ABSTRACT:
Glass is melted in a furnace having a melting zone and one or more processing tanks adjacent to the melting zone. Molten glass flows from the melting zone to the processing tank through a passage. A portion of the molten glass is withdrawn from the top of the processing tank and is recirculated to the processing tank or to a separate refining zone. The furnace includes a melting section and at least one adjacent processing tank communicating with the melting section through a passage. A recirculating passage connects the top of the processing tank and the passage connecting the melting section and the processing tank. Additional means are provided to establish a recirculating flow of molten glass via the recirculating passage.
