ABSTRACT:
A centerline cooled forehearth for conditioning molten glass, wherein the sides of the flow channel of the forehearth are provided with external sheets of insulation. The channel is covered by a roof having vertical vents therethrough along the centerline with the usual burner blocks and burners spaced along the sides of the upper edge of the channel. Flue blocks are positioned immediately above the burner blocks, and their lower surfaces extend toward the centerline of the channel a greater extent than the burners, thereby serving as reflectors for the heat from the burners along the side walls of the channel.
