Abstract
A family of aluminoborate glasses that are compatible with aluminum at elevated temperatures, and an article comprising such a glass with either an aluminum coating, or with aluminum particles dispersed within the glass, whereby the glass may be rendered polarizing. The base glass consists essentially of, 15-85% B.sub.2 O.sub.3, 5-45% Al.sub.2 O.sub.3 and 10-75% Li.sub.2 O+RO, where RO represents the alkaline earth metal oxides MgO, CaO, SrO and BaO, and is free of oxides reacting with aluminum at elevated temperatures.
