TiO2

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all purpose oil color useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it somewhere between Lead White and Zinc White. It is less prone to cracking and yellowing than Lead White, but it still yellows easily. Titanium White dries slowly in oil form, more slowly than Lead White but more quickly than Zinc White. It is opaque in oil and acrylic forms and semi-opaque in watercolor form. This pigment has good chemical stability, and its tinting strength is superior to both Lead White and Zinc White.

Permanence

Titanium White has excellent permanence and lightfastness.

Toxicity

Titanium dioxide is highly stable and is regarded as completely non-toxic. Animal studies give no indiciation that it is absorbed biologically, even after long periods of exposure. The primary safety concern is with inhalation of fine pigment dust particl

History

Titanium is the ninth most abundant element in the Earth's crust, however mineral deposits that are economical to mine are less common. Titanium dioxide was first discovered in 1821, although it could not be mass produced until 1919. Widespread use of the pigment began in the 1940s. Since that time, it has become the most commonly used white pigment. The name comes from the Latin word Titan, the name for the elder brother of Kronos and ancestor of the Titans, and from the Greek word tito, meaning day or sun.

Buff Titanium is lightfast and permanant.

Toxicity

Titanium dioxide and iron oxide are naturally occuring and are abundant in the Earth's crust. Both are considered non-toxic. Particle sizes tend to be larger in Unbleached Titanium than for titanium dioxide pigments used in white paints.

History

Titanium dioxide often occurs in nature with iron oxide. Buff or unbleached titanium is a natural mineral form of titanium dioxide. A variety of processes are used to produce buff or unbleached titanium. Some manufacturers may add synthetic iron oxides to a titanium base, while others use naturally occuring titanium ores that contain impurities. In this respect, Buff Titanium or Unbleached Titanium is a color that that may vary from one manufacturer to another.
