The handle itself is made of low carbon steel, and will have a plastic grip attached to it that is comfortable to grasp. Before selecting a plastic, it is necessary to have information on the temperature of the carbon steel handle. The carbon steel handle can be considered as a rod 11 mm in diameter and 45 mm long. When being used over a stove burner, the ambient temperature T∞ is 30 oC, and the temperature at the base of the handle reaches T0 = 100 oC.
