Abstract
A method of estimating a temperature of a material being heated is described. The method may comprise supplying electrical power to a heating element in dependence on a measured temperature, calculating a rate at which the amount of electrical power supplied changes over time, comparing the calculated rate with a plurality of known values in order to determine the value of a parameter relating to thermal properties of the material being heated, and calculating an estimated temperature based on the determined value of said parameter. In some embodiments, the method may further comprise detecting a drop in temperature of the material being heated, by detecting a change in the calculated rate at which the amount of electrical power supplied changes over time.
