Are Cress kilns good?

Cress Kilns come in different shapes, mostly square and octagonal. The octagonal shape allows you to fit more ware into the kiln. It is also more heat efficient and usually provides more even distribution of heat throughout the kiln. They are also usually more expensive as they are a more difficult kiln to build.

How much does a kiln cool per hour?

I recommend a cooling rate of about 200° per hour through quartz inversion (1063°F). Crystal growth in some glazes can vary depending on the rate of down firing—a fast cool results in a glossy surface, while a slow cool goes matte. The crystals creating the satin surface are happening between 1900°F and 1450°F.
