Abstract:
1. A curved glass pane, comprising float glass, which is curved in a transverse float direction and a longitudinal float direction, the transverse and longitudinal float directions being mutually orthogonal, wherein: the curved glass plane has a main face area greater than 1.5 m a product of a largest depth of transverse bending and a largest depth of longitudinal bending of the curved glass pane is greater than 3000 mm a point located on the normal to a surface passing through the center of gravity of the glass pane has a radius of curvature of less than 3 m in any direction; and a variation in the thickness of the glass pane in the longitudinal float direction is less than 10 μm over 500 mm.
