Abstract: A cover glass article includes a glass body having a three-dimensional shape, an inside surface, and an outside surface. Each of the inside and outside surfaces has a surface roughness (Ra) less than 1 nm and is free of indentations having diameters larger than 150 ?m.

Abstract: A glass manufacturing apparatus includes an enclosure including an interior area and a vessel positioned at least partially within the interior area of the enclosure. The vessel includes a trough and a forming wedge including a pair of downwardly inclined surfaces that converge at a root of the vessel. A draw plane extends from the root of the vessel through an opening of the enclosure in a draw direction. The apparatus includes a thermal shield moveable along an adjustment direction extending perpendicular to the draw plane. The thermal shield includes a non-metallic outer shell and a thermal insulating core. Additionally, methods of manufacturing a glass ribbon with the glass manufacturing apparatus are provided.

Abstract: Provided herein are ion-implanted glass based articles with improved flaw suppression properties. The ion-implanted glass based articles generally have a final indent fracture threshold (IFT) load of at least 650 grams, and/or a scratch threshold force of at least 10 N, which represents at least 1.25-fold enhancement compared to the glass based article prior to ion-implantation. Factors affecting the efficacy of the ion implantation process can include the IFT load of the starting glass or glass ceramic substrate (native IFT load), ion type, ion dose, implant energy, beam current, and glass temperature.

Abstract: Methods provide for post processing at least one flexible glass sheet with the step of providing the glass sheet with an initial shape. The method then further includes the step of flexing the glass sheet into a secondary shape from the initial shape. The method then further includes the step of post processing the glass sheet while biasing the glass sheet into the secondary shape. The method then still further includes the step of releasing the glass sheet to at least partially return to the initial shape.

Abstract: A glass making process comprising a step of fining the molten glass in a fining vessel comprising a top wall portion not in direct contact with the molten glass, and a side wall portion in direct contact with the molten glass, wherein the top wall portion has a temperature T(top), the side wall portion has a temperature T(side), and T(top)?T(side)?10° C., and a glass fining system. The invention is particularly useful for glass fining systems comprising a metal fining vessel made of precious metals such as Pt and/or Pt—Rh alloys.
