Jen-Ken AF Mega Coil 2829-3" Ceramic/Pottery Kiln

Built for serious ceramic artists and busy production studios, the Jen-Ken AF Mega Coil 2829-3" delivers powerful performance, long element life, and incredibly easy maintenance. The oversized Mega Coils—one per full brick—provide exceptional heating efficiency and extended lifespan, while the 3" brick insulation and solid-state relays ensure stable, consistent firings every time.

With a deep 29" chamber and rugged direct-wire 240V design, this kiln excels in studios firing low-fire and mid-range ceramics frequently. It fires up to Cone 8 (~2300°F), making it suitable for functional ware, glazes, and stoneware work while minimizing wear on elements during repeated production cycles.

If service is ever needed, Mega Coils can be replaced in about 10 minutes without a technician—minimizing downtime and keeping your workflow moving. Lid lifters are standard for easy loading, and a sectional build option is available for narrow-door installations.

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.)
