Pigment Name: PY37-Cadmium Yellow

Classification: Synthetic Inorganic, Cadmium

Chemical Composition: Cadmium (II)-sulphide

Properties

Cadmium Yellow is brilliant, dense, and opaque, with good tinting strength and high hiding power. It is the artist’s principal bright yellow and is available in light, medium, and dark shades. The deeper shades appear deep orange and have the greatest tinting strength. It is slow-drying in oil form and is used in both oil and watercolour form. It cannot be mixed with copper-based pigments. When Cadmium Yellow is mixed with Cadmium Red, a clean Cadmium Orange is created. Hues vary by brand. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colours, cheaper, and non-toxic. Cadmium Yellow is usually available in a pure grade or a cadmium-barium mix. This mix has the same permanence with a lower tinting strength.

Permanence

Cadmium Yellow is lightfast and permanent in most forms, but like most cadmium colours, it will fade in fresco or mural painting. The deeper shades are the most permanent. The pale varieties have been known to fade with exposure to sunlight.

Toxicity

Cadmium Yellow is a known human carcinogen. It can be hazardous if chronically inhaled or ingested.

History

Cadmiums get their names from the Latin word cadmia, meaning zinc ore calamine, and the Greek word kadmeia, meaning Cadmean earth, first found near Thebes, the city founded by the Phoenician prince Cadmus. Metallic cadmium was discovered in 1817 by Friedrich Strohmeyer. Oil colours were first made from Cadmium Yellow pigments in 1819, replacing toxic Chrome (lead) Yellows. However, their production was delayed until 1840 due to the scarcity of cadmium metals. Landscape painters, such as Claude Monet, preferred Cadmium Yellow to the less expensive Chrome Yellow because of its higher chroma and greater purity of colour.

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

Pigment Name: PR101-Red Iron Oxide

Classification: Synthetic Inorganic, Earth

Chemical Composition: iron oxides (synthetic), iron oxide, silica, alumina, lime, and magnesia or hydrated iron oxide

Properties

Red iron oxide varies in hue and transparency, depending on hydration and slight impurities. Indian Red is a slightly duller, deep brick hue with a bluish undertone. It is very dense and opaque, with excellent tinting strength and covering power. It is dependable when mixing with all other permanent pigments and yields good flesh tints when mixed with Zinc White. It is the synthetic version of PR102, a pigment made from earth reds or natural red iron oxides, and the names applied to PR101 and PR102 often overlap. Synthetic red iron oxides have mostly replaced natural red iron oxides and are brighter, more robust, more refined, and more permanent. Indian Red is the highest grade bluish shade. Light Red, English Red, and Venetian Red are yellowish shades. Mars Violet is a dull and subdued bluish or purplish oxide.

Permanence

Red iron oxide is very lightfast with excellent permanence.

Toxicity

Red iron oxide has no significant hazards.

History

Natural red iron oxide comes from the mineral ore hematite, called bloodstone by the ancient Greeks from the word hema, meaning blood. It is one of the oldest pigments, has been used by every major civilization, and was an essential mineral for medieval alchemists. It was not widely used in artists' materials until the 17th century and was not produced in large quantities until the 18th century.

Pigment Name: PO20-Cadmium Orange

Classification: Synthetic Inorganic, cadmium

Chemical Composition: Cadmium sulphide and cadmium selenide

Properties

Cadmium Orange was the first true orange and was made by mixing Cadmium Yellow with Cadmium Red. It is a pure hue with excellent opacity and low toxicity compared with its predecessors. It also has very high hiding power. The deeper shades possess the greatest tinting strengths. Only the highest grades contain pure Cadmium Orange without barium mixed in it. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colours, cheaper, and non-toxic.

Permanence

Cadmium Orange has excellent permanence, but like many cadmium pigments, it will fade in fresco or mural painting. The deeper varieties of this pigment are the most permanent. The paler varieties have been known to fade when exposed to sunlight.

Toxicity

Cadmium Orange is a known human carcinogen. It is highly toxic if inhaled and slightly toxic if ingested.

History

Cadmiums get their names from the Latin word cadmia, meaning zinc ore calamine, and the Greek word kadmeia, meaning Cadmean earth, first found near Thebes, the city founded by the Phoenician prince Cadmus. Metallic cadmium was discovered in 1817 by Friedrich Strohmeyer. It was used sparingly after its discovery due to the scarcity of cadmium metal.

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.
