PARAGON CALDERA: The Compact Kiln That Does It All

Important shipping note

THIS IS A DROP SHIPPED OR SPECIAL ORDER ITEM. PLEASE CONTACT OR LEAVE A NOTE IN THE COMMENTS BOX REQUESTING ESTIMATED WAIT TIME FOR SHIPPING

Overview

The PARAGON CALDERA is a small kiln with an extraordinary range. Designed for artists, hobbyists, and educators who demand flexibility and performance, this tabletop kiln can fire metal clay, glass, ceramics, enamel, and more—all in one compact unit. Whether you’re fusing dichroic glass, sintering silver clay, or testing stoneware glazes, the CALDERA is your all-purpose creative companion.

Firing up to 2350°F (1287°C), it brings professional capability to your bench or classroom.

Versatile and Addictive for Glass and Metal Clay Artists

Explore an entire spectrum of techniques with the CALDERA:

  • Fuse, slump, and sag glass into pendants, bowls, and earrings

  • Fire fine silver, bronze, and copper clays into finished jewelry

  • Test glazes and fire small ceramic pieces or stoneware experiments

  • Create enamel on copper and fuse china paints or decals

  • Some artists even convert the CALDERA into a vitrigraph kiln by modifying the firebrick base—adding a hole to pull molten glass for flowing stringers and patterns

This kiln is ideal for personal projects, workshops, or schools looking to expand their creative capabilities without investing in multiple units.

Modular Expansion for Evolving Needs

Unlike most compact kilns, the CALDERA is modular. Expand its capabilities with purpose-built collars:

  • Caldera-BC Bead Collar – Adds 4.5" height and a 7.5” x 2” bead door for annealing mandrels

  • Caldera-X Collar – Same height as the BC, without bead door

  • Caldera-E Enameling Collar – Adds 6.75" of vertical space for enameling or taller workpieces

These collars stack onto the base kiln to match your firing goals—making the CALDERA a truly customizable kiln system.

Built to Endure Years of Use

The CALDERA is crafted with the same reliability and build quality found in all Paragon kilns:

  • 2.5” insulating firebrick walls for efficiency and stability

  • Dropped, recessed grooves protect elements for extended life

  • L-shaped lap joints at corners add strength beyond mitered or butted designs

  • Heavy-duty element connectors and steel stand with mar-proof feet

  • Vented switch box and rugged wiring for long-term service in busy studios or classrooms

Even the firebrick base is reversible, allowing you to flip and extend its life in case of wear.

Smart Digital Control with the Sentinel TouchXpress

Every CALDERA comes equipped with the Sentinel TouchXpress digital touchscreen controller, giving you complete control over ramp rates, hold times, and firing schedules. Store custom programs, monitor real-time temperature, and switch between glass and ceramic profiles with just a few taps.

For glass artists, an optional high-temperature window (rated to 2300°F) lets you monitor fusing progress. Note: using the window reduces the kiln’s max temp to approx. 2100°F—still ideal for most glass and enamel applications.

Ideal for:

  • Jewelry makers working with silver clay, bronze, copper, porcelain, or enamels

  • Glass fusers needing a compact unit for small projects or samples

  • Potters and ceramicists testing glaze compatibility or claybody performance

  • Teachers and classrooms needing fast results for student work

  • Artists looking for a small kiln that grows with them—and can even be modified for vitrigraph use

  • Sentinel TouchXpress touchscreen controller
