ABSTRACT:
Method and apparatus are provided for circulating molten metal in a glass-supporting pool of molten metal in a direction counter to the advance of freshly delivered molten glass and outwardly into marginal spaces between glass restraining members and the side walls of the bath where it is subjected to forces establishing wave action in the surface of the pool of molten metal and then through means for dampening those waves to return the flow of molten metal to the main portion of the glass-supporting pool of molten metal whereby the metal can be purified and desirable thermal conditions can be established in the vicinity of the molten glass delivery onto the pool of molten metal.
