  • Patent number: 4458875
    Abstract: The apparatus consists of a vessel that is transparent to microwaves, an inner coating of material that is heated by microwaves and a coating inside that that will reflect microwaves.In use the user allows his mold substance to set in the ordinary way. When he desires to release his moldable from the molded substance he applies microwaves to the outside of the vessel. The waves pass through the outer transparent wall and heat the inner coating. Conductivity of heat causes the surface of the molded object to be heated, to liquefy and release from the mold. The innermost layer of reflective substance prevents the microwaves from penetrating into the molded object and heating the whole molded object.What is new is an apparatus that will permit the user to quickly and conveniently release a molded object from a mold without any risk that he will heat and destroy portions of the molded object.
