The present invention relates to a molten glass stirrer which can stir glass. More particularly, the molten glass stirrer comprises: a mixing tank to which molten glass is accommodated; an upper cover joined to an opening of the mixing tank, having a cover hole; a mixing unit of which one side is immersed in molten glass while penetrating through the cover hole, and the other side is extended to outside of the mixing tank; and a heating unit which includes a housing partitioning a heating space surrounding at least part of the other end of a shaft, and a heater heating the heating space. According to the present invention, the molten glass stirrer forms a heating space which is heated by a heater and is between the cover hole through which the shaft penetrates and a space outside the mixing tank; and elevates the temperature of the cover hole, thereby preventing volatile gas generated inside the mixing tank from condensing to the heating space and the cover hole, or to the shaft penetrating through the heating space and the cover hole. |
