摘要

APPARATUS FOR THE MANUFACTURE OF FLAT GLASS HAVING A GLASS REFRACTORY DELIVERY PIECE An apparatus for manufacturing flat glass wherein a pool of molten metal is provided for supporting the glass during its manufacture is provided with a molten glass delivery facility that includes a refractory glass supporting member that extends into contact with the molten metal upon which the glass is to be delivered and formed, The refractory that contacts the molten metal is a gas impervious refractory, preferably a glass phase refractory, that permits the direct delivery of molten glass from the refractory support onto the molten metal while avoiding the introduction of fine seeds or bubbles into the glass.
