Orton Pyrometric Bar Cones

A Pyrometric Bar Cone is a rectangular-shaped pyrometric device used to measure heatwork in kilns, primarily with Orton Kiln Sitters. Unlike standard pyrometric cones, bar cones are designed to bend and trigger an automatic shutoff mechanism, ensuring precise kiln control. They provide accurate firing results by accounting for both temperature and time, helping to prevent under- or over-firing in ceramics, pottery, and industrial applications. Available in various cone numbers, they help maintain consistent glaze and clay maturation.
