Glass Colour

Container glass can be made in many different colours, with the most common colours being flint (clear); amber or brown, produced by the addition of iron-sulphide; various shades of green, produced by adding iron-chromite, and light blue, produced with cobalt. Red glass is produced by adding cadmium, cuprous oxide, or gold. These are shown in the pie chart as minor ingredients.
