Rutile One of two titanium ores suitable for creating the pigments for titanium white paint used by artists. The other type of Rutile is the titanium ore called Ilmenite. The compound is not only used in the art for paints in tubes. It is also used in ceramic glazes though here it creates more of a yellow or ivory finish. Rutile is a mineral composed primarily of titanium dioxide, TiO2. It is the most common natural form of TiO2. Three rarer polymorphs of TiO2 are known in the form of Anatase (Octahedrite), a tetragonal mineral of pseudo-octahedral nature. Next, there is Brookite, an orthorhombic mineral.
