A non-stick surface comprising a porous, hard metal-ceramic coating such
as chromium oxide applied to the cook surface of a cooking utensil by arc
or plasma spraying. The pores of the coating are impregnated under vacuum
with an inert release agent of low viscosity such as food grade liquid
silicon resin. After vacuum impregnation, the impregnate is thermally
cured and the cook surface is mechanically abraded/polished to remove the
protruding peaks of metal-ceramic material to expose flattened bare metal
portions interspersed between and substantially co-planar with the
surfaces of the impregnated release agent residing in the valleys/pores.
