Zusammenfassung:A glass article with a length equal to or greater than about 880 mm, a width orthogonal to the length equal to or greater than about 680 mm and a thickness T defined between first and second major surfaces is described. A total thickness variation TTV across the width of the glass article equal to or less than about 4 μm. A maximum sliding interval range MSIR obtained from a predetermined interval moved in 5 mm increments across a width of the glass article is equal to or less than about 4 μm. A method of making the glass article, and an apparatus therefor are also disclosed.
