The present invention provides a glass-melting furnace etc which can maintain homogeneity of molten glass in an apparatus and a process for producing molten glass by melting glass raw material particles and glass cullet pieces. In the present invention, glass raw material particles are dropped from a glass raw material particle heating unit 14 constituted by oxygen combustion burners 34, 34··· and a glass raw material particle feed portion, and the glass raw material particles are changed into liquid glass particles 38, 38··· in high-temperature gas phases produced by flames 32, 32··· of oxygen combustion burners 34, 34···. In the step of heating and melting the glass raw material particles, glass cullet pieces 30, 30··· are feed by an feed means 40 of a glass cullet piece feed portion 12 so as to be spread radially toward the plurality of flames 32, 32··· around the feed portion. |
