Ceramic Cone Temperatures

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials.

Ceramic cone temperatures.

Cone 022 is the lowest melting cone and requires the least amount of heat to deform or bend. During firing a cone softens and melts as it is heated. Cone temperature conversion chart. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years.

Thus pyrometric cones give a temperature equivalent. 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. Ware and glaze types. 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.

Please note that the cone chart gives 3 different temperatures for each cone number. As discussed above the equivalent cone temperature depends upon how fast one gets to it. Cones used on the kiln shelf bend due to the effects of gravity pulling the tip down. Cone numbers orton makes cones from cone 022 up to cone 42.

Stoneware glaze some decals fire to cone 10. Pyrometric cones will be the first to let you know your ceramic firing is under control or that subtle changes.
