Shaping glass sheets
 Selected portions of a glass sheet are heated to elevated temperatures and offset, i.e. reformed, relative to the remaining portions of the glass sheet while maintaining the optical properties of the remaining portions of the glass sheet. The reformed area can be used as a structure to which guide brackets are other hardware can be secured or as an integral glass ledge to guide the up and down movement of the glass sheet within a vehicle door frame.
