Ceramic Firing Temperatures Cone

Ceramic firing temperatures cone.

The cones often used in sets of three are positioned in a kiln with the wares to be fired and provide a visual indication of when the wares have reached a required state of maturity a combination of time and temperature. 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. This is the most common temperature range for industrial ceramics. 1112 f 605 c to cone 013 approx.

Ware must be fired at least once at a higher temperature first in order for the clay body to mature. Thus pyrometric cones give a temperature equivalent. After firing a kiln a simple glance at the cone can tell if the firing was sucessful. Mid fire earthenware should be fired between cone 2 and cone 7.

Cone temperature conversion chart. This is a mechanical device that shuts off the kiln when the temperature inside is sufficient to cause the cone to deform under the weight of the kilnsitter rod. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240. 1566 f 850 c this range is usually used for luster glazes and very low firing overglazes.

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. Mostly yellow with a hint of orange.
