Abstract

Abstract Glass having ultrafine particles of CuCl and/or CuBr precipitated therein, which consists essentially of: from 10 to 70 mol % of SiO2, from 30 to 90 mol % of B2O3, from 0.1 to 50 mol % of Li2O+Na2O+K2O, and from 0.01 to 10 mol % of CuCl+CuBr. The glass may further contain from 0.01 to 40 mol % of Al2O3.
