A Versatile 18" Round Glass Kiln for Home Studios
The Jen-Ken AFG 18-E 15" is a compact round glass kiln built for home and small studio glass artists who want serious capability without the size, weight, or electrical demand of a full production kiln. The interior is 18" round by 15" deep with 2.3 cubic feet of capacity. Round chamber means it's purpose built for circular pieces (platters, plates, bowls, decorative rounds), and the 15" depth gives you real vertical room for slumping into deeper molds.
What makes this kiln especially useful is the top and side firing design. The top elements give your glass the radiant heat that fusing needs from above. The side elements help bring the kiln to temperature evenly and support deeper slumping and draping work. Most glass kilns commit to one or the other. This one does both, which is genuinely rare at this size.
Fires up to 1700°F, plenty of headroom for full fuse, tack fuse, slumping, draping, and small casting work. Runs on 240V at 26 amps, 6,240 watts, with a NEMA 6-30 plug. That's a friendlier amp draw than most home studio kilns, so installation is easier on residential electrical.
Heads up: NEMA 6-30 plug, not NEMA 6-50
This kiln uses a NEMA 6-30 plug, which is a 240V 30 amp outlet. It's less common than the NEMA 6-50 most large kilns use. Some studios already have one (sometimes leftover from older electric dryers), but if you don't, your electrician can install a NEMA 6-30 line easily. Give us a call before you order if you want to confirm your setup works.
Included with every order
A heavy duty stand sized for this kiln, the full operator manual, the AF3P digital controller, a 2 year limited warranty through Jen-Ken, and free freight shipping to the US Lower 48.
Who Is This Kiln For?
The 18-E 15" is built for a specific kind of glass artist. Here's how to tell if that's you.
✓ Home studio glass artists ready for real 240V firing
If you've outgrown a 120V tabletop kiln and want serious capability at home, this delivers a real 240V working kiln at a friendly 26 amp draw.
✓ Artists making round platters, plates, and bowls
18" round chamber is purpose built for circular pieces. No wasted space, no compromised firings.
✓ Glass artists who fuse AND slump
Top firing for full fuse work, side firing for deep slumping and draping. The 15" depth handles deeper molds and tall forms most fusing kilns can't.
✓ Small studios with limited space and electrical
26 amps and 150 lbs make this manageable for studios that don't have room or panel capacity for a full size kiln, while still giving you real working capability.
The 18-E 15" ships standard with the Orton AutoFire 3 Key controller. For more flexibility on your firing schedules (especially useful if you're running varied fusing and slumping programs), upgrade at checkout to the AutoFire 12 Key, the touchscreen AutoFire Slide, or the TAP Smart Controller with Wi Fi.
