The main difficulties of making an accurate determination of the redox state of glass are noted. The specific effect of tin on the valence equilibrium of iron in the surface layers of float-glass is shown. The spectrophotometric method of determining heterovalent forms of iron in commercial silicate glasses, which is applicable for flat and hollow articles, is described. The method is distinguished by high speed and accessibility.
