Abstract
A method is disclosed for preparing for operation a cell, having an outer shell and an inner lining, which is employed to produce metal by electrolysis of a compound of the metal in a molten production bath. The method includes placing in the cell an initial bath having a solidus temperature higher than the solidus temperature of the production bath, and higher than the temperature maintained on the inside surface of the shell. Because of this higher solidus temperature, a freeze-line barrier for the initial bath is established within the lining of the cell. Subsequently, electrolysis is carried out in the production bath.
