Claim Text:
1. A method for processing a first molten glass, comprising: having face-to-face contact between the first molten glass and an outer surface of an article comprising a noble metal, wherein the article has an inner surface that is opposite the outer surface, the inner surface extends around an interior space of the article, an entire length of the interior space has a volume and a crosswise dimension defined between opposite portions of the inner surface of the article, the crosswise dimension being smaller than the length, and wherein a wall thickness of the article is defined between the inner and outer surfaces of the article; and restricting any inward hydrogen permeation through a wall of the article, comprising having a filling material comprising a second molten glass different from the first molten glass, the second molten glass disposed in the length of the interior space so that the filling material is in face-to-face contact with the inner surface of the article and the filling material fills at least about 33% of the volume of the length of the interior space, wherein the filling material is isolated from the first molten glass by the wall of the article and the filling material is effective for restricting any inward hydrogen permeation through the wall of the article.
