PARAGON CT122829 Janus: Massive Capacity, Maximum Flexibility—for the Serious Clay and Glass Studio
The Paragon CT-122829 Janus Kiln is a versatile, front-loading ceramic and glass kiln designed for artists and studios who work across multiple firing disciplines. With a spacious 28" wide x 29" deep chamber, the Janus model combines the best of both worlds—configured with both ceramic and glass heating elements to allow flawless clay firings up to Cone 10 (2350°F) and precise glass fusing, slumping, or annealing at lower temperatures. This dual-function kiln gives you full creative flexibility, whether you're working in stoneware, porcelain, or fused glass. The Sentry Digital Controller supports detailed firing schedules, ramp-and-hold programming, and consistent, repeatable results. Built with durable firebrick insulation and a sturdy steel frame, the CT-122829 Janus is ideal for high-capacity studios, educational spaces, and professional artists who want one kiln that can do it all.
Built on the Ceramic Top legacy—now equipped for dual-firing mastery.
The PARAGON CT Series, long trusted by production studios and art programs alike, is known for its power, durability, and user-friendly engineering. The PARAGON CT122829 Janus builds on that legacy with a bold combination of size and versatility: a powerful, high-volume kiln that fires both ceramics and glass through an intuitive mode-switching system.
Whether you’re tackling large-scale sculpture or multi-layered glasswork, the CT122829 Janus adapts to your creative needs without compromise.
Why choose the PARAGON CT122829 Janus?
As the deepest and most spacious kiln in the CT line, the CT122829 Janus offers a commanding 10.57 cubic feet of firing space, with a 28” interior diameter and 29” interior height. This massive capacity supports everything from tall, hand-built forms to fully stacked production runs of functional ware or glass panels.
Now upgraded to 48 amps, this kiln delivers faster heat recovery and greater power, supporting consistent, repeatable performance—even in high-volume firing cycles.
And with Janus dual-mode firing, you get all this performance in one unit that does it all.
Janus Dual-Mode Firing: Glass or Pottery with the Flip of a Switch
The defining feature of this model is its dual-element system—with heating coils in both the top and sidewalls. You can switch between firing modes depending on your material:
-
Glass Mode: engages the top and middle sidewall elements—ideal for fusing, slumping, or sagging large glass pieces on a single shelf.
-
Pottery Mode: uses only the sidewall elements for even, surround heat distribution—perfect for cone 10 ceramics, bisque, glaze firings, or stacked ware.
This flexibility makes the CT122829 Janus a powerhouse for schools, production shops, and mixed-media studios that need one kiln to do it all.
