An All-Fiber Kiln Built for Speed. Multiple Firings a Day, On a Standard Outlet.
The AF3P Bonnie Glo is built around a single idea: fiber fires fast. 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. That means quick heat-up, quick cooldown, and the ability to run multiple firings in a single day. For glass painters and fusers working through batches of small pieces, that's a real workflow advantage.
The interior is 15" wide by 5" deep, with 0.5 cubic feet of working space. Long and shallow, which is a useful footprint for glass painters working on strips of work, smaller fused panels, or a row of test pieces in a single firing. Fires up to 1700°F, the right range for full fuse, tack fuse, and painting work.
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.
Included with every order
All-fiber kiln chamber, stationary stand, 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 is a specialty kiln with a clear purpose. Here's how to tell if it's right for you.
✓ Glass painters firing pieces throughout the day
If you paint glass and need to fire pieces between layers, an all-fiber kiln with fast cooldown is what makes that workflow possible. No more waiting overnight between firings.
✓ Fusers doing small-batch production
Multiple firings per day means you can move through a batch of small pieces in a single studio session instead of stretching it across a week.
✓ 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 is a smart second kiln for testing schedules, trying new compatible glass combinations, or firing small one-offs without tying up the big one for a single piece.
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 caster stand is also worth a look if you'll be moving the kiln around the studio or tucking it away between firings.
