Abstract
A precious metal bushing used for fiberizing molten glass through nozzles protruding from the lower surface of an orifice plate in the bottom of the bushing requires a substantially reduced investment in precious metal by having very short sidewalls and endwalls such that the distance from the bottom surface of a flange at the top of the bushing to the top surface of the orifice plate is more than about 0.2 inch, but less than about 0.65 inch and preferably less than about 0.5 inch.
