Check out Kiln Comparison and Tips page for comparisons of our kilns, explanations of features and great tips for using your kiln; if you are making a buying decision and don't know exactly which kiln to buy you should check out our Kiln Pros and Cons page. We also have tips on what accessories or kiln furniture you'll want to purchase based on the mediums you are firing posted on the Firing: Kiln and Torch Supplies. Please review both of these excellent sources for must-have information!

This great kiln fires quickly up to 2350°F (without the bead collar). It comes with a separate top and bottom which makes it easy to carry and stackable. Fully programmable with cone fire and 8 segment ramp-hold program.

This kiln is the most versatile of the Paragon kilns.  Add a collar (no door, bead door, or enameling door) to give additional chamber height, give you access for front loading objects, to allow bead mandrels to exit the kiln, and much more!

The Caldera can ship by UPS. Enjoy lower shipping cost and faster service. Specially designed cartons and foam padding assure that the kiln will arrive safely.

Please note, however, that the window reduces the kiln's maximum temperature to approximately 2100°F (1148°C) and is meant for glass fusing. You can still fire porcelain and stoneware even with the window, but you will need to plug the window with ceramic fiber.  You can purchase this lid separately, giving you the possibility of having a window lid and a regular lid to switch out whenever needed.

ALSO- the Caldera Kiln now comes with the stainless steel base.  It no longer comes with the 4 kiln brick feet.  You do not need to order this if you are ordering the kiln.  We offer it for those customers that have the older Caldera and would like this new base stand.

Fire silver clay, china, ceramics, porcelain, stoneware, decals, enameling, jewelry, and glass in Paragon's digital Caldera kiln. It makes glass compatibility and glaze color tests fast and easy. It fires rapidly to 2350°F/1287°C. With a separate top and bottom, it is stackable and completely portable. The kiln is easy to carry to seminars. Take it with you on vacation. For a digital kiln that can do this much, the Caldera is surprisingly affordable.

To strengthen the firing chamber, the firebrick corners are fitted together with L-shaped notches. This type of joint lasts longer than the butted joint and the "picture frame" mitered joint found on competitive brands. Rugged construction makes this kiln a little workhorse.

Imagine the glass you could make with this kiln: Sag, slump, and fuse. Make small bowls, pendants, earrings, cufflinks, and even bracelets. Enjoy the glittering beauty of dichroics. This kiln will give you a haven of creative enjoyment that you will especially appreciate when life gets hectic.

You will never outgrow a small kiln. If you later buy a larger kiln, continue to use the small one for testing or small projects. Perfect a new design in the small kiln before running production quantities in the large kiln. A small test kiln is invaluable in solving ceramic glaze problems and perfecting difficult glazes such as crystallines.

This kiln is built to last. Elements are coiled from the finest high-temperature wire available. They use heat-dissipating element connectors refined and proven over many years in Paragon kilns.

The Sentry Xpress controller fires in either Ramp-Hold or Cone-Fire mode. Control both heating and cooling with simple 3-key operation. The Caldera includes a safety on/off toggle switch.

The Sentry Xpress 3-key controller is packed with features. It includes two modes: Single Segment and 8-segment Ramp-Hold.

Disclaimer: The specifications above assume that the kiln will be plugged into a dedicated circuit. Local electric codes supersede our recommendations.

The pricing and electrical specifications for the above products reflect their design for use in the United States. The International versions of most models will have variations in electrical specifications and price due to consumer safety requirements or electrical regulations

The furniture kit consists of carefully selected fireclay shelves and posts for this particular model. The furniture allows you to stack multiple layers of ware. Please note this furniture kit is mainly if you are working with ceramics or glass fusing.  Metal Clay users will want to use Hard Fiber Shelves.

Don't forget to order posts and Hard Fiber Shelves for metal clay firings. Corderite, hard clay shelves are only recommended or glass firings and ceramics.  The furniture kit, that is sold by Paragon is the cordierite type with 4 1" posts, and kiln wash.  Unless you are doing glass and ceramics you do not need this furniture kit, but instead you can reference our chart on the Firing and Torch page as to the additional items you might need.
