Abstract
This invention is directed to the formation of transparent, surface-crystallized glass bodies exhibiting very high mechanical strengths, but low frangibility, consisting essentially, in weight percent, of 2.5-5.0% Li.sub.2 O, 5-10% MgO, 3.5-12%, ZnO, 16-28% Al.sub.2 O.sub.3, and 50-70% SiO.sub.2.
