An approach is developed for understanding formation of gel films on glass surfaces during water exposure. Compositional and microstructural data from ir reflection spectroscopy, scanning electron microscopy, and electron microprobe analysis are used with parameters defined from solution‐analysis data to produce an SiO 2 composition profile of the corroded surface. This model profile is compared with a measured profile and used to interpret differences in corrosion resistance of binary Li 2 O‐ and Na 2 O‐SiO 2 glasses. Effects of corrosion temperature on surface gel structure are also discussed.
