Abstract

Manufacturing procedure of a phototropic glass, characterized by the fact that this glass has as its main component P2O5, glass-forming, which is mixed with other mixing components, the whole set is melted in commercial commerce, poured, molded and it is tempered between one and three hours at five hundred and sixty degrees Celsius up to six hundred and forty degrees Celsius, achieving certain precipitations of non-crystalline phases, rich in silver and halogens, which determine its phototropic properties.
