Crystallized glass having natural-marble-like surface patterns and method of producing the same

摘要

A crystallized glass having natural-marble-like surface patterns comprising 45 to 75 wt. % of SiO2, 1 to 25 wt. % of Al2O3, 1 to 20 wt. % of CaO, 0.5 to 17 wt. % of MgO, 0.1 to 18 wt. % of BaO, 0 to 18 wt. % of ZnO, 1 to 15 wt. % of Na2O, 0 to 7 wt. % of K2O, 0 to 5 wt. % of Li2O, 0 to 10 wt. % of B2O3, 0 to 10 wt. % of P2O5, 0 to 1 wt. % of As2O3, and 0 to 1 wt. % of Sb2O3, substantially free from nucleating agent, in which diopside type crystals are precipitated, and a method of producing the crystallized glass are disclosed.
