Abstract
Chemically durable non-silicate glasses derived from compounds including phosphates, borates, arsenates, sulfates, tellurates, tellurites, germanates and the like, are prepared by forming a melt from monobasic compounds of stoichiometric proportions, said melt then being polymerized by suitable means in the melt stage and subsequently cooled to form a desired glass. The resulting glass exhibits properties not normally found in similar glasses prepared from melts of oxides of the same materials.
