Abstract: An electrically conductive non-stick coating for a substrate for making electrical contact with external materials comprising a layer of conductive material adherently deposited on the substrate and a superposed layer of organic non-stick material on said conductive layer being chemically bonded thereto.

Abstract: Aluminum-coated glass-ceramic cookware of improved performance and durability is provided by a process comprising selecting a glass-ceramic vessel of specified strength and expansion characteristics, preheating the surface of the vessel to a temperature in the range of about 120.degree.-600.degree. C., flame-spraying molten powdered aluminum metal onto the surface of the vessel, optionally heat-treating the thus-coated vessel to provide an aluminum metal coating of excellent adherence and good thermal conductivity thereon, providing the aluminum coating with a film of phosphoric acid and heating said aluminum coating and film to a temperature at least sufficient to decompose the phosphoric acid. A supplemental oxide film may also be applied to protect the aluminum metal coating.
