Ceramic Firing Temperatures Cone

From cone 022 approx.

Ceramic firing temperatures cone.

Stoneware glaze some decals fire to cone 10. The small and bar cones are mainly used in the kiln shut off device called the kilnsitter. Thus pyrometric cones give a temperature equivalent. 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. 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. 1112 f 605 c to cone 013 approx.

1566 f 850 c this range is usually used for luster glazes and very low firing overglazes. Ware must be fired at least once at a higher temperature first in order for the clay body to mature. 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. This is the most common temperature range for industrial ceramics.

Mid fire earthenware should be fired between cone 2 and cone 7. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials. After firing a kiln a simple glance at the cone can tell if the firing was sucessful.
