Ultramarine blue For industrial use, Lazulite is produced synthetically by a process developed in France in the early 19th century. The blue powder has also been produced by Holliday Pigments in the UK since 1884. This is a world center for standard pigments and works in tandem both in France. Holliday Pigments supplies more than 50% by volume and 70% by value of all the Ultramarine blues used in the world.

 Ultramarine blue Because of its contrasting blue color with yellow, it was initially popularly used as a bleaching agent in laundry. Today, blue pigment is used mainly in high value applications, such as cosmetics, plastic materials, paints, printing inks and fine art goods. By chemical modifications, the blue pigment is also modified to produce unique colors such as purple and pink.

 Ultramarine blue This pigment is an inorganic material that is physically and chemically stable in most environments. It has many advantages:

* Does not react with polymers, hydrocarbon oils and fats.

* No physical impact of the heating process when forming the mold.

* Colorant does not move.

* Can be mixed with many traditional and modern carriers, so it is very safe, can be used in plastic materials in contact with food to produce food and cosmetics, also meets the requirements of pharmaceuticals. European and American Dictionary, Regulations for use in medical devices.

* Approved as safe in the manufacture of plastic children's toys.

 Ultramarine blue The chemical nature of this pigment is very special. It is a sodium aluminosulfosilicate with a lattice structure. The unique blue color appears due to the cracking process of the sulfur molecule. This is usually an eight-atom ring, but in pigments it is broken down into a three-atom wire and inserted into the lattice. This causes the sulfur to be dissociated from the medium, but at the same time gives a highly reactive free electron. This makes it possible to absorb the yellow wavelengths and produce the characteristic blue color.
