About this item

  • The number of this cone is 03 which bends at an approximate temperature of 2014° F, depending on firing conditions
  • Pyrometric 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 100 years and Orton has the history and experience to provide the very best product
