Abstract: Complexly-curved glass articles and methods of forming the same are described herein. The glass articles described herein may be reformed via application of vacuum pressure thereto. The glass articles may comprise a first glass layer comprising a first non-developable curved shape defined by a first curved surface and a second curved surface. At least one of the first curved surface and the second curved surface comprises a surface area of 60.000 mm2 or more. A thickness of the glass articles may comprise a uniformity of +/−75 microns per 1000 mm2 of surface area. The non-developable curved shape may comprise a maximum compressive strain shape parameter, as measured between an imaginary central surface disposed between the first curved surface and the second curved surface and an imaginary surface, of greater than or equal to 3.0%.
