Beschreibung
Zusammenfassung:	A method of reducing accelerated metal loss from the inner refractory metal of a component of a glass making system. The method utilizes a sacrificial metal member which saturates free volume regions surrounding the component with an oxide vapor of the sacrificial metal member. L'invention concerne un procédé destiné à réduire la perte de métal accélérée, provenant d'un métal réfractaire interne d'un composant d'un système de fabrication du verre. Le procédé utilise un élément métallique sacrificiel qui sature en vapeur d'oxyde dudit élément métallique sacrificiel, les zones de volume libre entourant le composant.
