Discover the vibrant world of ultramarine blue pigment. This guide for artists delves into the history, composition, and techniques of using ultramarine blue, a pigment cherished for its depth and brilliance in art.
Ultramarine is a blue pigment consisting primarily of a zeolite-based mineral containing small amounts of sulfur. Ultramarine is one of the most complex of the mineral pigments, composed of the blue mineral lazurite, which is the major component of the rare and semi-precious stone lapis lazuli. The mineral occurs in nature as a product of limestone metamorphism. It is typically associated with calcite, pyrite, diopside, humite, forsterite, hauyne, and muscovite minerals, sometimes found in lava as a by-product of volcanic eruptions.
