    Uses: China Painting Decals Dolls Fast Firings Glass Fusing Low-Fire Ceramics Porcelain and Stoneware

    The Optional Glass Window

    You can order your Caldera-S with an optional glass window in the top. The 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.)

    Optional Extension Collars

    The Caldera line of kilns from Paragon can be used with optional extension collars to add additional functionality for bead annealing, enameling, or just a little extra internal volume for slightly taller projects. Click here to check them out!

  • Caldera S Kiln

    Fire silver clay, china, ceramics, and glass in Paragon’s manual-fire Caldera-S kiln. Test for glass compatibility; test ceramic glazes. Fire rapidly to 2350°F/1287°C. With a separate top and bottom, the Caldera-S is stackable and completely portable. The Caldera-S comes with an infinite control switch, pilot light, and a large, easy-to-read 4 1/2” wide pyrometer.

    Steel Stand, Stackable Design

    The original Caldera and Caldera-S kilns were placed on top of four firebrick blocks. The new kilns now ship with a sturdy 2 3/4" high x 14" x 12 3/4" steel stand, complete with mar-proof rubber feet. With a separate top and bottom, the Caldera-S is stackable and completely portable. The kiln is easy to carry to seminars. Take it with you on vacation.

    The Caldera-S in the Classroom

    A Caldera-S is a nice addition to school programs. A switch-operated test kiln is relatively inexpensive. With the Caldera-S, students can fire gifts in time for a birthday or holiday instead of waiting until the school’s large kiln is full. A test kiln creates enthusiasm for a clay program. Students can test glazes while they feel the momentum instead of waiting to fire them in the large kiln.

    New teachers inherit bags of unlabeled clay in their classrooms. Many loads of clay have been ruined because they were fired to the wrong temperature. With a Caldera-S, you can easily test unlabeled clay.

    Designed for production

    Paragon’s warranty is not affected by frequency of use. Fire your new kiln every day if you want, even in commercial settings. That will have no effect on the warranty period.
