Na 2 O‐SiO 2 glasses with high water contents (up to =72 wt%) were prepared under high‐pressure hydrothermal conditions. Hardness, crack initiation, and glass‐transition temperature were investigated. The hardness and the glass‐transition temperature decreased and the crack initiation threshold increased with increasing water content, which suggests that dissolved water promotes deformation by plastic flow.
