Documented uses on record

During the Middle Ages, ultramarine was used by artists as the blue from over the sea. It was derived from the semiprecious stone, lapis lazuli, imported from Afghanistan. Since 1828 when it was first synthesized, the supply of the pigment has become abundant. Ultramarine pigments are used in plastics, paints, printing inks, paper, artist colors, laundry detergents (optical brightener), and toys.
