Product name : Ultramarines

Characteristics and Application :

Ultramarine is a blue pigment consisting primarily of a double silicate of aluminium and sodium with some sulfides or sulfates, and occurring in nature as a proximate component of lapis lazuli. In the past, it has also been known as azzurrum ultramarine, azzurrum transmarinum, azzuro oltramarino, azur d'Acre, pierre d'azur, Lazurstein.

The pigment color code is P. Blue 29 77007. Ultramarine is the most complex of the mineral pigments, a complex sulfur-containing sodio-silicate (Na8-10Al6Si6O24S2-4), essentially a mineralized limestone containing a blue cubic mineral called lazurite (the major component in lapis lazuli). Some chloride is often present in the crystal lattice as well. The blue color of the pigment is due to the S3− radical anion, which contains an unpaired electron.

An environment friendly product, Ultramarine Blue Pigment is a very safe, non-hazardous and natural indigo dye with a variety of applications worldwide. It has a synthetic manufacturing process with a possibility for close control over its physical, chemical and color characteristics that enable the production of various types of these blue pigments.
