ABSTRACT:
High silica glasses exhibiting blue color by transmitted light are produced by impregnating a porous, high silica glass with a solution of cobalt, aluminum, and selected alkaline earth or alkali salts, and then consolidating the glass under oxidizing conditions to dope the glass with the corresponding oxides. The tinted glass has particular utility as a blue filter for lighting applications.
