Abstract
Silicate based glass compositions with nitrogen compounds are included in the composition as performance modifiers to impart desirable color and improved energy absorbance properties. The nitrogen compound is, generally, a metal nitride which is added to the batch glass composition in amounts greater than 0.05 weight percent prior to melting the composition and method resulting in a finished glass suitable for use in architectural and automotive glazings.
