Jen-Ken AFG Oval 18 Glass/Casting Kiln

The Jen-Ken AFG Oval 18 Glass/Casting Kiln—is built for serious glass and mixed-media artists who need both capacity and control. With its massive 39″ × 24″ × 18″ interior, it easily fits two large panels or a full sink mold, making it ideal for glass casting, fusing, slumping, and even low-fire ceramics. Dual firing modes let you choose between top-and-side heat for fusing and slumping, or side-only for precise casting and ceramic control. Its robust brick construction ensures excellent heat retention, and the included lid lifters make opening and closing smooth and effortless.

Controller Options

This model comes standard with the Orton AutoFire 4000 12-Key Controller for reliable, precise digital operation. Two optional touchscreen upgrades are available for enhanced convenience and smart functionality:

  • Orton AutoFire Slide Touchscreen – modern, intuitive interface with simple, responsive control.

  • TAP II Touchscreen Smart Controller – advanced Wi-Fi-enabled system offering mobile app access, firing data tracking, and real-time control.

Firing Performance

In Glass Fusing mode, powerful top elements deliver even heat, while side coils ensure uniform temperature for flawless slumping and fusing results. Switch to Glass/Casting mode for side-only firing, enabling precise temperature control up to 1,700°F while protecting lid elements—ideal for deep molds, large castings, and low-fire ceramic projects.

Optional Add-Ons

Add an SSR (Solid State Relay) for smooth, silent temperature control, or include a Furniture Kit for flexible shelf setups and multi-layer firings. An optional viewing window is also available to monitor your work during firing.
