Ceramic Firing Temperature Chart

A body glaze layer that forms between the clay body and glaze.

Ceramic firing temperature chart.

The firing schedule for bisque firing is extremely important. This means that it must be baked in a special furnace called a kiln to a minimum temperature of about 1112 f. Bodies shrinks suddenly at 220ºc. If fired at too low a temperature the glaze will not mature.

The ramp rate is usually measured in degrees per hour. Very high fire porcelain. Water boils and converts to steam at 100ºc. Mid fire earthenware should be fired between cone 2 and cone 7.

Make you sure you use the correct firing temperatures for the clay and glazes you have used. The ware is returned to the kiln for a very low temperature firing in order to fuse the overglazes. Fast cooling at this temperature causes ware to crack. 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.

Cone 10 13 range 2381 2455 f 1305 1346 c. To become hard and glass like clay must be fired. 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. Mostly yellow with a hint of orange.

Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. The temperature equivalent range is approximately 2175 2345f 1180 to 1340c. This is the most common temperature range for industrial ceramics.

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. Stoneware glaze some decals fire to cone 10. Ware and glaze types. 13 to 42 used for firing industrial products up to 3659f 2015c.

Trapped water causes clay to explode so keep the kiln below 100ºc until all water has evaporated. Each ceramic glaze should be fired to a specific temperature range. Cone temperature conversion chart. A common temperature range for industrial ceramics.

Rates of climb change per firing as do temperature equivalents. Download complete orton cone wall chart here. Here is the orton cone temperature chart. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery.
