Composite photochromic glass article and method of making |
摘要 |
There is disclosed a composite photochromic glass article composed of a glass core and a thin surface layer substantially encasing that core, the core preferably containing a copper-cadmium halide photochromic crystal system and the substantially encasing glass layer preferably containing a copper-cadmium-silver halide photochromic crystal system. The article may be made by fusion laminating two separately formed glasses, or by introducing silver into a surface layer on a glass article by ion exchange.
