ABSTRACT:
A method and apparatus are provided for inhibiting the generation, nucleation and growth of gas bubbles at a refractory surface in the vicinity of molten metal by providing a glaze of glass on the refractory surface, which glaze becomes viscous at the temperature reached in the apparatus during initiation of molten glass delivery such that some of the glaze is permitted to slough off from the refractory during initiation of molten glass delivery.
