Abstract:
Glass-based articles that include a hydrogen-containing layer extending from the surface of the article to a depth of layer. The hydrogen-containing layer includes a hydrogen concentration that decreases from a maximum hydrogen concentration to the depth of layer. The glass-based articles exhibit a high Vickers indentation cracking threshold. Glass compositions that are selected to promote the formation of the hydrogen-containing layer and methods of forming the glass-based article are also provided.
