Jen-Ken AF Ceram-a-Glass Oval 3" Kiln – Maximum Capacity Dual-Media Firing Power

The Jen-Ken AF Ceram-a-Glass Oval 3" is a large-format dual-media kiln built for studios that need serious capacity and the flexibility to fire both glass and ceramics. With a massive 39" × 24" × 18" chamber and 3" brick insulation for superior efficiency and heat retention, it’s ideal for production-scale glass artists, ceramicists, and mixed-media makers. Its oval interior fits two 21" × 18" D-shelves, forming a generous 21" × 36" firing surface—perfect for large slumps, wide platters, fused panels, and bigger bisque or glaze loads.

A dedicated glass/ceramic switch tailors heating mode to your project: top-focused heat for smooth, even glass results, and controlled side-element firing for clay up to ~Cone 6 (≈2150°F). Lid lifters make opening and closing effortless despite its generous size.

This kiln includes a standard 45-amp plug-in configuration for low-fire and mid-range use, with an optional 55-amp direct-wire upgrade for enhanced power delivery and extended element life during frequent firing cycles.

Standard with the Orton AutoFire 4000 12-key controller, this kiln delivers consistent firing profiles with room to grow. For advanced workflows, upgrade to a touchscreen controller for even more precision and convenience.
