1. A method of transferring molten aluminum from a melting furnace to a casting furnace, the steps comprising:
- (a) providing a transfer furnace having a plurality of chambers with at least one connection between the chambers, the connection being structured to provide for the transfer of molten metal between the chambers while allowing the melt level in one of said chambers to be higher than in another of said chambers;
(b) supplying molten aluminum to the transfer furnace; and
(c) overflowing the transfer furnace such that the molten aluminum flows through a trough and downspout into a casting furnace.
