By dissolving the alkali in the glass composition, a porous surface is left that consists of the silica network with holes where the alkali has been removed by the acid. Corrosion by water is similar to acid corrosion in that alkali is removed from the glass surface. Water<span> corrosion acts at a much slower rate.
