    Abstract: A smooth surface heating apparatus is provided having a heat spreader plate of high thermal conductivity coated, at least on its upper surface, with a glass-ceramic material containing a predominant crystalline phase of lithium disilicate in a glassy matrix and having a coefficient of expansion in the range of 80-120x10 7 per DEG C. An insulated electrical resistance heating element and a reinforcing member are attached to the underside of the heat spreader plate. A reflector pan is provided beneath the heating element to direct the heat in an upward direction.
