Abstract

A sag-bending glass mold for creating a partial parabolic-curved glass sheet is disclosed. The glass mold comprises a glass-support surface having a cross-sectional profile of varying height. The cross-sectional profile has a first portion with profile of a non-parabolic, linear-square root composite shape. A method for forming a partial parabolic glass sheet is also disclosed. The method comprises positioning a planar glass sheet on a sag-bending mold having a linear-square root composite shape and deforming the glass sheet to follow the linear-square root composite shape of the sag-bending mold.
