摘要： A potter's oven includes an electrical heating element for controlling the temperature in the oven. Power to this heating element is controlled by a bimetallic switch and an electrically energized heater therefor and the percentage of power supplied to the oven heating element is controlled in dependence upon the value of resistance in series with the heater for the bimetallic switch. The value of this resistance is increased in stepwise fashion under control of at least one sensor which determines the outside wall temperature of the oven, the temperature at which the sensor responds being chosen to cause the temperature inside the oven to reach a predetermined value and to hold such value for a predetermined time.
