INTEGRAL CAPSULE FOR BLISTER SUPPRESSION IN MOLTEN GLASS

摘要

A precious metal structure which has an internal gas permeable membrane is described herein for a glass manufacturing vessel configured to have molten glass flow therein. The internal gas permeable membrane can be supplied with an atmosphere of gas (or gases) to control the flux of hydrogen into our out of the molten glass or otherwise improve the production of the molten glass. In this manner, the undesirable detrimental reactions that can occur at the interface of the molten glass and precious metal interface which can cause defects in the molten glass such as bubbles or solid inclusions can be stopped or at least substantially reduced.

1. A glass manufacturing vessel configured to have molten glass flow therein, the glass manufacturing vessel comprising:
an external layer with a first side and a second side; an intermediate layer; and an internal layer with a first side and a second side, where the intermediate layer is positioned between the second side of the external layer and the first side of the internal layer, and where the intermediate layer has a gas permeable structure that permits an atmosphere of gas to pass therein between the second side of the external layer and the first side of the internal layer.
