A microwave energy source is associated with a heating medium containing a microwave energy absorption material so that the heating medium is heated to a high temperature when it is irradiated with microwave energy and produces infrared heat energy. The heating medium can be incorporated in a cooking dish or on the interior of a heat insulating housing.

A method of forming a painted object which comprises the steps of: placing in a microwave oven a closed container made of heat insulating material which is substantially transparent to microwave radiation, said container containing therein a glass or ceramic object having a surface decorated with a paint containing a metal oxide, the internal wall of said container being partially covered by a layer of microwave absorption material which is adhered to said internal wall and is disposed in directly confronting relationship only to the decorated surface of said object and is spaced therefrom, said microwave absorption material comprising a substance selected from the group consisting of powdered carbon and silicon carbide; and irradiating said container with microwaves whereby to heat said layer of microwave absorption material and thereby indirectly heat said object and oxidize and bake said paint on said decorated surface of said object without deforming said object.
