Firing Supplies

Standard (Large) Pyrometric Cones allow users a practical method to monitor the heatwork (the effect of temperature and time at temperature) inside their kiln.

Self-Supporting Cones are the most accurate and easiest to use witness cones available.

Small Cones are commonly used in the Kiln-Sitter®. The tapered shape allows some flexibility to adjust shut-off by placing the thinner or thicker portion of the cone under the sensing rod.

Cone Plaques (holders) are designed to hold the cones at exactly the right angle so that they bend at the correct amount of heat work giving you accurate information about your firing.
