An All-Fiber Kiln With Extra Depth. The Bonnie Glo Built for Taller Work.
The AF3P Bonnie Glo Tall takes the same fast-firing all-fiber design as the standard Bonnie Glo and gives it real vertical room. The interior is 15" wide by 9" deep, with 0.5 cubic feet of working space. That extra depth opens up taller fused pieces, light slumping work, and dimensional projects that won't fit in a shallower kiln, while keeping the all-fiber chamber that makes this kiln fire so quickly.
The whole pitch is still about speed. Because the chamber is made from fiber instead of fire brick, most of the heat goes straight into your glass rather than being absorbed by the kiln walls. Quick heat-up, quick cooldown, and the ability to run a few firings in a single day. Jen-Ken's own guidance is straightforward: you can fire glass as fast as the glass can take the heat. The kiln is no longer the limiting factor on the ramp rate.
One thing to know upfront: there's no shelf included, and you don't want a traditional clay shelf in this kiln anyway, since it would slow down the very speed you're paying for. Instead, fire directly on fiber paper, Kaiser Lee board, or lava cloth laid on the chamber floor. These materials are inexpensive, easy to replace, and keep the kiln firing as fast as it was designed to fire.
It runs on a standard 120V outlet with a regular NEMA 5-15 plug. No electrician, no panel upgrade, no studio rewiring. Plug it in and fire. Maxes out at 1700°F, the right range for full fuse, tack fuse, slumping, and glass painting work.
Included with every order
All-fiber kiln chamber and the manual. Plan to add fiber paper, Kaiser Lee board, or lava cloth to fire on, since this kiln is designed to be used without a traditional shelf.
Who Is This Kiln For?
The Bonnie Glo Tall is built for fast workflow on slightly bigger or taller pieces than the standard Bonnie Glo handles. Here's how to tell if it's right for you.
✓ Glass painters and fusers who work on taller pieces
The extra depth over the standard Bonnie Glo opens up taller fused work, light slumping, and dimensional projects that won't fit in a shallow kiln.
✓ Fusers doing small-batch production
Multiple firings per day means you can move through a batch of pieces in a single studio session instead of stretching it across a week. Faster than any brick-built kiln of similar size.
✓ Artists with limited electrical access
120V plug-in operation means apartments, classrooms, basements, garages, or any studio space with a standard outlet can run this kiln without electrical work.
✓ Test kiln for established studios
If you already have a large production kiln, the Bonnie Glo Tall is a smart second kiln for testing schedules, trying new compatible glass combinations, or firing small one-offs without tying up the big kiln.
For a kiln you'll fire often, the Solid State Relay (SSR) is a worthwhile upgrade. It gives you tighter temperature control, longer element life, and quieter cycling, and tends to outlast the standard mechanical relay by a wide margin. The standard Orton AF3-Key controller gets the job done for occasional use, but for daily firings consider upgrading at checkout to the Orton AutoFire 12-Key or the TAP Smart Touchscreen with Wi-Fi.
