Ceramic Cone Temperatures

Pyrometric cones will be the first to let you know your ceramic firing is under control or that subtle changes.

Ceramic cone temperatures.

Stoneware glaze some decals fire to cone 10. 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. Cones used on the kiln shelf bend due to the effects of gravity pulling the tip down. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years.

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. Ware and glaze types. Pyrometric cones are used worldwide to monitor ceramic firings where consistent temperature is important to the quality of the final product being fired cones are used both in industry and by ceramic artists alike. Thus pyrometric cones give a temperature equivalent.

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china. Cone temperature conversion chart. Pyrometric cones measure heatwork the effect of time and temperature.

Cone numbers orton makes cones from cone 022 up to cone 42. Cone 022 is the lowest melting cone and requires the least amount of heat to deform or bend.
