    摘要： There are disclosed an improved method for production of a polarizing glass having a high extinction ratio by facilitating control of the diameter of silver halide particles in a mother glass with high Ag concentration, and a polarizing glass produced by the method. The glass is a polarizing glass having dispersed and oriented geometrically anisotropic metallic silver particles at least in its surface layer, which is characterized by not containing TiO2 exceeding 1.7 wt % but containing not less than 0.4 wt % Ag, and in that Ag and halogens contained therein satisfy the following relations: the molar ratio of Ag/(Cl+Br) is 0.2 to 1.0; the molar ratio of Cl/(Cl+Br+F) 0.5 to 0.95; and the molar ratio of Br/(Cl+Br+F) 0.05 to 0.4. The method for production comprises the steps of drawing a glass containing dispersed AgClxBr1-x crystals, and then reducing it under a reducing atmosphere.
