PROBLEM TO BE SOLVED: To provide a glass melting furnace capable of producing glass having higher quality by removing the fine bubbles included in molten glass. SOLUTION: A clarifying vessel 3 of the furnace successively provided with a raw material melting vessel 2, a clarifying vessel 3 and a homogenizing vessel 4 in the flow direction of the molten glass 7 is a hermetic structure formed of platinum or platinum alloy in the clarifying vessel 3. The inside of the vessel is formed to a rectangular parallelepiped shape and the ratio of the depth and width of the parallelepiped is 1:1.2 to 20, the ratio of the depth and the length is 1:5 to 30 and the ratio of the depth and the volume (the width×the length×the depth) is >=1:6. In addition, a gas vent pipe 15 for removing the gas in the vessel is erected in a ceiling section 14.
