    Abstract: A method for producing a glass substrate includes (a) a step of forming molten glass having a temperature T2 less than or equal to 1500° C. on molten tin having an iron concentration greater than or equal to 100 ppm to produce a glass ribbon having a temperature T4 less than or equal to 1100° C. and a logarithm log ρ greater than or equal to 8.8, and (b) a step of cooling the glass ribbon to room temperature to produce the glass substrate. The temperature T2 represents a temperature when a logarithm of a viscosity η (dPa·s) is 2, the temperature T4 represents a temperature when the logarithm of the viscosity η (dPa·s) is 4, and the logarithm log ρ represents a logarithm of a volume resistivity ρ (Ω·cm) at 150° C.

    Abstract: The present invention relates to a float glass for chemical strengthening, containing a bottom surface coming into contact with a molten metal at the time of forming and a top surface opposing the bottom surface, in which a difference Δ(N—Na2O2) determined by subtracting a square of a normalized Na2O surface concentration of the bottom surface which is a value obtained by dividing an Na2O concentration in the bottom surface by an Na2O concentration at a depth position of 100 μM therefrom, from a square of a normalized Na2O surface concentration of the top surface which is a value obtained by dividing an Na2O concentration in the top surface by an Na2O concentration at a depth position of 100 μm therefrom, is 0.040 or less.
