I want to know the answer to the following question:
What can prevent a green color in glass?
All the background I'm provided with is that "Ordinary soda-lime glass appears colorless to the naked eye when it is thin, although iron(II) oxide (FeO) impurities of up to 0.1 wt% produce a green tint, which can be viewed in thick pieces or with the aid of scientific instruments.". Is that enough to answer the question?
Answer: no
