The glass composition forms predominantly bismuth titanate and/or zinc titanate crystals upon firing. Preferably, glass compositions include by weight from about 11% to about 52% SiO2, from 3.4% to about 40% TiO2, up to about 75% Bi2O3, up to about 40% by weight ZnO, where the sum of Bi2O3 and ZnO comprises from about 15% to about 85% of the ...
