Industrial pigments
Iron oxideIron oxides are pigments. In their natural state they are known as ochres. They exist in different shades, the colour depending on the chemical structure of the oxide (yellow, red, black, brown, green, etc.). Synthetic pigment shades are more vivid than those of the natural pigments. Pigment colour arises from the effect of light absorption. Only non-absorbed light will be diffused by the material and will determine its colour. |
