Ultramarine blue pigment, chemically known as Pigment Blue 29 (PB29), is a synthetic inorganic pigment with a brilliant blue hue derived from a complex aluminosilicate structure containing polysulfide groups. It is one of the most widely used blue pigments globally due to its exceptional heat stability, lightfastness, and non-toxic nature.
Historically, ultramarine was derived from lapis lazuli, a semi-precious stone found in Afghanistan. In 1828, French chemist Jean-Baptiste Guimet synthesized the first artificial ultramarine, making the pigment affordable and accessible to industries worldwide.
