It takes the same 26-inch solid round shelf and the same 18\" x 18\" maximum piece as its taller sibling, in an 11-inch chamber at 3.91 cubic feet — which is the right trade if your work is flat. Large bowl slumps, platters, long panels, a full shelf of tiles. The walls and lid are 3-inch brick, which Jen-Ken rates at about 20% more insulation than a standard wall, and that shows up as a steadier anneal hold rather than a faster climb. Elements fire top and side together so a 26-inch shelf fuses evenly out to the rim. Lid lifters and the 12-button controller are included, and it runs on a 240V 36-amp circuit — nine amps less than the 15-inch build, which can be the difference between calling an electrician and not.\u003c\/span\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"d-glance\"\u003e\n  \u003cdiv class=\"d-gi\"\u003e\n\u003cspan class=\"d-gl\"\u003eMax Temp\u003c\/span\u003e\u003cspan class=\"d-gv\"\u003e1,700°F\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-gi\"\u003e\n\u003cspan class=\"d-gl\"\u003eChamber\u003c\/span\u003e\u003cspan class=\"d-gv\"\u003e28\" x 11\"\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-gi\"\u003e\n\u003cspan class=\"d-gl\"\u003eCapacity\u003c\/span\u003e\u003cspan class=\"d-gv\"\u003e3.91 cu ft\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-gi\"\u003e\n\u003cspan class=\"d-gl\"\u003ePower\u003c\/span\u003e\u003cspan class=\"d-gv\"\u003e240V · 36A\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"d-section\"\u003e\n  \u003cdiv class=\"d-sh\"\u003eWhat’s included\u003c\/div\u003e\n  \u003cdiv class=\"d-grid2\"\u003e\n    \u003cdiv class=\"d-cell\"\u003e\n\u003cspan class=\"d-cn\"\u003eOrton AutoFire 12-key controller\u003c\/span\u003e\u003cspan class=\"d-cd\"\u003eThe 12-key AutoFire rather than the 3-button — preprogrammed schedules plus blank user programs.\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"d-cell\"\u003e\n\u003cspan class=\"d-cn\"\u003e3-inch brick walls and lid\u003c\/span\u003e\u003cspan class=\"d-cd\"\u003eJen-Ken's figure is around 20% more insulation than their standard wall.

Nothing in the chain is undersized. It is still a dedicated run — have a licensed electrician confirm it against local code before delivery, and note Jen-Ken's own caveat that more than about 30 feet from the panel may need the next heavier gauge.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eHow big a piece will it take?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eJen-Ken's own figures are a 26-inch solid round shelf or work up to 18\" x 18\" square — the same as the taller 28-E.

Jen-Ken's number is about 20% more insulation, and on glass that matters less for reaching temperature than for holding one — an anneal soak on a thick piece is a long, slow hold, and a better-insulated chamber does it with less element cycling. It also adds weight, which is part of why the crate is 325 lbs.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWill it fire clay?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eNo. 1,700°F is a glass ceiling, not a ceramic one.
