METHOD FOR PRODUCING POLARIZING GLASS

摘要

Disclosed is a method for producing polarizing glass that reduces the deviance of the angle of the polarization axis in polarizing glass, and which is a simpler method than the conventional one. Said method contains a step (a) for preparing glass that contains dispersed metal halide particles, a step (b) for obtaining glass that contains dispersed and arranged shape-anisotropic metal halide particles that are transformed in a prescribed direction by applying a load onto said glass when the same is in a heated and softened state, and a step (c) for reducing said shape-anisotropic metal halide particles in the glass into shape-anisotropic metal particles, wherein the step (b) is repeated at least once, and during at least one performing of the repeated step (b), the transformation direction of said glass is the opposite direction of the direction in which said glass was transformed during the first time that the step (b) was performed.
