Small Cones are commonly used in the Kiln-Sitter—they are not used as witness cones. The tapered shape allows some flexibility to adjust shut-off by placing the thinner or thicker portion of the cone under the sensing rod.

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

Orton’s patented Self-Supporting Cones are the most accurate and easy to use witness cones available. Since the correct height and angle are built into the cone, reproducible firings can be achieved time after time.
