A method for making a polarizing glass article is provided. The method includes
first providing a precursor glass containing metal-halide particles. The precursor
glass may be encased in a gas-permeable medium. Then, form at least a first polarizing
layer and a non-polarizing region in the precursor glass. Bond the polarizing layer
to a substrate and removing the non-polarizing region to expose the polarizing
layer. Then, separate the first polarizing layer from the substrate to produce
an ultra-thin polarizing glass article measuring less than or equal to about 200
m in thickness. The method may further comprise cutting the polarizing layer
into wafers.
