Ceramic Temperature Cones

A common temperature range for industrial ceramics.

Ceramic temperature cones. A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019. For example cone 06 indicates a temperature range of approximately 1800 1850f. Each cone type is assigned a number for example cone 06 and this number denotes a specific and fairly narrow temperature range. Because cones are made from carefully formulated ceramic compositions they bend reliably at specific temperature ranges.

Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. Calculate kiln cone temperature for cone 022 to cone 10 based on the kiln s heating rate. 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. Use the cone comparison calculator to see the temperature difference between cones.

Ware must be fired at least once at a higher temperature first in order for the clay body to mature. Kiln cone temperature calculator. 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. Your ceramic ware provider can provide guidance on which cone to fire to for your specific ware.

Ware and glaze types. Very high fire porcelain. Ceramic ware is most often fired to a cone as opposed to a temperature. This deforming action allows the kiln to shut off automatically at the pr.

Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. From cone 022 approx. Thus pyrometric cones give a temperature equivalent. Cone temperature conversion chart.

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. A body glaze layer that forms between the clay body and glaze. Pyrometric cones will be the first to let you know your ceramic firing is under control or that subtle changes. Although cones do not actually measure temperature cone bending behavior and temperature are related.

Stoneware glaze some decals fire to cone 10. Pyrometric cones measure heatwork the effect of time and temperature. Pyrometric cones are designed to deform at certain moments during a firing. Average is cone 10 2381 f 1305 c cone 8 12 range 2305 22419 f 1263 1326 c a hard vitrified non absorbent clay body.
