Na 2 O 3SiO 2 glasses with high water content were prepared under high‐pressure, hydrothermal conditions and their chemical durabilities in water were measured at atmospheric pressure and 30°C. Chemical durability decreases with increasing water content, which is probably due to a positive dependence of H + (or H 3 O + ) diffusivity on water content.
