摘要： The present invention is a method for reducing warpage of a glass sheet produced by a float process. This warpage occurs due to chemical strengthening treatment of the glass sheet. In the method of the present invention, a glass sheet produced by a float process is maintained in a temperature range from a temperature 70° C. lower than a strain point of the glass to a temperature 20° C. higher than the strain point for at least 10 minutes before the glass sheet is subjected to chemical strengthening treatment.

摘要： The glass sheet of the present invention is a glass sheet with a thickness of 1.6 mm or less produced by a float process in which a molten glass material is formed into a sheet on a molten metal. When one surface of the glass sheet kept in contact with the molten metal during the formation of the molten glass material into the glass sheet is defined as a first surface and the other surface of the glass sheet opposite to the first surface is defined as a second surface, at least the first surface has a protective coating formed thereon by dealkalization, and the second surface has an etching rate of 2 nm/min or less when the second surface is etched using 0.1 mass % hydrofluoric acid at 50° C. as an etching liquid.

摘要： A method of the present invention for producing glass sheets includes the steps of: (I) forming a molten glass raw material into a glass ribbon on a molten metal; and (II) bringing an acid gas that contains a fluorine element (F)-containing acid and in which a volume ratio of water vapor to the acid (a volume of the water vapor/a volume of the acid) is 0 or more and 30 or less, into contact with a surface of the glass ribbon on the molten metal so as to subject the surface of the glass ribbon to dealkalization and control a morphology of the surface in accordance with the volume ratio.
