Note: Anatase is a relatively uncommon yet very aesthetic form of titanium dioxide. It forms distinct and unique crystals, which are usually microscopic to very small, though a few localities have produced larger crystals. Anatase is polymorphous with the more common Rutile, as well as Brookite. It is often replaced entirely by Rutile, forming interestingly shaped Rutile pseudomorphs after Anatase. The name Anatase is derived from the Greek word anatasis, which means elongation, in allusion to its elongated crystal habit in relation to Rutile.
