Paragon Caldera

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.

“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.

The heat of the kiln is magical and offers wonderful surprises. Stained glass, enamels, and ceramic glazes undergo a complete transformation in the kiln. Opening a kiln to view your treasures is a festive moment that you will never outgrow. Artists have said, “Woohooo! Opening a kiln is a celebration!”

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.

The Furniture Kit

The furniture kit consists of carefully selected fireclay shelves and posts for this particular model. When estimating the price of the kiln, include the cost of furniture. The furniture allows you to stack multiple layers of ware. Without it, you could fire only the ware that would fit on the kiln bottom.

Emma Ralph is a prominent, full-time bead maker who lives in Coulsdon, a town in Surrey, England. She has loved making beads since her teens. “Ask any beadmaker--it's an addiction we cannot break!" she said.

Emma fires a Paragon Caldera kiln. “I use my Caldera mainly for batch-annealing small glass beads, but occasionally I fire up some PMC,” she said. “The Paragon Caldera is my first kiln. I have been so impressed with the all-round performance and service. Is there nothing that kiln can't do? It is such a sweetie! I thought the manual and paperwork that came with both the kiln and digital controller were both excellent.

“I particularly appreciate the way that there is so much information for diagnostics and repair / maintenance in the manuals,” she said. “When I showed my engineer husband the various diagrams and technical specs, he made those lovely reassuring noises of ‘ah’ and ‘I see’ that every woman loves to hear. In other words, if anything goes wrong, he can fix it . . . yeah! With so many products these days, if something goes wrong we are expected to trash it and start again. But with the Paragon Caldera, it is so refreshing how the paperwork explains that various parts will wear out from time to time and how they can be replaced.

“The tips in the manual for fusing, annealing and even using PMC were also excellent and very appreciated.
