Ceramic Cone Temperature Guide

The actual bending temperature depends on firing conditions.

Ceramic cone temperature guide.

1566 f 850 c this range is usually used for luster glazes and very low firing overglazes. 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. Ware must be fired at least once at a higher temperature first in order for the clay body to mature. 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. Ware and glaze types. From cone 022 approx. Although cones do not actually measure temperature cone bending behavior and temperature are related.

To describe a property of glaze or clay. Temperatures shown are for specific mounted height above base. 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.

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

As discussed above the equivalent cone temperature depends upon how fast one gets to it. Once the appropriate cones are selected excellent reproducible results can be expected. This is a beautiful cone 6 glaze or i wish we had real cone 10 porcelain this is the most frequent use of the. 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.

Please note that the cone chart gives 3 different temperatures for each cone number.
