Jen-Ken AF3P 24-E 15" Glass Kiln

For artists seeking greater depth and flexibility, the 24-E 15" expands your creative potential with a 24” x 15” interior—ideal for deep slumps, drop molds, tall slumping projects, and large fused panels up to 20" round or 15" square. Its dual top-and-side firing system provides even, consistent heat throughout the chamber for flawless glass fusing and slumping results.

Standard lid lifters reduce lid weight for effortless opening and closing, while optional solid-state relays offer silent, precise temperature control for frequent studio use.

Comes standard with the Orton AF3P 3-Button Controller for reliable, straightforward operation. Artists can upgrade to one of three advanced controllers for increased precision and customization:
– Orton AutoFire 4000 12-Key Controller – more programs and finer control
– Orton AutoFire Slide Touchscreen Controller – sleek, responsive touch interface
– TAP II Touchscreen Smart Controller – Wi-Fi connectivity and real-time data tracking

An optional furniture kit (21" shelf and ½" posts) adds flexibility for layering or specialized setups.

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.)
