"While regular clear glass does not have substantially high iron content, it is higher than low iron glass. Due to this higher iron content, clear glass has a greenish tint to it."

Why isn't a magnet attracted to glass?

Iron is magnetic only as alpha iron. Ferric oxide doesn't count, and that's the form that seems to appear in glass.
