    Abstract: An apparatus for cold-shaping a glass sheet that includes: a plurality of vacuum chucks configured within a moveable table; a first automated pick mechanism proximate the table; an automated dispensing mechanism proximate the table; and a pressing apparatus. The first pick mechanism is configured to shape a glass sheet onto one of the chucks. The dispensing mechanism is configured to dispense a curable adhesive onto the glass sheet or a frame. One of the first pick mechanism and the dispensing mechanism is configured to position the frame onto the glass sheet such that the adhesive is disposed between the glass sheet and the frame. The pressing apparatus is configured to press the frame and the adhesive onto the glass sheet to define a finished glass sheet assembly. The glass sheet is bendable at ambient temperature. Methods for cold-shaping a glass sheet are also included in the disclosure.

    Abstract: A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.

    Abstract: A method for finishing a glass or ceramic article includes applying a force to the glass or ceramic article. The force is applied to the glass or ceramic article at least when the glass or ceramic article is at a temperature that is greater than or equal to a creep temperature of the glass or ceramic article. Holding the force to the glass or ceramic article as the glass or ceramic article is cooled to a temperature that is less than the creep temperature of the glass or ceramic article.
