Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a clarification method of molten glass, especially a clarification method and a system of molten glass including a metallic clarification tank.SOLUTION: Concerning a glass production process and a glass clarification system, the glass production process includes a clarification step of molten glass 111 in a clarification tank including a top part wall part 103 not having a direct contact with the molten glass 111 and a side part wall part 105 having a direct contact with the molten glass 111. The top part wall part 103 has a temperature T (top part) and the side part wall part 105 has a temperature T (side part), and a following inequality is satisfied: T (top part)-T (side part)≤10°C. The glass production process is especially useful for the glass clarification system including the metallic glass clarification tank manufactured of a noble metal such as Pt and/or a Pt-Rh alloy.
