Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a glass clarification system capable of providing a high clarification temperature to molten glass without exceeding the maximum metal operation temperature.SOLUTION: A glass manufacturing process includes the step of clarifying molten glass 111 in a clarification tank having a top part wall portion 103 without directly contacting the molten glass and a side part wall portion 105 directly contacting the molten glass. The glass clarification system including a metal glass clarification tank made of noble metal, such as Pt and/or Pt-Rh alloy has the top part wall portion 103 having a temperature T (the top part) and the side part wall portion 105 having a temperature T (the side part). T(the top part)-T(the side part)≤10°C.SELECTED DRAWING: Figure 1 【課題】金属の最高動作温度を超えることなしに、溶融ガラスに高い清澄化温度を提供するガラス清澄化システムの提供。【解決手段】ガラス製造プロセスは、溶融ガラス１１１に直接的には接触しない頂部壁部分１０３、および溶融ガラスに直接的に接触する側部壁部分１０５を備えた清澄化槽内における溶融ガラスの清澄化ステップを含み、頂部壁部分１０３が温度Ｔ（頂部）を有し、側部壁部分１０５が温度Ｔ（側部）を有し、かつ、Ｔ（頂部）−Ｔ（側部）≦１０℃であるガラス清澄化システム。Ｐｔ及び／又はＰｔ・Ｒｈ合金等の貴金属から作製された金属製ガラス清澄化槽を備えたガラス清澄化システム。【選択図】図１
