Ceramic Firing Temperatures Cone

Mid fire earthenware should be fired between cone 2 and cone 7.

Ceramic firing temperatures cone.

Ware and glaze types. Mostly yellow with a hint of orange. Ware must be fired at least once at a higher temperature first in order for the clay body to mature. Thus pyrometric cones give a temperature equivalent.

Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. This is a mechanical device that shuts off the kiln when the temperature inside is sufficient to cause the cone to deform under the weight of the kilnsitter rod. After firing a kiln a simple glance at the cone can tell if the firing was sucessful. 1566 f 850 c this range is usually used for luster glazes and very low firing overglazes.

Cone temperature conversion chart. 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. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. 1112 f 605 c to cone 013 approx.

From cone 022 approx. This is the most common temperature range for industrial ceramics. The small and bar cones are mainly used in the kiln shut off device called the kilnsitter.
