## Description

Pyrometric SRB04 Cones are used on a shelf inside a kiln or in a kiln sitter to determine when a firing is complete, if the kiln provided enough heat or if there was a problem during the firing. Orton cones are made from carefully controlled compositions so that they bend in a repeatable manner over a very small temperature range. When used in a cone holder or sitter, the cone tip sags until it reaches a point level with the base indicating the kiln has properly fired. Cones have been used in ceramic firings for more than 130 years and Orton has the history and experience to provide the very best product. The number of this cone is 04 which bends at an approximate temperature of 1940° F, depending on firing conditions.
