Ceramic Firing Temperature Chart

A common temperature range for industrial ceramics.

Ceramic firing temperature chart.

If fired at too low a temperature the glaze will not mature. Cone temperature conversion chart. The firing schedule for bisque firing is extremely important. Mostly yellow with a hint of orange.

A body glaze layer that forms between the clay body and glaze. Download complete orton cone wall chart here. Pottery and ceramic firing chart fact 1. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery.

This means that it must be baked in a special furnace called a kiln to a minimum temperature of about 1112 f. Ware and glaze types. Trapped water causes clay to explode so keep the kiln below 100ºc until all water has evaporated. For a bisque firing there will be no soak and the ramp the increase in which the kiln s temperature is changing should be very slow.

The ware is returned to the kiln for a very low temperature firing in order to fuse the overglazes. Average is cone 10 2381 f 1305 c cone 8 12 range 2305 22419 f 1263 1326 c a hard vitrified non absorbent clay body. Water boils and converts to steam at 100ºc. Very high fire porcelain.

Bodies shrinks suddenly at 220ºc. Cone 10 13 range 2381 2455 f 1305 1346 c. To become hard and glass like clay must be fired. This is the most common temperature range for industrial ceramics.

Mid fire earthenware should be fired between cone 2 and cone 7. Kiln firing chart temperature c f 1400 2552 1300 2372 1200 2192 1100 2012 1000 1832 900 0111652 800 1472. Rates of climb change per firing as do temperature equivalents. Here is the orton cone temperature chart.

Fast cooling at this temperature causes ware to crack. Stoneware glaze some decals fire to cone 10. They are useful in determining when a firing is complete if the kiln provided enough heat if there was a temperature difference in the kiln or if a problem occured during the firing. The temperature equivalent range is approximately 2175 2345f 1180 to 1340c.

Each ceramic glaze should be fired to a specific temperature range. The ramp rate is usually measured in degrees per hour. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240. All cones mature with time and temperature all temperature equivalents on this chart are based on a 270 f 150 c per hour rate climb using the large cone.
