METHOD FOR PRODUCING GLASS AND STIRRING DEVICE

摘要

This method for producing glass is provided with a stirring step for stirring molten glass (MG). The stirring step comprises a first stirring step and a second stirring step. In the first stirring step, molten glass (MG) is stirred in a first stirring tank (100a) while guiding from bottom to top. In the second stirring step, the molten glass (MG) stirred in the first stirring step is stirred in a second stirring tank (100b) while guiding from top to bottom. The first stirring tank (100a) is provided with a first discharge tube (110a) that can discharge the molten glass (MG) from the bottom of a first chamber (101a). The second stirring tank (100b) is provided with a second discharge tube (110b) that can discharge the molten glass (MG) from the liquid level (LL) of the molten glass (MG) in a second chamber (101b).
