The method of manufacturing a molten glass, a glass melting furnace, a glass product manufacturing apparatus, and a method of manufacturing a glass product

The present invention, glass melting furnaces to implement the glass raw material particles and glass cullet pieces by air during the melting process method of producing molten glass producing molten glass, the manufacturing method, manufacturing apparatus for a glass product having the melting furnace, and a process for producing glass products using the above manufacturing method. A glass raw material particles introduced portion disposed downwardly on the ceiling wall 18 of the melting tank 12, an oxygen combustion burner 26 which heats the glass raw material particles 32 in the drop forms a flame 30, liquid glass particles, the ceiling wall 18 at least the surface that is placed downward, and glass cullet pieces turned tube 36 for the short diameter (a) turns on the glass cullet pieces 42 is 0.5 mm
