A 7.2 Cubic Foot Oval Brick Kiln. Built for Studios That Fire Big and Fire Often.
The AFG Oval 13 is a serious workhorse. With 24" x 39" x 13" of interior space and 7.2 cubic feet of capacity, you can fuse two large pieces side by side, slump a small sink, or load up a full classroom's worth of student work and fire it all in one go. The oval shape gives you a long, generous footprint without wasting the corners you'd never use in a square kiln.
This is a full brick kiln, which matters more than people sometimes realize. Brick holds heat. Brick cools slowly. And brick gives you the kind of long, even thermal mass that takes the stress out of annealing. With a brick chamber this size, you really don't have to fight the kiln to get your work to anneal properly. It just does.
The Oval 13 maxes out at 1700°F, plenty for full fuse, tack fuse, slumping, and draping. It ships standard with the Orton AutoFire 12-Key controller, a reliable P-I-D controller that supports up to 4 custom programs and holds its memory through power loss so a firing can resume right where it left off. If you want more storage, easier programming, or remote monitoring, you can upgrade at checkout to the TAP Smart Touchscreen or the Orton AutoFire Slide.
Included with every order
Stationary stand built for the kiln's weight and shape, Orton AutoFire 12-Key controller, and the manual. Add the furniture kit at checkout for two 21" x 18" D-shelves, a posts assortment, and kiln wash.
Who Is This Kiln For?
The Oval 13 is built for studios that need real production capacity. Here's how to tell if that's you.
✓ Studio classrooms and teaching spaces
7.2 cubic feet means you can fire a whole class's worth of student pieces in a single run. Less waiting, more teaching, and predictable turnaround for the next session.
✓ Production fusers working at scale
Two large pieces at a time, or a full shelf of smaller production work. If you're filling orders and want to cut the number of firings in half, this is the kiln that does it.
✓ Slumpers working on sinks, platters, and large vessels
The oval footprint and 13" of depth handle slumping work that won't fit comfortably in a square kiln, including small sinks and oversized serving pieces.
✓ Artists who want forgiving anneals
Full brick construction gives you the thermal mass for slow, even cooldowns. If you've struggled with stress fractures or annealing issues in lighter-built kilns, brick takes that worry off the table.
If you're going to keep this kiln for a while, two upgrades pay for themselves quickly. The Solid State Relay (SSR) gives you tighter temperature control, longer element life, and quieter operation. And the Orton Vent Master downdraft vent pulls fumes safely outside, improves temperature uniformity in the chamber, and extends element life by adding oxygen during firing. Both are worthwhile investments on a kiln this size.
