Abstract
Molten glass is conditioned to achieve a desired thermal distribution suitable for feeding the glass to a forming process. The molten glass is fed to the inlet end of a conditioning zone of a tank and glass flow through the conditioning zone is established in a direction towards a remote outlet from that zone with substantially no return flow. The glass is selectively cooled adjacent the inlet to the conditioning zone to achieve a desired temperature profile through the depth and width of a transverse cross section adjacent the conditioning zone inlet so that on flowing through that zone the further conditioning completes transformation of the glass to a state suitable for feeding to the forming process. The cooling is effected at a position selected in dependence on the temperature distribution within the glass and the required temperature profile by passing cooling fluid through at least one fluid cooled pipe immersed in the molten glass located in the forward flowing body of the glass.
