Ceramic Firing Temp

When potters talk about ceramic firing ranges they are usually referring to the three most common.

Ceramic firing temp.

Low fire mid range and high fire ranges. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240.

Clay bodies have ranges of temperature that they can be fired to. The temperature needed to transform soft clay into hard ceramic is extremely high and is usually provided by a kiln. If fired at too low a temperature the glaze will not mature. First it is important to know that the maximum cone rating of a stoneware or porcelain clay is the temperature at which it vitrifies.

This is the most common temperature range for industrial ceramics. Mostly yellow with a hint of orange. We get many questions about clay firing temperatures. The glass phase that forms during the firing of a ceramic material can be thought of as the glue that holds the finished work together.

For success a potter must know their glazes temperature ranges at which they become mature. Mid fire earthenware should be fired between cone 2 and cone 7. This is the hardening tightening and finally the partial glassification of the clay. The fancy name for this is vitrification or the ceramic chemistry that transforms a clay body into a hard non crystalline glass.

You cannot fire pottery in a home oven because ovens do not get up to the high temperatures of more than 1 500 degrees fahrenheit that you need for firing clay.
