ABSTRACT:
A substrate, such as a ceramic body, carries a layer of glaze consisting essentially of (a) an inorganic oxide glass matrix that is essentially free from ions which migrate in a high-electric field, (b) about 1 .times. 10.sup.19 to 50 .times. 10.sup.19 antimony cations distributed in each cubic centimeter of the glass matrix, and (c) about 4 to 30 weight percent with respect to the weight of said glaze of discrete tin-oxide particles in the antimony-containing glass matrix. The method comprises dissolving antimony, as a compound thereof, in a glass, mixing together particles of said glass and tin-oxide particles, coating the mixture on a substrate, heating the coated substrate to melt the glass particles while retaining tin oxide in discrete particulate form, and then solidifying the molten coating.
