The invention is a method of making silicate based glass compositions with phosphorus compounds included in the composition as spectral modifiers to impart desirable color and improved energy absorbance properties. The phosphorus compound is generally a metal phosphide which is added to the batch glass composition in amounts greater than 0.05 weight percent prior to melting. The composition and method result in a finished glass suitable for use in architectural and automotive glazings.

Spectral modifiers for glass compositions

A neutral, generally green-gray low transmittance (no more than 50 percent luminous transmittance) soda-lime-silica glass has reduced solar energy transmittance and reduced ultra violet radiation transmittance when provided with the following colorant constituents in percent by weight:
