<p>A method for producing a float glass, which comprises controlling the flow volume of a molten glass, which flows on a spout lip, by means of a tweel and continuously supplying the molten glass onto a molten metal placed in a bath to allow the molten glass to flow on the molten metal, thereby forming a glass ribbon having a predetermined thickness. In the method, an upper space in the bath was partitioned by a partitioning wall into an upstream-sided spout space and a downstream-sided main space, and a heating source arranged in a molten glass inflow space, which is a portion of the spout space and is formed by the tweel, the partitioning wall and the molten glass, can heat the molten glass.</p> |
