ABSTRACT:
This invention is directed to the production of spontaneous essentially non-crystalline opal glasses exhibiting a very dense, milky-white appearance and excellent resistance to weathering and attack by alkaline detergents consisting essentially, expressed in weight percent on the on the basis, of 1.9-3.6% K.sub.2 O, 4.2-7.3% Na.sub.2 O, 0.2-3% Li.sub.2 O, 0-1.2% MgO, 0-4.9% CaO, 0-12.5% BaO, 0-0.1% NiO, 0.4-4% ZnO, 5.3-9.6% B.sub.2 O.sub.3, 8.8-13.5% Al.sub.2 O.sub.3, 57.2-64.4% SiO.sub.2, and 1.0-2.2% F., where the sum of (MgO+CaO+BaO) is preferably in the range of 4.5-12.5%.
