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: Methods for producing glass articles from laminated glass tubing include introducing the glass tubing to a converter. The glass tubing includes a core layer under tensile stress, an outer clad layer under, and an inner clad layer. The methods include forming a feature the glass article at a working end of the laminated glass tubing and separating a glass article from the working end of the laminated glass tubing, which may expose the core layer under tensile stress at the working end of the glass tubing. The method further comprises remediating the exposed portion of the core layer by completely enclosing the core layer in a clad layer. Systems for re-cladding the exposed portion of the core layer as well as glass articles made using the systems and methods are also disclosed.

Abstract: Disclosed is a laminated glass structure with one or more inner glass layers with at least one in tension and two outer glass layers in compression wherein one or both of the outer layers at least partially wrap around the one or more inner layers at one or more of the edges of the laminated glass structure. Also disclosed is a process for forming a laminated glass structure, comprising providing a laminated glass structure, removing at least some glass from at least one the edges of the structure to produce a concavity in at the at least one edge and applying heat to the at least one edge.

Abstract: A method for severing a glass sheet includes preferentially heating a region of the glass sheet to form a softened region. A slit is formed in the softened region of the glass sheet to form a slit region. The slit extends at least partially into a thickness of the glass sheet. Heat is preferentially applied to the slit region of the glass sheet.
