The Kiln Room

The full Jen-Ken range explained: why the pottery line is cone 8 and not cone 10, how the Ceram-a-Glass switch lets one kiln fire both clay and glass, and specs and prices for every pottery, glass, fiber and vertical knife kiln.

Cone 6 is 2232°F and cone 10 is 2345°F — a 113-degree gap that shows up in element life, amps, warranty terms and price. We compare every pottery line we carry, with verified manufacturer cone ratings and current prices, and explain why the best answer for most potters is a cone 10 kiln fired to cone 6.

The full Cress range explained: what E vs ET actually means, what the three-year warranty really covers, and specs and prices for all 40 ceramic, front-loading and glass models.
