Abstract
Disclosed are a polarizing glass comprising a glass layer(s) which contains shape-anisotropic metallic particles dispersed therein in an oriented state and a base glass which causes substantially no light scattering, said glass layer being provided on a part or whole of at least one of faces of said base glass, which has polarizing properties comparable to conventional counterparts, a largely decreased transmission loss and a strength acceptable to practical use. Processes for the production of the polarizing glass are also disclosed.
