ABSTRACT:
A vertical standpipe which has an internal fitting. The standpipe conveys a molten glass stream from a molten bath in a furnace forehearth to a spinner below the forehearth. The internal fitting has an orifice positioned so as to maintain a spaced-apart relationship between the interior surface of the standpipe and the molten glass stream issuing from the orifice. The mass flow rate of the molten glass stream is throttled by variable cooling means in the vicinity of the orifice.
