FEP 4.2.10 Precipitation of silicates/silica gel and glass dissolution

Since glass dissolution rates depend on Si concentration in solution (see 2.1/2.06) the precipitation of silicates may influence the rates if silicate precipitation rates are similar (not much smaller) to the dissolution rates. There is experimental evidence that these rates may be comparable in the long term. This process is included implicitly in the glass corrosion rates, see also 2.1/2.06.
