The simple model presented takes into account the possible accumulation of a refining agent under the glass batch in the melting rooms with vertical flow. The relations describing an increase of the refining agent concentration in the glass melt have been derived from the mass balance of the refining agent and the calculations have been performed showing the influence of the main factors on the process. The necessery experimental data have been collected and the effect of the refining agent accumulation on the refining behaviour has been demonstrated.
