Summary

A review of pyrometric cone behavior is given, with emphasis on how cone bending positions can be measured with a template and then used to provide data for a statistical process control program. The angular degrees the cone bends can be directly related to the temperature and the heat work the cone experienced during firing. Using nomographs prepared by Orton, temperature variations at different locations can be determined.
