Method of making colored photochromic glasses |
摘要 |
A method for modifying surface coloration in silver halide-containing photochromic glasses developed by thermal reduction treatments is described, which method comprises subjecting the glass, prior to the coloring thermal reduction treatment, to a silver ion exchange treatment during which silver ions are introduced into at least a portion of the surface of the glass article. Subsequent thermal reduction of the silver-containing surface portion of the glass provides novel colors and/or color patterns therein.
