PROBLEM TO BE SOLVED: To surely control generation of bubbles in molten glass circulating in a noble metal pipe by coating the outer peripheral surface of the noble metal pipe with the molten glass simply and surely.SOLUTION: In a molten glass transfer device including a noble metal pipe 15 for circulating molten glass G through the internal space S1, and a refractory 16 for forming a filling space S2 of the molten glass G between itself and the outer peripheral surface of the noble metal pipe 15 by enclosing the outer peripheral surface of the noble metal pipe 15, the noble metal pipe 15 communicates with the filling space S2, and has a supply hole 20 for supplying the molten glass G circulating through the internal space S1 into the filling space S2. |
