Abstract
Embodiments disclosed herein include systems and methods for controlling material warp that include placing the shaped mold in a heating device, forming a glass material into a shaped mold, and cooling the glass material and the shaped mold to a predetermined viscosity of the glass material. Some embodiments include, a predetermined time prior to removing the glass material and the shaped mold from the heating device, holding the glass at the mold in the heating device where the heating device temperature is substantially equal to mold and glass temperature just prior to exiting to ambient temperature. Some embodiments include removing the glass material and the shaped mold from the heating device to further cool the glass material and the shaped mold at ambient temperature, where after removing the glass material and the shaped mold from the heating device, the glass material will exhibit controlled or desired material warp.
