Apparatus and methods for processing molten material

A method of processing molten glass-forming material comprising:

• flowing the molten glass-forming material through an interior of a conduit along a travel path defined by the conduit from a first station to a second station of a glass manufacturing apparatus;
• feeding a coding fluid through at least two inlet ports into a pressure chamber extending along a cooling axis extending transverse to the travel path between a first lateral side and a second lateral side of the conduit;
• forcing the cooling fluid from the pressure chamber through a port as a sheet of cooling fluid formed at the port, wherein the port is elongated along the cooling axis;
• and
• cooling the molten glass-forming material within the interior of the conduit by forcing the sheet of coding fluid from the elongated port against an exterior of the conduit.
