Ceramic cone temperature guide.

1112 f 605 c to cone 013 approx. Temperature equivalents for orton pyrometric cones c cone numbers 022 14 these tables provide a guide for the selection of cones. The actual bending temperature depends on firing conditions. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials.

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. From cone 022 approx. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. Please note that the cone chart gives 3 different temperatures for each cone number.

Thus pyrometric cones give a temperature equivalent. Once the appropriate cones are selected excellent reproducible results can be expected. As discussed above the equivalent cone temperature depends upon how fast one gets to it. Stoneware glaze some decals fire to cone 10.

Cone temperature conversion chart. As a potter you are guaranteed to hear and use the term cone on almost a daily basis generally potters use the term in three ways. Temperatures shown are for specific mounted height above base. A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019.

Ware and glaze types. 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. To describe a property of glaze or clay. 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.

Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china.
