Abstract
The specification discloses a method for making a curved, conductively coated glass member, and the resulting product, by providing for a sufficient degree of substoichiometry at the moment of bend that the glass can be bent using conventional bending techniques without crazing the coating. Two alternative methods for achieving the degree of substoichiometry are disclosed. One involves coating the part to an initial light transmittance (T.sub.o) which is lower than that typically sought by prior artisans. The other involves bending the part in a reducing environment. Also disclosed is a method for increasing conductivity of the coating by exposing the coated part to a reducing environment at temperatures considerably higher than those heretofore thought feasible for use in reduction curing.
