ABSTRACT:
This invention is directed to the production of a silver halide-containing glass article essentially free from silver halide crystals exhibiting a bright yellow coloration which strongly attenuates the transmission of ultraviolet radiation and radiation having a wavelength up to about 450 nm, said article having an integral reduced surface layer thereon, the depth of that layer being sufficient to effectively prevent the transmission therethrough of ultraviolet radiation and radiation having a wavelength up to about 450 nm.
