Temperature Of Ceramic Cones

This deforming action allows the kiln to shut off automatically at the pr.

Temperature of ceramic cones. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. It is important not to confuse the lower maturing cones and bars whose numbers begin with an 0 with the higher cones and bars not containing this prefix. Pyrometric cones are designed to deform at certain moments during a firing. Although cones do not actually measure temperature cone bending behavior and temperature are related.

Stoneware glaze some decals fire to cone 10. Ceramic ware is most often fired to a cone as opposed to a temperature. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. Pyrometric cones measure heatwork the effect of time and temperature.

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.

A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019. Your ceramic ware provider can provide guidance on which cone to fire to for your specific ware.
