ABSTRACT This specification is directed to a new article of manufacture. In particular, the article is a glass sheet having first and second sides spaced apart in generally parallel planes with a multilayer coating on one of the sides of the glass sheet. The side of the glass sheet having the multilayer coating thereon is designated as the film side of the glass sheet while the other side is designated as the glass side of the glass sheet. The multilayer coating film is a film selected from the group of films consisting of a copper, stainless steel, titanium dioxide multilayer film; a copper, titanium, titanium dioxide multilayer film; and a copper, titanium, titanium nitride multilayer film. The multilayer coating film is characterized, when applied to 6 mm thick clear glass, as having: (1) a film side Y-x-y chromaticity value of reflective color falling within area A of the graph of Fig. 1 of this specification; (2) a glass side Y-x-y chromaticity value of reflective color falling within area B of the graph of Fig. 2 of this specification; (3) a visible transmittance of 5-40% for an illuminant "C" light source; and (4) a capital Y reflectance value from 5-55 for film side reflectance and 10-45 for glass side reflectance. The color generated by this glass is one which gives a very soft copper color of great beauty and very desirable for glazing used for large building structures.
