  • Removal Of Bubbles From Molten Glass
    Publication number: 20200290913
    Abstract: A method for removing bubbles from molten glass is provided and involves subjecting the surface of the molten glass to at least one fining sequence wherein the fining sequence comprises subjecting the surface of the molten glass to a sub-atmospheric pressure (relative vacuum less one atmosphere of pressure) for a time followed by subjecting the surface of the molten glass to super-atmospheric gas pressure (greater than one atmosphere of pressure) for additional time. The fining sequence can be repeated as needed to produce a high quality optically clear glass that is substantially free of bubbles.
