Effect of glass batch redox potential on glass melting and properties

An analytical review of the literature on the change in the processes of glass melting, the thermal transparency of the molten glass, the light transmission of glass, depending on the redox potential of the raw material and the charge, is given. Experimental data on the effect of oxidation-reduction potentials (ORP) of charges and glass breakage on the color of industrial glasses are presented. The conditions of transformation and equilibrium of iron oxides during glass melting are considered.
