There's definitely a difference between super white glass and regular glass, but it seems more people are using regular glass these days.
Super white glass has less impurities, lower iron content, more transparent, and looks whiter. Due to iron impurities in ordinary glass, some of them are greenish (the greenish ones are obvious when seen from the side). Ordinary volt-glass and super white are also distinguishable on the front, after all, super white transparency is much higher, and the thicker the more obvious.
Abroad, super white glass is mainly used in high-grade building, high-grade glass processing and the field of solar photovoltaic curtain wall and high-grade furniture, decorative glass, imitated crystal products, glass lamps and lanterns, precision electronics industry (photocopiers, scanners), special construction etc. Super white glass and common glass, the price will be much more expensive, because the cost is more expensive, but also not in the domestic popularity.
