Abstract An electric heating device, which may be used to heat rocks that may function as a source of stored heat or may also be used as a play oven or play stove, comprises a paper box lined on the interior with reflective foil. The box is formed with ventilation openings in its side walls and includes a removable top provided with an opening in which is seated an aluminum foil tray in which the object to be heated is placed. Positioned within the box below the tray is an electric light bulb for providing heat. The light bulb is seated in a socket carried by a wire support. The wire support is a single piece of wire formed with a pair of base legs resting on the box bottom and an inverted V portion extending upwardly from the base legs and formed with a loop above the V for accommodating the socket stud.
