PROBLEM TO BE SOLVED: To provide a feeding device for molten glass where, even in the case heterogeneous glass flowing at the bottom area of a feeder is made to flow into a well at the bottom wall of a spout, homogenized satisfactory molten glass can be fed. SOLUTION: The feeding device for molten glass is equipped with: a cylindrical well 13 fitted to the bottom wall of the spout 2 formed at the terminal of a feeder 1 in a glass melting furnace, and having an orifice 4 exhausting molten glass G at the bottom; and a needle 5 of extruding the molten glass G in the well 13 from the orifice 4 while stirring the same by rotation and vertical reciprocation. The well 13 is projectingly provided with ribs 13b extending to the vertical direction at the inner wall. COPYRIGHT: (C)2007,JPO&INPIT
