Cone 10
25 cones per box
Pyrometric cones 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 occurred during firing. Cones are made from carefully controlled compositions and they bend in a repeatable manner (over a relatively small temperature range- less than 40ºF). Small (junior) cones are used in a Kiln-Sitter™.
