ABSTRACT:
Glass is melted in a furnace having a melting zone and one or more processing zones adjacent to the melting zone. A volume of molten glass is caused to flow from the melting zone to the processing zone in a volume which exceeds the volume of glass withdrawn from the processing zone. The excess volume of glass is returned to the melting zone 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 is provided between the processing tank and the melting section and additional means are provided to establish a circulating flow of molten glass via the recirculating passage.
