ABSTRACT:
The thin flat glass substrate, especially for display engineering, has a thickness of less than 1.5 mm, a length of at least 1800 mm, a width of at least 1800 mm and a difference between a smallest thickness and largest thickness of less than 50 μm. The float glass process for making the improved flat glass substrate provides flags (9) in the molten metal bath in the hot-spread region on both sides of the forming glass sheet, to minimize the variation in thickness of the thin flat glass substrate formed by the process.
