Abstract
Methods for reforming a glass-based sheet by gravity sagging comprising placing a glass-based sheet over a mold, placing a glass-based patch on a top surface of the glass-based sheet, and heating the glass-based sheet and the glass-based patch to a reforming temperature such that both the glass-based sheet and the glass-based patch deform into the mold cavity under gravitational force. The glass-based patch can be sized and positioned on the top surface of the glass-based sheet to prevent the formation of a wrinkle during the reforming method. The glass-based sheet can be reformed using an apparatus comprising the mold and one or more of the glass-based patches fixed relative to a top surface of the mold.
