Ceramic Cone Plaques hold 3 Large Cones at the proper firing angle required for the proper measurement of heat work. These plaques are rated to Cone 12+ and are reusable. Applying a thin coat of kiln wash to the plaques helps to prevent the cones from sticking. Witness Cones should be used in every firing to confirm that the proper heat work was achieved. Show more
