    摘要: The present invention relates to a method for producing a float glass sheet, containing a step of melting a glass source material, a step of forming the glass melted in the previous step into a glass ribbon while allowing it to float on a molten metal, and a step of annealing the glass ribbon, in which the float glass sheet is a soda lime silicate glass, and in the forming step, a top surface of the glass ribbon that is opposite to a bottom surface thereof to be in contact with the molten metal is subjected to a dealkalization treatment in the float bath for 1 to 30 seconds and a surface temperature of the glass ribbon during the dealkalization treatment is 600° C. or higher.
