Abstract
An article of manufacture, such as cookware, having a composite layer adhered thereto and a process for forming it are disclosed, characterized in that the layer is a porous ceramic body having a continuous, communicating pore structure, and a film-forming, polymerized organic resinous impregnant, such as a silicone compound, fills at least some of the pores. The impregnant is adapted to serve as a release agent. As a result, the article acquires a composite layer having at least the abrasion resistance of the ceramic and the release properties of the resinous impregnant.
