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. The number of this cone is 05 which bends at an approximate temperature of 1915° F, depending on firing conditions.

The cones come attached, two cone per block. 70% break or disintegrate when trying to separate them. The quality is low. We are looking for another manufacturer.We have not had a chance to try them yet. We have low expectations that the cones will function correctly in the kiln sitter.

They came soon enough, and will be ready when I fire again.

As a first-time kiln user, using these cones made firing really simple and easy. They have been working great for me, and Amazon has them for the cheapest price with free shipping I have found.
