ABSTRACT:
An article includes a substrate, e.g. a glass sheet having a first major surface and an opposite second major surface having a textured surface to provide a predetermined pattern on the second surface of the substrate, and an overlay, e.g. a coating over the pattern. The percent of visible light transmittance, and percent visible light reflectance, of the substrate and the overlay is selected such that the pattern is visible when the article is viewed through one of the surfaces of the substrate or overlay. In one non-limiting embodiment, the substrate is glass and the article has a metallic appearance. In another non-limiting embodiment, the overlay is a transparent coating deposited on the second surface of the glass sheet into grooves of the pattern. Other non-limiting embodiments include the substrate having a Delta % haze of greater than 15%, and a protective overcoat over the coating.
