Abstract: An apparatus and method for manufacturing glass include a heat extractor configured to extract heat from molten glass. The heat extractor includes a first conduit and at least one second conduit which may include a plurality of second conduits circumferentially surrounding the first conduit. The first conduit and the at least one second conduit are configured to flow a fluid therethrough.

Abstract: A method of forming a glass ribbon including flowing molten glass into a sheet forming device to form formed glass. The formed glass having a first portion and a second portion, the first portion having a larger thickness than the second portion. The method further includes volumetrically heating the formed glass using an electromagnetic heating device, so that the first portion has a lower average viscosity than the second portion, and drawing the formed glass into a glass ribbon, such that the first portion is drawn with a higher rate of elongation than the second portion.

Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: A method of manufacturing a sheet of glass comprises: (a) forming a vertically oriented ribbon of glass that moves downward as a function of time, the ribbon of glass having a first primary surface and a second primary surface that face in generally opposite directions and a core disposed between the first and second primary surfaces; (b) as the ribbon of glass moves downward, passing the ribbon of glass adjacent to a first raised temperature zone liquefies the first primary surface while a temperature of the core remains below a softening temperature; and (c) after the ribbon of glass moves below the first raised temperature zone, separating a sheet of glass from the ribbon of glass. Passing the ribbon of glass adjacent the first raised temperature zone reduces total thickness variation, surface roughness, and other surface defects of the ribbon of glass.

Abstract: A method for reconditioning a glass manufacturing system includes establishing a reducing atmosphere in a glass melting vessel and draining a glass melt composition from the melting vessel while the reducing atmosphere is in the vessel. The pressure of the reducing atmosphere is greater than the pressure of the atmosphere surrounding the melting vessel and the reducing atmosphere is established by operating at least one combustion burner in the melting vessel in a fuel-rich condition.

Abstract: A method for analyzing a glass melt composition, in the manufacture of glass articles, includes sampling a gas composition comprising at least one gaseous species generated from the glass melt composition during a melting operation by taking a plurality of measurements of the gas composition over a period of time. The method also includes analyzing the sampled composition to determine an amount or concentration of the at least one gaseous species in the gas composition as a function of time.
