Orton Pyrometric Witness Cones

Orton Pyrometric Cones are precision heatwork measurement tools used in ceramic, pottery, and industrial kilns to ensure accurate firing.

Available in Large Regular Base (LRB) and Small Regular Base (SRB), they provide reliable temperature monitoring . These cones visually indicate when the correct amount of heat energy has been absorbed, helping prevent under-firing or over-firing.

Essential for glaze maturity, clay vitrification, and quality control, Orton Pyrometric Cones are trusted by potters, ceramic artists, and manufacturers for consistent firing results.
