Abstract
A cooling bushing flange having a reduced amount of precious metal is provided for a glass fiber production apparatus. The flange includes a first portion formed of a precious metal or a precious metal alloy extending outwardly from a bushing and a second portion formed of a non-precious metal. The non-precious metal portion of the flange may be affixed to the precious metal portion by known metal bonding methods. A cooling tube is positioned on the non-precious metal portion to create a thermal seal and prevent molten glass from leaking from the interface of the bushing block and bushing. The precious metal portion of the inventive flange is a fraction of the size of precious metal present in conventional bushing flanges. By reducing the amount of precious metal incorporated in the flange, a significant reduction in the overall cost of the bushing and in the manufacture of glass fibers can be obtained.
