Jen-Ken AFG Double Wall Crucible Glass Kiln

Built for professional glass artists, the Jen-Ken Double Wall Crucible Kiln delivers precision, performance, and durability for molten glasswork. Its double-wall insulated design enhances heat retention, ensures even temperature distribution, and keeps the exterior cooler—making it both energy-efficient and safer to operate. Designed for melting cullet (not batch glass), it reaches up to 2300°F to melt, cools to 1800°F for squeezing, and maintains a steady 2050–2100°F for consistent gathers.

Solid-state relays come standard, offering quiet, reliable operation and precise temperature control. Artists can add the optional furniture kit (kiln shelf and four bricks) for setup flexibility and stability during use.

Comes standard with the Orton AF3P 3-Button Controller for dependable, easy programming. For enhanced precision and control, upgrade to one of three advanced controllers:
– Orton AutoFire 4000 12-Key Controller – expanded programming capacity and precision tuning
– Orton AutoFire Slide Touchscreen Controller – modern interface with intuitive control
– TAP II Touchscreen Smart Controller – Wi-Fi connectivity, cloud storage, and real-time firing data

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.)
