Abstract
This invention is concerned with the production of transparent glass articles exhibiting an integral light gray-brown hue. More particularly, this invention is drawn to specific borosilicate-based glass compositions containing critically-defined amounts of Co.sub.3 O.sub.4, NiO, and MnO.sub.2 as colorants therefor. The resulting glasses exhibit a specifically-delineated transmittance curve in the visible portion of the radiation spectrum.
