Industrial Uses
Ultramarine Blue is an inorganic pigment whose colour has been classified as Pigment Blue according to the Colour Index System. Chemically it is a synthetic form of Lazurit, sodium alumino-sulphosilicate. It is prepared by heating kaolin, sodium carbonate, sulphur and other inexpensive ingredients together.
The Ultramarine is an excellent white corrector that neutralizes yellowish shades. Moreover, when using Ultramarine Blue for this application, metamerism (change of colour in function of the illuminant) does not occur. This whitening effect is appreciated in many fields of application e.g. masterbatch, detergency, plastics, paints and more.
