Abstract
It is demonstrated that transformations of iron oxides in glass melting occur mainly in the solid phase. The ratio between the two forms of iron oxides in a glass melt is determined by the melt temperature. Achieving an equilibrium with the gaseous medium requires a long time due to high melt viscosity and low diffusion coefficients. To ensure high service parameters in products, one needs stability of raw material compositions and melting process parameters, including diathermancy of the melt.
