Abstract

Article en verre photochromique qui comprend une pièce en un verre de silicates dont au moins une portion contient une phase photochromique séparée comportant des gouttelettes de phase secondaire à taille de 300 à 1000 Angström contenant des particules de phase tertiaire ayant une taille de 20 à 50 Angström, ladite phase séparée contenant du cuivre, du cadmium, de l'argent, et au moins un halogène choisi dans le groupe formé par le chlore, le brome et l'iode. Le verre de silicates présente une composition comprenant, en proportions pondérales calculées à partir de la charge, au moins environ 0,01 % d'Ag, 0,03 % de CuO, 0,4 % de CdO, et 0,03 % au total d'halogènes choisis dans le groupe formé par le chlore, le brome et l'iode, et il présente une inflexion d'absorption à 370 ni ainsi que des propriétés conjointes de décoloration optique et d'assombrissement superficiel. Application à l'optique, notamment
