Jen-Ken Ceram-a-Glass 2822 3" Kiln

This kiln is built for artists who need serious firing capacity and the flexibility to work in both glass and ceramics. With a full 26" shelf capacity, 22" depth, and 3" brick insulation for superior heat retention and energy efficiency, this is a powerhouse dual-media kiln for ambitious home studios and professional makers.

A dedicated glass/ceramic switch allows you to fire efficiently in either mode: top-element heating for smooth, even glass results, and controlled side-element firing for ceramics up to cone 6 (≈2150°F). Lid lifters come standard for smooth, low-effort operation on this large-format kiln.

Standard with the Orton AutoFire 4000 12-key controller, the 2822-3" offers reliable, repeatable control. Upgrade to a touchscreen controller for enhanced programming, mid-firing edits, and intuitive temperature control.

Choose the voltage that matches the electrical service where the kiln will be installed. Some kilns are available in only one voltage, while others can be ordered in multiple voltages. If both 120V and 240V are available, 240V is generally the preferred choice because it places less demand on your electrical system, while 120V offers the convenience of operating on a dedicated standard household circuit. If both 208V and 240V are available, select the voltage that matches your building's electrical service—240V is most common in homes, while 208V is common in many commercial, educational, and institutional buildings. If you're unsure which voltage you have, confirm it with your electrician before ordering.

Your kiln must be built to match the electrical service where it will be installed. Choose single-phase if that's what your building has (almost all homes do). Choose three-phase only if your building has three-phase power available. If both are available, three-phase is generally the preferred option. If you're unsure, verify the available electrical service with your electrician before placing your order.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
