Abstract
Abstract This disclosure teaches a new article of manufacture. The article includes a glass substrate and an adherent coating on the glass substrate of a gray color. The coating on the glass substrate has a composition selected from the group of glass coating compositions consisting essentially of oxides of cobalt, manganese, and copper, wherein the metal content of the metal oxide composition contains 45-60% by weight of cobalt, 26-39% by weight of manganese, and 12-20% by weight of copper. The actual weight percent of each metal is adjusted so that all metals are within their stated ranges when providing a total of 100% by weight metal. The coated glass substrate can be made into a product which has particular utility as a tinted architectural or a tinted automotive glass product.
