Abstract
The invention is directed to a silver-containing polarizing boroaluminosilicate glass composition that has been doped with a noble metal selected from the group consisting of Pt, Pd, Os, Ir, Rh and Ru, including mixtures thereof, to nucleate and precipitate silver ions to silver metal without the need for a reducing atmosphere step. The invention is further directed to a method for making the glass composition of the invention. Using the composition and method of the invention, one can prepare a glass having a selected null transmission range.
