shop.


Depending on the kiln, the 12-key programmer has a power-ratio feature: you can adjust the heat balance between the top and sides in 10% steps and control the heat distribution over larger pieces.

Kilns which only heat from the top, as opposed to the top and sides, don't have the power-ratio feature. However, the initial cost-saving has to be offset against fewer firing options.


With larger kilns, serious glass artists are always concerned about firebrick dust from the lid falling onto their work, so you could upgrade the standard firebrick lid to a factory-fitted ceramic-fibre lid with the elements threaded through pinless grooves in the fibre: or, as a luxury upgrade, with the elements completely embedded in the fibre.


Most kilns come with an electro-mechanical long-life nickel-chromium K-type thermocouple. However, if extra long-life and reliability are vital, you can upgrade to a mercury relay which has a lifetime of several million on-off cycles. The relay can switch 30A, so if you have a kiln that needs 50A, you'll need two relays.

If extra long-life and reliability are vital, especially at temperatures above 1100°C, you can upgrade to a long-life S-type platinum-rhodium thermocouple.


Some front-opening kilns are just too large and too heavy for a regular worktop, so Paragon makes a strong steel table, 768mm x 768mm x 718mm high, with two shelves for your accessories. The luxury version, with castors, is 63mm taller. If you decide to buy on old wood table, the rigidity of the legs is vital otherwise it will collapse like a parallelogram.


Some bronze and copper clays, and some metals, need to be fired in activated charcoal granules in a stainless steel container. The SC2 and SC3, the Caldera-A, and the Xpress E9A and E10A can hold a one-litre container: most other kilns can hold a three-litre but check the internal size before you buy the container. It's important that the container doesn't touch the thermocouple.

Particulates represent a health risk if they're breathed in, so wear a HEPA mask when cleaning out your kiln, mixing kiln wash, and working with charcoals, ceramic-fibre blocks, cloths, and papers. And, ideally, use protective glasses.

If you want to touch anything hot or move your kiln before it's cooled off, it's important to wear heat-resistant gloves. And, if you want to look into a red-hot kiln, wear glare-resistant glasses which protect your eyes from IR and UV.


Paragon kilns, made in the US, have been re-engineered and comprehensively tested for the UK, the EU, and most other countries. They're CE Marked and comply with EU safety standards. They're guaranteed for a year, and Paragon has an international, informed, and supportive user-base, and spares and repair centres.

The UK-EU digital programmer shows degrees Celsius, not degrees Fahrenheit as in the US. If you need to convert, this is how to do it. However, if you want to work in Fahrenheit, you can make a simple change to the programmer.


For help, or in the unlikely event of a fault, you can mail or call an engineer in the UK. However, home checks, adjustments, and repairs are quick and easy, needing little more than a PosiDriv screwdriver, and you can watch on-line videos. Alternatively, we can repair the kiln in our workshop at Cherry Heaven.

As with a lot of heavy consumer products made in the US but sold elsewhere, Paragon's guarantee covers replacement parts, not a return to the distributor or factory, and not any labour costs. However, as an example, replacing a programmer takes just a few minutes.

AN ELECTRIC KILN VENT
Orton-Paragon VentMaster: Unassembled. Vent Outlet. Auxilliary Power Socket.

The Orton-Paragon Vent Master Kiln Vent.

Refreshing the air in a kiln minimises surface blemishes when firing clays, ensures brighter colours when firing glasses, and prevents colour contamination when firing different glazes.

A factory-fitted Paragon-Orton Vent Master removes airborn pollutants straight away and redirects them to the outside through a flexi-pipe. The kilns can be factory-readied, so the vent just needs on-site assembly.

The vent motor isn't so powerful that the heat-up time and maximum temperature are reduced, but the cooling time is, depending on the size of the kiln.


The UK-EU vent motor is rated at 230V-240V 132W, so it can use a regular mains socket. The suction cup, in the second photo, and pipe are attached to the kiln but the motor can be remote: it doesn't get hot and the fan is easy to clean.

There's always a small gap, for expansion, around any kiln door or lid, so enough new air can be drawn in to replace the old air being drawn out. However, peepholes act as straight-through cold-air inlets: so you might not want them or block them with some ceramic cloth?

The vent can be turned on and off manually. Alternatively, if the kiln has a Sentry or a Sentinel programmer, the vent can be plugged into the kiln's auxilliary power outlet and controlled by the programmer. The power outlet, in the third photo, has to be fitted during manufacture, so decide before you order.


As with Paragon kilns, Orton Vent Masters can be re-engineered for any electrical system. They conform to the demanding 1992 Uniform Mechanical Code and the UL standard, and are CE Marked for the EU. They have a two year limited warranty.

A GAS INLET FLOW METER
Paragon Gas Inlet Flow Meter.

The Paragon Gas Inlet Flow Meter.

During heat treating, oxygen forms a scale on the surface of knife blades, metals, and tools. To minimise this, the parts can either be wrapped in heat-treating foil or an inert gas can be injected into the furnace to displace the oxygen.

Most professional knife makers use gas injection for precise control and to save time. If you have a Sentry or a Sentinel Touch Screen programmer, a solenoid kit can automatically turn the gas on or off for each segment of the firing: just programme the controller to turn on the gas at the temperature where scale begins to form on the steel.


In addition to the flow meter, you'll also need a regulator to reduce the pressure from the gas tank. This is usually bought with the gas tank: it's not part of this Paragon option. The gas pressure to the flow meter should be less than 20 pounds per square inch.

Furnaces aren't air tight and gas will leak out through the firebricks and metal seams, so you need a steady flow of gas. Gas at room temperature will expand to over twenty times its volume when injected into a firing chamber at 550°C, so a low setting on the flow meter is adequate to prevent most scaling.


Depending on how you work, gas injection might reduce the life of the heating elements slightly. However, they're easy and inexpensive to replace. If your business depends on continual kiln time, buying a spare set of elements would be sensible.

Argon gas is popular for heat treating because it's inexpensive. But, it's heavier than air and breathing it in won't keep you alive. so your workshop must be well ventilated.

A USB INTERFACE WITH WINDOWS SOFTWARE
Paragon USB Interface.

The Paragon USB Interface With Windows Software.

A factory-fitted USB interface provides a USB socket on the kiln that connects a Sentry or Sentinel programmer to a Windows computer. You can monitor the firing sequences, save them, and print out the results, making it easier to keep a record of firings: successful and unsuccessful. If you prefer, you can have an RS232 interface.


The Universal Serial Bus, USB, is a simple plug-and-play digital connection between a computer and most of it's peripherals, designed to replace all the old plugs, sockets, cables, and expansion interfaces. Up to 127 fast-access devices can be set up automatically and hot-swapped without turning the computer off.

Universal means it's an internationally agreed standard. A bus is the computer's two-way connection which carries data between the processor, the drive, the memory, and the peripherals. Serial means that data is sent one bit after another, as a data stream.
As an analogy, a road bus carries passengers between work, home, and the shops. And a tee-vee serial shows the episodes one after another, in the right sequence.

FIRING CHARACTERISTICS

How Electric Kilns Work.

Generally, as soon as a programmable kiln starts its firing sequence, it begins to heat up at a rate set by the programmer. It can't heat up quicker than it would do with the elements full on all the time.

The thermocouple tells the programmer the current internal temperature and, depending on the sequence you've chosen, the programmer turns the elements on or off to control the sequence segments: the heating rate, the target temperature, the hold time, and the cooling rate. It can't cool down quicker than it would do with the kiln turned off. When the sequence is complete, the kiln beeps, and the sequence stops.


For safety, the programmer doesn't switch the full mains voltage. Instead it drives a relay, an electro-mechanical switch. The programmer uses a low voltage to activate the switch which turns the high-voltage high-current elements on or off.


When the target temperature is reached, the programmer switches the elements off. However, residual heat in the firing chamber allows the internal temperature to overshoot the target temperature briefly before starting to fall back.

This overshoot is more evident at low temperatures than at high temperatures, and in small kilns rather than large kilns. For example: 300°C will probably overshoot to 350°C whereas 800°C will probably only overshoot to 805°C before starting to fall back.

However, our Sentry Xpress programmers have a software modification that slows down the heating just before the target temperature, reducing any overshoot and improving the accuracy.

During the hold-time, with the elements still off, the temperature starts to fall. When the programmer switches the elements back on, the firing chamber will initially absorb some of the new heat before the temperature recovers. The continual switching of the elements on and off causes the internal temperature to oscillate either side of the target temperature.

This is similar to central heating. If you set it for 21°C, it probably oscillates, quite slowly, around 20°C to 22°C: and you won't notice. The accuracy will depend on where the thermostat is sited, how quickly it responds, how accurate it is, how long it takes for the radiators to heat up, and if you have doors and windows open. The temperature will probably be different in each room.

So, regardless of the thermocouple temperature, the actual temperature of your work will be slightly different, depending on its position on the kiln shelf, the vertical spacing of any stacked shelves, and its nearness to the elements, a lid, a door, a bead door, or a window. Learn to take this into account if you're working with temperature-critical materials or processes.


Remember that glass needs radiant heat and will fuse, sag, or slump better on one shelf at the bottom than between closely stacked shelves.


Kiln doors and lids are not meant to be a perfect fit otherwise, at high temperatures, there'd be no room for expansion and movement, and the door could stick and the ceramic-fibre or firebricks could crack.

All kilns smell a bit, and even produce whisps of smoke, during the first firings, just like a toaster or a fan heater. If you're worried about fumes, open a window.

Eventually, with normal use, kilns discolour slightly, inside and outside, and some firebricks might develop hairline cracks. Your kiln is a versatile, robust, red-hot tool: not an ornament.

KEEPING A KILN LOG

Keeping A Kiln Log.

Using your kiln successfully needs critical research and frequent tests, especially as things that work for your friends and teachers might not work in the same way for you. It's also very important to learn how to creatively use unexpected effects. So, keep a firing log:


Buy a durable notebook. Use a new page for every firing, and draw diagrams of the shelves, their vertical spacing, and the position of your work on the shelves. Along with your work, put a few scraps at different places on the shelves to learn how things change. Describe the material, the shape of your work, the firing cycle, and the end result. Add a few photos and sketches, and mark the page corners with coloured dots or symbols as a quick reminder of your success rating.

A kiln log is vital if you're experimenting with temperature-sensitive materials or working with metals, coloured dichroic glasses, enamels, glazes, or china paints, and a skilled artist will use the kiln log to advantage to re-create effects. It'll be particularly useful if you have to repeat a commission, or you have a long holiday before returning to your studio.


Some Paragon kilns have a Sentry 12-key or a Sentinel Touch Screen programmer which can be connected to your computer through a factory-fitted USB interface. The Control Master software allows you to control and monitor the firing, and analyse, arrange, save, and print out the data. If you want this feature, make sure you order the USB interface in the on-line shop.

A BRIEF INTRODUCTION TO MAKING KNIVES

Steels And Knife Making.

Steels are alloys of iron and carbon, generally described as mild steel, medium-carbon steel, or high-carbon steel, according to the percentage of carbon. Adding other elements such as chromium, manganese, nickel, tungsten, and vanadium change the characteristics of the metal.

There are over 3500 types of steel, most of which have been developed during the last 25 years. If the Eiffel Tower were to be built today, it would only need one-third of the steel that was originally used.

Making knife blades involves many different types of high-carbon steel and a series of forming, heating, cooling, and finishing processes. Knife-making kilns come with a heat treating manual, although professional knife-makers usually adapt the processes and develop their own techniques.


During heat treating, oxygen combines with the steel to form a scale on the surface of the blades. To minimise this, they're either wrapped in heat-treating foil or an inert gas can be injected into the furnace to displace the oxygen.

Some knife-makers use 321 stainless steel foil to wrap the blades, mimicking a vacuum furnace. The foil needs to be removed before quenching the steel in oil.

Others use a water-based coating. The steel part can be painted, sprayed, or dipped then allowed to dry before beginning the heat treatment. On cooling, it will crumble off and the steel parts can be rinsed clean under water. It's important to ensure that parts are clean of oil and greases before applying the coating.

Most professional knife makers use a kiln with gas injection for precise control and to save time. The Sentry 12-key and the Sentinel SmartTouch programmers can have an additional solenoid kit which can automatically turn the gas on or off for each segment of the firing: just programme the controller to turn on the gas at the temperature where scale begins to form on the steel.

Argon gas is popular for heat treating because it's inexpensive. But, it's heavier than air and breathing it in won't keep you alive: so your workshop must be well ventilated.

HARDENING STEEL

How To Harden Steel.

Steel is already hard, but can be made much harder by heating it to a hardening temperature and then soaking it at that temperature. The temperature and time depend on the steel and the result you want. Hardness is measured using Rockwell testing.

QUENCHING

How To Quench Steel.

After hardening, steel is quenched by cooling it in air, water, or oil, otherwise the steel would lose most of its hardness. The way in which quenching is done is vital.

TEMPERING

How To Temper Steel.

After quenching, most steel is tempered, another heating and cooling process, to relieve stresses, otherwise it can be too brittle for repeated use.
