In this paper, the theoretical and experimental model of glass refining and sand dissolution are summarized, their ideal condition are defined and the influence of most important factors on the course of both proceses is presented. In the same time, the mutual relations between examinated processes are revealed. From the comparison of attainable optimum conditions of single processes, the alternative or new arrangement, of both processes in the melting room are proposed. As is obvious from the results, the space separation of sand dissolution and refining seems to be advantageous as well as application of controlled convection in the melting part and reduced pressure in the refining part of the melting room.
