    what is acone?a guide to pyrometric cones and kilns

    Pyrometric cones are designed to deform at certain moments during a firing. This deforming action allows the kiln to shut off automatically at the proper point (as in the case of the mini bar and Kiln Sitter) or simply to record what happened during the firing (as in the case of the witness cone)
