Title
(EN) METHOD OF CONTROLLING BUBBLES IN A GLASS MAKING PROCESS
(FR) PROCÉDÉ DE RÉDUCTION DES BULLES DANS UN PROCÉDÉ DE FABRICATION DU VERRE
Abstract
(EN)
Methods are disclosed for shrinking bubbles on the free surface of a volume of molten glass contained within or flowing through a vessel, thereby minimizing re-entrainment of the bubbles into the volume of molten glass and reducing the occurrence of bubbles in finished glass products produced from the molten glass. Methods of identifying a source location for the bubbles is also described.
(FR)
L'invention concerne un procédé de réduction des bulles sur la surface libre d'un volume de verre fondu contenu à l'intérieur d’un récipient ou s'écoulant à travers celui-ci, ce qui réduit au minimum le ré-entraînement des bulles dans le volume de verre fondu et diminue l'apparition de bulles dans des produits de verre finis produits au moyen du verre fondu. L'invention concerne également des procédés d'identification d'un emplacement source pour les bulles.
