Jen-Ken AF3C 2422 Ceramic/Pottery Kiln

The Jen-Ken AF3C 2422 is the ultimate home-studio kiln—offering the perfect balance of size, power, and performance. Its 22” depth makes loading and unloading simple and ergonomic (a favorite feature among the “vertically challenged”), while its 24” diameter provides ample room for a full 21” shelf or two half shelves, accommodating even larger pottery pieces with ease.

Built for both low-fire and high-fire ceramics, this kiln handles everything from bisque and glaze firings up to Cone 8 (2300°F). With a 42-amp draw and efficient heat distribution, it delivers reliable performance firing after firing, making it ideal for both passionate hobbyists and small production studios.

Powerful, Energy-Efficient Design

The AF3C 2422 is constructed from premium-grade materials for durability and longevity. Its efficient insulation and heat retention make it a dependable and economical choice for studios firing multiple times per week.

An optional Orton Downdraft Venting System adds precise zone control and improved air circulation for even firings throughout the chamber, while integrated Lid Lifters make operation effortless—you can open the lid with just two fingers.

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.)
