The mineral pigment Ultramarine Blue by Nila Colori is chemically sodium polysulfide and aluminosilicate. Between the end of the XVIII and the beginning of the XIX century, it people began to realize that the blue color of lapis lazuli could be artificially produced. In the early decades of 1800 it was understood how this could be done and Ultramarine Blue thus began to be produced. The process is quite simple and involves non-toxic inorganic reagents. The final product is a aluminosilicate with sulfur and sodium entrapped in its lattice.
