Abstract
A flat glass sheet and a mold having a mold cavity defined by a shaping surface are provided. The shaping surface has a surface profile of a shaped glass article. At least one edge alignment pin is provided on the mold at an edge of the shaping surface. The glass sheet is leaned against the edge of the shaping surface such that an edge of the glass sheet abuts the edge alignment pin. The glass sheet is then heated. The glass sheet is sagged onto the shaping surface of the mold so that the glass assumes the surface profile of the shaped glass article and thereby form the shaped glass article. The edge alignment pin aligns the edge of the glass sheet with the mold cavity as the glass sheet sags onto the shaping of the mold. The shaped glass article is removed from the mold.
