Abstract
A method of manufacturing glass comprises a stirring step in which molten glass MG is stirred. The stirring step comprises a first stirring step and a second stirring step. In the first stirring step, the molten glass MG is stirred while being directed upward from below in a first stirred tank 100a. In the second stirring step, the molten glass MG stirred in the first stirring step is stirred while being directed downward from above in a second stirred tank 100b. The first stirred tank 100a has a first discharge pipe 110a capable of discharging the molten glass MG from the bottom of a first chamber 101a. The second stirred tank 100b has a second discharge pipe 110b capable of discharging the molten glass MG from the liquid level LL of the molten glass MG in a second chamber 101b.
