Ceramic Firing Temperature Chart

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.

Ceramic firing temperature chart.

Water boils and converts to steam at 100ºc. Bodies shrinks suddenly at 220ºc. A body glaze layer that forms between the clay body and glaze. If the temperature goes too high the glaze will become too melted and run off the surface of the pottery.

The ware is returned to the kiln for a very low temperature firing in order to fuse the overglazes. 13 to 42 used for firing industrial products up to 3659f 2015c. Mid fire earthenware should be fired between cone 2 and cone 7. To become hard and glass like clay must be fired.

The ramp rate is usually measured in degrees per hour. Ware and glaze types. Cone temperature conversion chart. Rates of climb change per firing as do temperature equivalents.

This means that it must be baked in a special furnace called a kiln to a minimum temperature of about 1112 f. 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. Each ceramic glaze should be fired to a specific temperature range. 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.

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. 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.

A common temperature range for industrial ceramics. 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. Very high fire porcelain.

Stoneware glaze some decals fire to cone 10. Download complete orton cone wall chart here. Cone 10 13 range 2381 2455 f 1305 1346 c. Make you sure you use the correct firing temperatures for the clay and glazes you have used.

The firing schedule for bisque firing is extremely important. This is the most common temperature range for industrial ceramics. Pottery and ceramic firing chart fact 1. Trapped water causes clay to explode so keep the kiln below 100ºc until all water has evaporated.
