Claims11
A method of making an article of cookware having a cooking surface which comprises a multi-layer, non-stick fluoropolymer coating on a substrate which coating minimizes sticking by food residues and which is heat resisting by being stable at temperatures above 300.degree. C., wherein the multi-layer fluoropolymer coating comprises (1) a fluoropolymer primer coating adhered to the substrate, (2) a non-stick, heat-resisting, light-transmitting fluoropolymer topcoat coating, and (3) at least one optional fluoropolymer intermediate coating, said primer coating or said at least one fluoropolymer intermediate coating when it is present, having a first color or darkness, said method comprising;
- spraying at least two applications of globules as a discontinuous fluoropolymer coating onto the primer coating or optional at least one fluoropolymer intermediate coating when it is present, said globules having at least one color or darkness which is visibly different than said first color or darkness in said primer coating or said optional at least one fluoropolymer intermediate coating to which said discontinuous coating is applied as seen through said topcoat, with a first application of globules covering 30-80% of an area of said primer coating or said optional at least one fluoropolymer intermediate coating to which said first application is applied and a second application of globules covering 20-45% of the same area as said first application, with the second application covering at least 5% less area than the first.
