Abstract
A method for sensing overheating of a food container positioned on a glass ceramic cooking hob, for example during the preparation of a food contained in said container, electrical heating elements being provided for predefined regions of said hob. The method includes continuously measuring the variation in temperature of the region of the cooking hob during the activation of a corresponding heating element on which the container is positioned on the hob. The method further includes halting said activation when said temperature undergoes a sudden increase relative to a temperature value maintained substantially constant with time during activation of the heating element.
