Abstract

A method and apparatus are provided for monitoring in situ the transformation of some fraction of a starting material to another material during the course of a thermal treatment. The starting material is heated to a preselected temperature and its resistivity is measured. A signal is transmitted to an actuator, which indicates cooling of the material when a preselected resistivity or change therein is detected.
