The present invention provides a glass-melting furnace for melting glass raw material particles to produce molten glass, which can produce molten glass having a good quality, a process for melting a glass, an apparatus for producing glass products and a process for producing glass products. Glass raw material particles are dropped from an oxygen combustion burner 24, and the glass raw material particles are heated by a flame F of an oxygen combustion burner 2 and a thermal plasma P, to melt the particles. Liquid glass particles 30 produced by the melting fall downwardly in a melting tank 12, and fall on a surface of a molten glass liquid G in the melting tank 12. Then, an upper layer G1 of the molten glass liquid G is heated by electrodes 40, 40 of a heating apparatus 38 provided in the melting tank 12. By this method, air and residual gas generated in the molten glass liquid G and the liquid glass particles 30 fallen onto the surface of the molten glass liquid G, become bubbles, surface and are smoothly discharged. |
