From cone 022 approx.
Ceramic temperature cones.
Because cones are made from carefully formulated ceramic compositions they bend reliably at specific temperature ranges.
Calculate kiln cone temperature for cone 022 to cone 10 based on the kiln s heating rate.
For example cone 06 indicates a temperature range of approximately 1800 1850f.
1566 f 850 c this range is usually used for luster glazes and very low firing overglazes.
Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years.
Cone 10 13 range 2381 2455 f 1305 1346 c.
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 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.
1112 f 605 c to cone 013 approx.
A body glaze layer that forms between the clay body and glaze.
Stoneware glaze some decals fire to cone 10.
Although cones do not actually measure temperature cone bending behavior and temperature are related.
Ware must be fired at least once at a higher temperature first in order for the clay body to mature.
Your ceramic ware provider can provide guidance on which cone to fire to for your specific ware.
Use the cone comparison calculator to see the temperature difference between cones.

Pyrometric cones are designed to deform at certain moments during a firing.
A cone 01 needs less heat treatment than cone 1 and cone 020 needs less than 019.
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.
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.
Pyrometric cones measure heatwork the effect of time and temperature.
Thus pyrometric cones give a temperature equivalent.
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.
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.
Very high fire porcelain.
Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials.
