Ceramic Cone Temperature Guide

Once the appropriate cones are selected excellent reproducible results can be expected.

Ceramic cone temperature guide.

Cone temperature conversion chart. To describe a property of glaze or clay. Ware must be fired at least once at a higher temperature first in order for the clay body to mature. 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.

Thus pyrometric cones give a temperature equivalent. This is a beautiful cone 6 glaze or i wish we had real cone 10 porcelain this is the most frequent use of the. As discussed above the equivalent cone temperature depends upon how fast one gets to it. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years.

The actual bending temperature depends on firing conditions. Although cones do not actually measure temperature cone bending behavior and temperature are related. Stoneware glaze some decals fire to cone 10. Ware and glaze types.

Temperatures shown are for specific mounted height above base. From cone 022 approx. 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. 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.

Please note that the cone chart gives 3 different temperatures for each cone number. Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china. A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019. 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.
