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 for making a glass laminate sheet including: selecting a core glass composition and a clad glass composition combination for a glass laminate structure; determining and comparing the viscosity and coefficient of thermal expansion (CTE) profiles for each of the selected core and the clad glass compositions with each other over a temperature range of interest including the onset of viscoelasticity to ambient temperature; and processing the selected core and clad glass composition in a laminate fusion draw apparatus to form a laminate glass sheet in accordance with at least one difference condition for the clad effective coefficient thermal expansion (CTEeff core) and the core effective coefficient thermal expansion (CTEeff core). Another method for making a glass laminate sheet includes controlling the cooling rate to control the resulting strength of the laminate.

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.
