A Bigger Hybrid: Ceramics and Glass in 9 Cubic Feet
The Jen-Ken Ceram-A-Glass JK Squared 22" is the larger version of our hybrid Ceram-A-Glass series, built on the JK Squared platform. Same big idea (one kiln, two firing modes, full studio coverage), but with a 27" x 22" chamber and 9 cubic feet of capacity. That's a full cubic foot more than the standard Ceram-A-Glass 2822, which means real room for full sized work in both disciplines.
In glass mode, the kiln tops out at 1700°F. The top elements give the glass a uniform blast of radiant heat from above, while some of the side coils help bring the kiln to temperature evenly. That's exactly the heating pattern glass needs for full fuse, slumping, draping, and casting work.
In ceramic mode, the kiln reaches 2150°F, which covers cone 6 mid fire stoneware, all your low fire work, glaze firings, and bisque. The side coils carry the load like a traditional ceramic kiln to give you the even chamber heat ceramics need.
Runs on standard 240V / 45 amp single phase NEMA 6-50 plug, 10,800 watts. No three phase electrical needed.
Need 2300°F? Inquire before ordering
The Ceram-A-Glass JK Squared can be ordered with a manual bypass option that lets it reach 2300°F (cone 8). This is a build option, not something you can switch on later. If you need cone 8 capability, give us a call before you order so we can spec the right configuration for your studio.
Who Is This Kiln For?
The Ceram-A-Glass JK Squared 22" is built for a specific kind of artist. Here's how to tell if that's you.
✓ Mixed media artists working at scale
If your work crosses ceramics and glass and you've been wanting more room than a standard hybrid kiln offers, the 9 cu ft chamber lets you fire bigger pieces in both disciplines.
✓ Teaching studios with mixed programs
One kiln supports both ceramic and glass classes, with enough capacity to handle group projects and full classroom firings. Way easier on scheduling, space, and budget than running two separate kilns.
✓ Working studios that want hybrid flexibility
If you sell in both ceramic and glass markets but don't want to commit space and electrical to two large kilns, this one delivers both disciplines on one footprint and one plug.
✓ Artists scaling up from a smaller hybrid kiln
If you've outgrown a smaller dual purpose kiln and need more capacity but still want both modes, this is the bigger sibling that lets you take on larger work.
You'll pick your digital controller at checkout. The Orton AutoFire 12 Key handles both ceramic cone programs and custom glass schedules. The AutoFire Slide adds a touchscreen and stores 35 firing schedules, which is great when you're switching between ceramic and glass programs often. And the TAP Smart Controller with Wi Fi lets you run firings from your phone or tablet, with virtually unlimited program storage for both disciplines.

A heavy duty stand sized for this kiln, the full operator manual, kiln wash to get you started, a solid state relay (SSR) for tighter temperature control and longer element life, a 2 year limited warranty through Jen-Ken, and free freight shipping to the US Lower 48.
