Abstract: The present invention provides a composition for use in forming a porcelain enamel coating having a metallic appearance. The composition according to the invention preferably includes a low shear blend of a glass component and metal particles such as aluminum, nickel, copper and stainless steel. The glass component includes at least one glass frit that fuses at a temperature of less than about 600° C. Upon firing at a temperature of from about 535° C. to about 600° C., the composition forms a vitreous porcelain enamel coating that has a metallic appearance, which through the incorporation of various optional pigments and/or mill additions, can range from a bright brushed nickel or stainless steel appearance to a matte dark metallic finish.

Abstract: The present invention provides a new and useful nonstick coating for use on pure aluminum, alloys of aluminum, or aluminized steel surfaces. A nonstick coating according to the present invention includes a ceramic substrate disposed on an aluminum surface and a fluorocarbon polymer coating disposed on the ceramic substrate. The ceramic substrate, prior to firing, includes at least two layers: a first or bottom layer applied to the aluminum surface including an enamel ground coat; and a second or top layer applied over the enamel ground coat layer including a blend of one or more glass frits, non-ceramic refractory particles, and non-vitreous inorganic oxide particles. Upon firing, the ceramic substrate includes a continuous layer of vitreous enamel that is bonded to the aluminum surface. The exposed surface of the ceramic substrate has a micro-rough texture that is enriched with bonding sides for binder resins used in a fluorocarbon polymer primer layer.
