Self-Supporting Pyrometric Cones For Monitoring Ceramic Kiln Firings-Cone 6 (2 Pkgs/25)
These Self Supporting Orton Pyrometric Cones are used on a shelf inside a kiln to determine when a firing is complete, if the kiln provided enough heat or if there was a problem during the firing. This style of cone does not require a cone holder. These Orton  cones are made from carefully controlled compositions so that they bend in a repeatable manner over a very small temperature range. When the cone tip reaches a point level with the base it indicates it is 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. This offer includes two boxes of 25 cones each for a total of 50 cones. The  number of this cone is 6 which bends at an approximate temperature of 2291 degrees Fahrenheit depending on firing conditions.
