Paragon Caldera - Retail Price is $795
Fire silver clay, china, ceramics, porcelain, stoneware, decals, enameling, jewelry, and glass in Paragon’s digital Caldera kiln. Glass compatibility and glaze color tests are fast and easy. The Caldera 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.

“I love, love, love the Caldera. I not only fuse glass and work in metal clay, but I teach a lot of classes, so I'm firing the kiln all the time. It is a true workhorse. In three years I have not had one problem with it. I have done drop ring vases, small pot melts, small dishes, and candleholders in it. It is inexpensive to run on 120 volts.” --Lisel Crowley

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 thermocouple, which senses temperature in the kiln, is protected with a high-nickel stainless steel sheath for long life.

You can order your Caldera with an optional glass window in the top. The glass window is rated to 2300°F (1260°C), so it can easily withstand glass fusing temperatures. 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.)

The Caldera switchbox is coated with a durable high temperature, water-base finish. We chose this type of paint because of the low emissions during spraying. This creates a safer working environment for our employees and cuts down on pollution. The Caldera is proudly made in America to exacting standards.

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.
