Abstract
PURPOSE:To obtain the titled product having sufficient properties for building and decoration, by molding glass having a specific composition containing no nucleating agent and heat-treating the molded article to give main crystal consisting of forsterite and gahnite. CONSTITUTION:Glass having the following composition is molded into a given shape, the molded article is heat-treated and crystallized to give a glass product comprising forsterite as one main crystal and either gahnite or crystal of augite as main crystal. The glass applied has 45-63wt.% SiO2, 5-22wt.% Al2O3, 8-30wt.% MgO, 1-14wt.% ZnO, 1-9wt.% N2O, 1-6wt.% K2 (with the proviso that 2-12wt.% Na2O+K2O), 0-12wt.% CaO, 0-5wt.% BaO and 0-5.5wt.% B2O3, contains no nucleating agent such as TiO2 and has >=90wt.% based on total amounts of sum of the whole components.
