  • Patent number: 10836669
    Abstract: A system and method for stirring molten material such as glass are provided. To prevent sagging of a cover of a stirring system, a portion where deformation or sagging may significantly occur is suspended by a suspension system, so that local sagging and deformation of the cover is suppressed. As a result, a crack which may occur in the cover is suppressed, and therefore, contamination of the molten material is likewise suppressed.
