An efficient method for using a periodic kiln to heat ceramic material to a state of maturation, and the apparatus for carrying out the method, duplicate the action of pyrometric cones. In a microcomputer, data is stored describing the relationship between rates of temperature increase and deformation temperatures for several numbered pyrometric cones. The kiln operator selects the cone number for use in the firing operation and then activates both the apparatus and the kiln's heating elements. Using a thermocouple, the microcomputer periodically measures kiln temperature and calculates the average rate of temperature increase inside the kiln (the rate need not be controlled). The rate is then used, in conjunction with the stored data, to determine the temperature at which the ceramic material will have matured. If the present temperature in the kiln is greater than or equal to this maturation temperature, the microcomputer sounds an alarm or shuts off the heating elements.
