Ceramic Firing Temperature Chart

Rates of climb change per firing as do temperature equivalents.

Ceramic firing temperature chart.

13 to 42 used for firing industrial products up to 3659f 2015c. Stoneware glaze some decals fire to cone 10. Very high fire porcelain. Cone 10 13 range 2381 2455 f 1305 1346 c.

Mid fire earthenware should be fired between cone 2 and cone 7. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240. Trapped water causes clay to explode so keep the kiln below 100ºc until all water has evaporated. Mostly yellow with a hint of orange.

Pottery and ceramic firing chart fact 1. Bodies shrinks suddenly at 220ºc. A common temperature range for industrial ceramics. 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.

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. This means that it must be baked in a special furnace called a kiln to a minimum temperature of about 1112 f. If fired at too low a temperature the glaze will not mature.

Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. Kiln firing chart temperature c f 1400 2552 1300 2372 1200 2192 1100 2012 1000 1832 900 0111652 800 1472. Here is the orton cone temperature chart. Ware and glaze types.

The temperature equivalent range is approximately 2175 2345f 1180 to 1340c. Fast cooling at this temperature causes ware to crack. Make you sure you use the correct firing temperatures for the clay and glazes you have used. A body glaze layer that forms between the clay body and glaze.

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. Water boils and converts to steam at 100ºc. Download complete orton cone wall chart here. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery.

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. Each ceramic glaze should be fired to a specific temperature range. Cone temperature conversion chart. The ramp rate is usually measured in degrees per hour.
