Large 23″ Stackable Electric Kiln — 7 cu ft, Cone 10
Model
2327HE
Max Temp
Cone 10 · 2350°F
Chamber
23⅜″ × 27″ · 7 cu ft
Warranty
1-Year
The Olympic 2327HE is the deep, high-fire member of the 23″-wide stackable line — a 23⅜″ × 27″ chamber holding a full 7 cubic feet. This is a production kiln: enough capacity for a busy studio's glaze cycle, a classroom's worth of student work, or tall sculptural pieces that won't fit anywhere else.
Built with 3″ firebrick and rated to cone 10 (2350°F), it fires porcelain and high-fire stoneware without strain. The thicker brick also insulates better, so a chamber this size holds heat efficiently and cools gently — which matters both for glaze development and for how long your elements last.
A lid lift assist comes standard, as it does on every 23″ and 28″ Olympic stackable — essential on a lid this size. And because the body comes apart into sections, a 7 cubic foot kiln can still be carried into a basement studio or through a standard doorway one ring at a time.
Included with every order
Bartlett KilnStar digital controller, lid lift assist, pilot light, 8″ metal stand, stainless steel jacket, observation plugs with peephole plugs, full instruction manual, and a 1-year limited kiln warranty through Olympic.
Popular options include the Genesis touchscreen controller (delay start, preheat, cone offset, skip step), 2- or 3-zone control, automatic lid shut-off, castors, a Type S thermocouple, dual media, and 480V or 3-phase wiring. Give us a call and we'll help you spec it.
A note on lead time: Olympic kilns are made-to-order at their Flowery Branch, Georgia facility. Give us a call before ordering and we'll confirm current production estimates.

Not sure if this is the right kiln for you?
Give us a call. We'll talk through your space, your electrical service, and the work you want to fire, and help you land on the right kiln.
The Olympic 2327HE is exactly the workhorse I needed for my production ceramic studio. We're firing cone 6 and cone 10 glaze loads multiple times a week and the kiln hasn't missed a beat. The 7 cubic foot interior fits our shelf configuration perfectly. Pro Kiln Supply answered every question I had during the research phase and the freight delivery was coordinated without any issues on their end.
