Abstract

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.
