Ceramic Firing Temp

Each ceramic glaze should be fired to a specific temperature range.

Ceramic firing temp. Mid fire earthenware should be fired between cone 2 and cone 7. The ware is returned to the kiln for a very low temperature firing in order to fuse the overglazes. When potters talk about ceramic firing ranges they are usually referring to the three most common. First it is important to know that the maximum cone rating of a stoneware or porcelain clay is the temperature at which it vitrifies.

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. The fancy name for this is vitrification or the ceramic chemistry that transforms a clay body into a hard non crystalline glass. Low fire mid range and high fire ranges.

This is the most common temperature range for industrial ceramics. Clay bodies have ranges of temperature that they can be fired to. This is the hardening tightening and finally the partial glassification of the clay. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240.

Mostly yellow with a hint of orange. We get many questions about clay firing temperatures. People want to know if they can fire a certain clay to a certain cone. For success a potter must know their glazes temperature ranges at which they become mature.

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.
