PROBLEM TO BE SOLVED: To provide a glass melting furnace where the possibility of the turbulence of laser reflection beams caused by bubbles on the liquid surface of molten glass in a clarifying vessel is eliminated and where the liquid surface of the molten glass can be exactly measured and observed by a laser displacement meter. SOLUTION: The glass melting furnace 10 is equipped with a melting vessel 1 to heat and melt glass raw materials, the clarifying vessel 2 to clarify the molten glass G melted in the melting vessel 1 and a working vessel 3 to flow out the molten glass G clarified in the clarifying vessel 2. In the glass melting furnace where the level of the liquid surface of the molten glass G in the clarifying vessel 2 is measured by the laser displacement meter 4 and the charging amount of the glass raw materials into the melting vessel 1 is controlled corresponding to the level change of the liquid surface, a partition part 5 to part a measuring region A with the laser displacement meter 4 is installed in the clarifying vessel 2.
