    Abstract: Compositions comprising sodium oxide and optionally other alkali metal oxides, a glass network-forming oxide such as SiO2 or GeO2, a modifying oxide such as Al2O3 or Ga2O3, a halogen such as Cl or F, and an electron donor constituent such as sulfur, selenium or tellurium, are melted to form glasses which may be reversibly photochromic, and are thermally crystallized to form glassceramics comprising sodalite or analogous crystal phases which are also reversibly photochromic. The glasses and glass-ceramics may also exhibit induced fluorescence in the activated (darkened) state.

    Abstract: This invention relates to the production of glasses in the alkali metal aluminoborosilicate composition field containing reduced iron and chloride which are colorless, transparent, and strongly absorbing of radiation wave lengths longer than 0.7 microns. More particularly, this invention relates to glasses consisting essentially, by weight on the oxide basis, of about 312% R2O, 3-10% A12O3, 18-30% B2O3, 45-65% SiO2, 0.3-1% FeO, and 0.5-5% Cl, wherein R2O consists of 0-5% Li20, 2-12% Na20, and 010% K20.
