The model of calculation of the simultaneous oxidation-reduction equilibria in non-isothermal flowing glass melt has been formulated. The behaviour of bubbles in a model glass melting furnace has been examined using this model. The calculations involved soda-lime-silica glass containing sulphate ions and ions of iron as well as glass for the production of TV panels with antimony and cerium. The results of calculations confirmed results acquired under isothermal conditions. The internal partial pressure of the refining gas, the bubble growth rate and the refining rate grew with the increasing initial redox state of glass in the glass for TV panels. In the glass containing sulphate ions, the driving force of refining (the sum of the internal partial pressures of SO2 and O2 in the melt) exhibited minimum at medium values of initial redox state of glass.
