Infrared spectra of two soda‐lime silicate glasses were measured after different times of hydration and dehydration. The height of OH and molecular water bands increased proportionally to the square root of time during hydration. The amount of dehydration with time was fit with a diffusion model; the diffusing species was probably molecular water. The rate of dehydration of the two laboratory glasses was many orders of magnitude faster than the rate for a commercial soda‐lime glass, consistent with the presence of a transformed layer on the surface of the hydrated laboratory glasses.
