Zusammenfassung:	To provide a method for manufacturing a glass product, capable of avoiding and/or minimizing the problem of forming bubbles.SOLUTION: The problem is solved by a method of manufacturing a glass product having less than 0.2 of a molar ratio of Fe2+ to Fe3+ and a glass product having a low CO2 solubility and/or a reduced total carbon content. The CO2 solubility is a CO2 bar-1 having molecules of less than 5×1019 per 1 cm3 at 1100°C; and the glass product has less than 0.2 of a ratio of Fe2+ to Fe3+; and further the glass product is excellent in bubbles having a number and/or size reduced in the glass product.SELECTED DRAWING: Figure 1 【課題】気泡の形成の問題を回避および／または最小化するガラス製品の製造方法を提供する。【解決手段】前記課題は、Ｆｅ2+のＦｅ3+に対するモル比の値０．２未満を有するガラス製品の製造方法、および低いＣＯ2溶解度および／または低減された総炭素含有率を有するガラス製品であって、前記ＣＯ2溶解度が、１１００℃で１ｃｍ3あたり５×１０19未満の分子のＣＯ2ｂａｒ-1であり且つ前記ガラス製品がＦｅ2+のＦｅ3+に対する比の値０．２未満を有する、前記ガラス製品によって解決される。前記ガラス製品はさらに、前記ガラス製品内での低減された数の気泡および／または低減された大きさの気泡によって優れている。【選択図】図１
