Summary: | A glass glass-ceramic composite comprises a substrate comprising an alkali-containing glass bulk, the bulk comprising Al2O3 and SiO2 and alkali, and a glass-ceramic surface layer, the surface layer comprising an alkali-depleted glass ceramic comprising Al2O3 and SiO2 with at least 5% crystalline phase by volume, wherein the alkali-depleted glass ceramic surface layer comprises a mol % Al2O3 of at least 51%. A method of preparing the composite is also disclosed. |
