PROBLEM TO BE SOLVED: To provide a molten glass supply apparatus which is free from the quality or yield deterioration of a glass molded product caused by generation of two heterogeneous phases or chipping-off of agitation blades even when requested to substantially increase the flow of molten glass by effectively improving a supply passage exclusive for highly viscous materials. SOLUTION: The molten glass supply apparatus 1 is provided with a fusion kiln 2 being a supply source of the molten glass, and the supply passage 4 for supplying the molten glass flowing out of the kiln 2 to a molding device 3. The molten glass has a characteristic such that its temperature corresponding to the viscosity of 1,000 P is≥1,350°C. Further, on the way of the supply passage 4, multiple agitation vessels K1, K2 for homogenization are disposed adjacently to each other in the upstream and downstream directions.
