Cones

Shop pyrometric cones and kiln firing supplies at GlazeQueen. Pyrometric cones measure heat-work—the combined effect of time and temperature during a ceramic firing—and help potters verify that their clay and glazes have received the proper amount of heat-work. Our selection includes Orton self-supporting cones, large cones, small cones, cone bars and cone holders for pottery and ceramic kilns. Use witness cones to verify firing results and monitor the performance and consistency of your kiln.
