Large Pyrometric Cones allow users a practical method to monitor the heatwork (the effect of temperature and time at temperature) inside their kiln. Today they are used by quality conscious manufacturers who want a visual indication of the heatwork in locations throughout their kiln.
Large cones must be mounted in a plaque with the cones mounted at 8 angular degrees. Plaques can be made by hand or purchased (see cone plaques in our product list).
