Common pigment for glass bottles: chromite powder
Yes, chromite powderis one of the most commonly used pigment for green glass bottles (especially beer bottles, wine bottles, etc.).
The main component of chromite powder is Cr2o3. In the glass melt, chromium exists in the form of trivalent chromium, which makes the glass appear green.
Chromium concentration: The higher the concentration, the darker the green.
Basic glass composition: Iron will give the glass a yellow-green hue, and combining with chromium will intensify this yellow-green hue. This is why many beer bottles are the classic “amber green” or “yellow-green” color.
