Solar control coatings providing increased absorption or tint
A method of tinting or coloring glass. The following layers are deposited onto the glass: a first dielectric layer, a subcritical metallic layer; a primer layer; and a second dielectric layer. Alternatively, these layers may be deposited onto the glass: a first dielectric layer, a subcritical metallic layer; and a second dielectric layer. Alternatively, the invention is a coated article that includes a substrate, a first dielectric layer, an absorbing layer, and a second dielectric layer over the primer layer. The absorbing layer can be Inconel, titanium nitride, cobalt chrome (stellite), or nickel chrome material, and has a thickness in the range of 50 Å to 150 Å.
