Jen-Ken AF3C 2431 Ceramic/Pottery Kiln

The Jen-Ken AF3C 2431 is a dependable, large-capacity kiln built for schools, paint-your-own pottery studios, and production environments that need reliable cone 04–06 firings multiple times per week.

Included lid lifters make loading and unloading smooth and strain-free.

Powered by a 45A NEMA 6-50 plug, this kiln is ideal for facilities equipped with standard studio electrical service. Constructed with premium firebrick and rigidized fiber, it maintains consistent heatwork and reliability for steady studio use.

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

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.)
