Abstract:
In a method for melting glass which includes: providing a glass melter, a conditioner, and a forehearth; melting a glass batch in said melter to form molten glass therefrom; discharging said molten glass from said melter into said conditioner; flowing said molten glass through said conditioner to lower the temperature of the molten glass in said conditioner wherein said conditioner includes a top wall, a bottom wall and pair of side walls; and discharging said molten glass at the lower temperature attained in said conditioner into said forehearth, wherein when said molten glass flows through said conditioner the normal tendency of said glass is to create a higher temperature on the surface of the molten glass and a lower temperature beneath said surface which causes said glass to crystallize in said conditioner, the improvement comprising providing a glass flow diverting structure spaced above said bottom wall to provide a glass flow path between said bottom wall and said diverter and extending downwardly from a top wall of said conditioner into said flow path of said molten glass, extending the diverter to a depth effective to reduce the amount of crystallization in the flow path of said molten glass in said conditioner, diverting the flow of said molten glass in said conditioner with said diverter so as to divert said hotter glass from said surface of said glass flow downwardly to said effective depth thereby reducing the amount of crystallization that would have occurred without the presence of said glass flow diverting structure.
