Finished pots in glaze kiln

Potters don’t bake pottery, they fire it. Most potters fire their pottery twice. The first firing is called the biscuit firing. The biscuit Firing is the process that converts clay into a hard ceramic substance. The second firing is the glaze firing. Firing temperatures range from 1877f/1025c to 2480f/1360c depending on clay and glaze type. Earthenware is fired to the lower temperatures while stoneware and porcelain are fired to the hotter temperatures.
A kiln is the structure used by potters to fire their work. There are many types of kilns which are determined by the type of fuel used(electric, wood, oil or gas) or the name of the ware fired in them (Raku or salt glazed). The length of time need to fire a kiln varies as well. Electric fired earthenware is usually fired for around 12 hours and allowed to cool for 24 hours. Wood fired stoneware can be fired for 5-7 days(24/7) in an anagama kiln and need another week to cool. Then there are any number of other options in-between! Temperature, clay, and fuel are just some of the variable involved in firing ceramics. There are many other factors which will be addressed on this page in the future.
