The rate of bulk crystallization and shear viscosity η of a zinc borosilicate simulated nuclear waste disposal glass (SNWDG) were measured above the glass transition temperature T g . Using recent theories and experimental data for the temperature dependence of η at < T g , the crystallization rate below T g was calculated; well below T g the SNWDG (and, more generally, any high‐silica glass) will not crystallize appreciably over any important time period for radioactive decay of fission products.
