Pyrometric cones: Kiln temperatures for firing pottery

January 13, 2022


Kiln cones are geometrically shaped ceramic items of varying compositions designed to measure kiln temperatures. The different compositions are labeled from 022 to 10. The cone composition is used to measure heat absorption in a kiln.

Kiln firing at cone 3 temps is considered a โ€œmidโ€ firing range. The โ€œmidโ€ firing range is the most common range for potters to do a final glaze firing. A potterโ€™s finished pieces will be fired in this range.

High fire kiln cone temperature ranges

The following cones (8 and higher) are in a โ€œhighโ€ firing range. The temperature range is 1999ยฐ โ€“ 2052ยฐ.

In high heat, glazes go through a reduction process. The reduction process can change the texture of the clay, typically by making it more glass-like (vitreous).

This range is also commonly used in industrial firing. Think ceramic parts for your car or toilets. These items need to be fired at incredibly high temperatures. Either most commonplace kilns or their power sources canโ€™t reach cone ranges above 10.

Cone 8 temperatures

Kiln firing at cone 8 temps is considered a โ€œhighโ€ firing range. The โ€œhighโ€ firing range results in a glaze reduction process. This can change the texture of your glaze resulting in a more glass-like surface. โ€œHighโ€ firing ranges are also the most common range for industrial use (toilets, car parts, etc).

Cone 9 temperatures

Kiln firing at cone 9 temps is considered a โ€œhighโ€ firing range. The โ€œhighโ€ firing range results in a glaze reduction process. This can change the texture of your glaze resulting in a more glass-like surface. โ€œHighโ€ firing ranges are also the most common range for industrial use (toilets, car parts, etc).

Kiln cone 9 ranges in Fahrenheit

  • Kiln at 27ยฐF/Hour: 2235ยฐ

Cone 10 temperatures

Kiln firing at cone 10 temps is considered a โ€œhighโ€ firing range. The โ€œhighโ€ firing range results in a glaze reduction process. This can change the texture of your glaze resulting in a more glass-like surface. โ€œHighโ€ firing ranges are also the most common range for industrial use (toilets, car parts, etc).
