ABSTRACT:
A composite body consisting of a glass or glass-ceramic substrate with a non-stick, heat resistant resin composition bonded to a surface thereof. Suitable substrates are those which contain one or more differentially etchable components. Particularly useful are glass compositions which undergo phase separation upon heat treatment. For example, some borosilicate glasses separate into a silica-rich phase and a borate-rich phase when heated to about 600.degree. C. and maintained at that temperature for about one hour. The substrate is etched to remove at least a portion of one component to provide a bonding surface containing extremely small pores of relatively uniform diameter for a non-stick heat resistant resin composition. The resin composition is uniformly applied to the etched substrate in liquid form and subsequently hardened, suitably by fusion, to form a solid, substantially continuous film over the etched surface.
