ABSTRACT:
A powdered raw material feeding device is mounted beside a glass melting tank for feeding the powdered raw materials of glass onto a surface of molten glass in the tank. The raw materials thus riding on the molten glass are forced to move in the downstream direction in response to the feeding of the raw materials to the tank. An obstruction device is stationarily mounted in the way of a heap of the raw materials on the molten glass so that an extreme end of the obstruction device is embedded in the heap of the raw materials on the molten glass at a position near the laterally central position of the path of the heap, whereby upon movement of the heap in the downstream direction, a certain magnitude of flow resistance is applied to the heap of the raw materials.
