    摘要: A method for reducing surface defects during production of float glass having a transformation temperature Tg of at least 600° C. is provided. A method for removing impurities from the surface of the glass band in the floating chamber by molten metal flowing over the glass band is also provided. The undesired spreading of the molten metal on the glass band is limited in a contactless manner. A device is also provided for carrying out the method, in addition to a floating glass having a transformation temperature of at least 600° C., which has a maximum of 3 surface defects (top specks) having a size greater than 35 μm per m2 when it leaves the floating chamber.
