Abstract
Silicate based glass compositions with metal silicide compounds included in the composition as performance modifiers to impart desirable color and improved energy absorbance properties. The metal silicides are 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.
