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 the cone tip sags until it reaches a point level with the base indicating the kiln has properly fired. The cones can also be used in a kiln sitter with equally accurate results. 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 06 which bends at an approximate temperature of 1830° F, depending on firing conditions.

My fault, searched for bars, not cones, and this came up. Picture is misleading as they show the conjoined cones on their side, which makes it look like bars. Will be able to use these in my kiln sitter, but would’ve preferred bars, as these aren’t easy to break apart without destroying them. Wish Amazon carried the bars instead!

The cones work great but they come two joined together. I tried breaking apart with my hands that failed but using a dull knife they separated easily

the cones come as wo cones which need to be separated before using. It was very difficult for me and broke quite a few trying. the shipper however did everything right, fast and well packed. I'm sure they are not responsible for Orton cones coming that way.

Great cones but for my application they were not correct.

These cones work perfectly in my kiln for making my ceramics. I have recently started this new projectand am having fun doing it.
