X-RAY INDUCED COLORATION IN GLASS OR GLASS-CERAMIC ARTICLES

摘要

Embodiments of the present disclosure are directed to methods for inducing color change in glass and glass-ceramic articles. According to one embodiment, color change may be x-ray induced in glass or glass-ceramic articles. The method for x-ray inducing color change may include exposing the glass or glass-ceramic article to x-rays at a temperature of up to 200° C to induce a colored area in the glass or glass-ceramic article. The glass or glass-ceramic article may comprise: 50-85 mole% SiO2;5-25 mole% Al2O3; 0-15 mole% P2O5; 0-15 mole% B2O3; 5-25 mole% R2O, wherein R2O = Li2O + Na2O + K2O.
