R&F Oil Pigment Stick, Neutral White 38ml

R&F Pigment Stick - Neutral White, 40 ml

Alongside Titanium-Zinc, it looks almost brown. With spectrum colours, it looks white and does not ten to “pop” out like Titanium-Zinc. Not a good mixing white.

Pigment Name: PW6-Titanium White

Classification: Synthetic Inorganic

Chemical Composition: Titanium dioxide

Properties

Titanium White is the most brilliant of the white pigments. It is considered an all-purpose oil colour 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 watercolour 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 do not indicate that it is absorbed biologically, even after long periods of exposure. The primary safety concern is with the inhalation of fine pigment dust particles.

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 the ancestor of the Titans, and the Greek word tito, meaning day or sun.

Pigment Name: PW7-Zinc Sulphide White

Classification: Synthetic Inorganic

Chemical Composition: Zinc sulphide

Properties

Zinc Sulphide White is a semi-transparent yellowish-white pigment. Zinc sulphide and zinc oxide (PW4) are often combined to create a more natural white colour. Transparency increases as particle size decrease. When slight impurities are added, zinc sulphide has phosphorescent and electroluminescent properties. It is often used to manufacture fluorescent or glow-in-the-dark paints.

Permanence

Zinc Sulphide White has excellent permanence and lightfastness.

Toxicity

Zinc Sulphide is non-toxic, but ore deposits often contain lead. Traces of lead and other impurities may be present in pigment powders. Ingestion is not recommended.

History

Zinc sulphide, when combined with slight impurities, has phosphorescent properties. It is often used for invisible ink that glows with exposure to ultraviolet light. Zinc sulphide is used in the manufacture of fluorescent paints.
