Abstract: The present invention relates generally to a process for producing glass products and to an apparatus suitable for the purpose. In the process, a melting apparatus is provided with a melting tank for producing a glass melt from glass raw materials and a top furnace. Part of the surface of the melting region of the melting apparatus is covered with the glass raw materials and at least a small portion of the surface of the melting region is uncovered. In addition, energy is introduced in such a way that a vertical temperature difference can be established, such that the temperature of the glass melt at the base is greater than the temperature of the atmosphere in the top furnace.
