The Paragon Caldera-A Kiln For Beads, Ceramics, Dichroics, Enamels, Glass, Heat Treating, Metal Clays, Porcelain, And Vitrigraph.

The Paragon Caldera-A kiln is generally used for ceramics, dichroics, enamels, glass fusing, heat treating, metal clays, porcelain, testing glazes, and vitrigraph, although it has other applications. It's a 1290°C kiln with a digital programmer, in Paragon blue, or customised berry, black, jade, navy, pink, purple, or turquoise.

There are eight versions: the Caldera-A, AB, AC, AE, AW, ABW, ACW, and AEW. The B versions have a clip-on collar with a bead-annealing door, C have a clip-on plain collar, and E have a clip-on collar with an enamelling door. The W versions have a heat-resistant glass viewing-window in the lid.

For prices, use the shop link below the menu bar near the top-right of any page. They're for UK-EU voltage, CE-marked, TUV tested, and CL and CSA approved kilns.

Heavy guage long-life nickel-chromium K-type thermocouples replace the older US bead-style and sheathed-style. They respond more quickly to temperature changes and minimise the risk of corrosion and subsequent failure of the bi-metallic tip: often caused by epoxy break-down and the gases produced whilst heating some materials.

The kiln furniture comprises a solid thick durable cordierite shelf for even heat distribution, and four 12mm shelf supports: not the thin US-style fibre shelf.

Prices include the pro shelf kit, comprehensive instructions, UK delivery, UK VAT, and continuing free support from a top-tier international distributor. So you can start work straight away.

The Paragon Caldera-A Kiln For Annealing, Beads, Ceramics, Enamelling, Glass, Heat Treating, Silver Clays, Porcelain, And Vitrigraph.

Paragon Caldera-A Ceramics And Glass Kiln Sentry Xpress Digital Programmer

The Paragon Caldera-A is a 1290°C, square, top-opening, plug-in, table-top, firebrick kiln, with a cone-fire ramp-hold Sentry Xpress 3-key digital programmer. Choose Paragon blue, or customised berry, black, jade, navy, pink, purple, or turquoise.

The UK kiln is rated at 230V-240V 1680W, so it can use a regular mains socket. To comply with EU safety regulations, it's fitted with an additional lid-activated switch that cuts off the power if the kiln is opened: an important safety feature included in the price. However, never get careless: kilns are very hot and connected to the mains.

The kiln has two clip-together parts: a firebrick base, and a firebrick firing chamber with a hinged firebrick lid. The outer steel case measures 330mm x 495mm x 349mm, including the programmer housing, other hardware, and the 70mm-high base, and has four lifting handles on opposing sides. The electrical components, located on the front, stay cool, even at extended hold times. The shipping weight is about 21Kg.

The firebrick firing chamber measures 203mm x 203mm x 171mm high, and heats from all four sides, with the fast-firing elements lying in pinless dropped-recessed grooves in the 64mm thick bricks. The kiln has an electro-mechanical relay and a nickel-chromium K-type thermocouple.

The bottom of the firebrick lid, and the meeting surface of the top row of firebricks, are hardened and sealed with refractory cement for long life and minimal brick dust.

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

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

List a berry, black, jade, navy, pink, purple, or turquoise respray: normally blue
List a long-life mercury relay upgrade: factory fitted
List a long-life S-type platinum-rhodium thermocouple upgrade: factory fitted
List stacking 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 Caldera-A is a high-temperature kiln, made for years of continual firing. Because it's small and heats up quickly, it's popular for ceramics and glass work at home, or in a course venue, studio, or workshop: everything from fusing glass to firing porcelain.

The Caldera-A is stackable, with a separate bottom, an optional collar, the main body, and a hinged lid. If you don't need the versatility of the collars now, you might do later on: so read about these before choosing?

Vitrigraph uses a Caldera-A to make glass stringers. The bottom of the kiln is unclipped and set aside. The kiln body is put on a thick ceramic square with a central hole. The whole thing is lifted well away from the floor to allow moulten glass to fall through a small hole in a crucible and form long stringers. Ceramic squares are in the on-line shop.


The Paragon Caldera-A Kiln Furniture.

There's a recommended kit, included in the price: one 178mm x 178mm x 15mm cordierite shelf, four 12mm shelf posts, and 450gm of kiln wash.

There's an extra recommended kit, not included in the price: one 178mm x 178mm x 15mm shelf and four posts. You can choose 12mm, 25mm, or 50mm posts.

Depending on the material or process, and the sizes of your pieces, stacked shelves will hold more work, free up your time, and reduce the unit firing cost: so you might want more kits. This kiln has room for three.
