Effect of the Redox Potential on the Cooking and Properties of Glass

An analytical review of the literature on changes in glassmaking processes, diathermancy of molten glass and light transmission of glass as a function of the redox potential of the raw material and batch is given. Experimental data on the effect of the redox potentials (RP) of batches and cullet on the color of glasses with commercial compositions are presented. The conditions for transformations and equilibrium of iron oxides in glassmaking are examined.
