摘要： An optically activated bleaching process effective to permanently modify the color of surface-colored silver halide-containing photochromic glasses produced by thermal reduction treatments is described, wherein the glass is coincidentally exposed, for an effective time interval, to (i) a source of high energy light and (ii) a heat source. The process reduces the relatively strong absorption peaks characteristic of the initially colored glass, resulting in a permanent bleached appearance.

摘要： The instant invention is concerned with a method for producing shades of a tint in a photochromic glass, the hue of which will be essentially permanent even after subjecting the glass to temperatures up to about the strain point of the glass. Silver halide crystals constitute the photochromic agents, the glass contains lead, and the method contemplates exposing such a glass to a gaseous reducing atmosphere at temperatures above the strain point of the glass to cause the reduction of silver ions to metallic silver and the reduction of lead ions to metallic lead which coats or alloys with the metallic silver.
