SUMMARY
The green tint observed in glass when viewed from the side, as opposed to its clear appearance from above, is primarily due to the presence of iron impurities in the sand used to manufacture the glass. Iron ions absorb light in the red and blue parts of the spectrum, allowing predominantly green light to be transmitted. This effect is more pronounced when viewing the glass edge-on, as the increased thickness of the glass enhances the absorption characteristics. The behavior of iron in the glass lattice contributes to this phenomenon.
