Brighter and bluer than Cadmium Green, it was favoured by the French Impressionists. The original, no longer made, was arsenic-based and very toxic. Classification: Inorganic, Cadmium Chemical Composition: Cadmium (II)-sulfide 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 used in oil and watercolour forms. It cannot be mixed with copper-based pigments. A clean Cadmium Orange is created when Cadmium Yellow is mixed with Cadmium Red. 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. Classification: Organic Chemical Composition: Polychlorinated copper (II) phthalocyanine Properties Phthalo Green is a transparent, cool, bright, high-intensity colour used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has pigment properties and permanence similar to Phthalo Blue. It is slow drying and an excellent base colour for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense, mixes well, and can emphasize mineral colours in various tints. However, its tinting strength is very high so that it can overpower other colours. This pigment most closely resembles the discontinued and toxic Verdigris. Permanence Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. Due to their stability, they are currently used in inks, coatings, and many plastics and are considered a standard pigment in printing ink and the packaging industry. Toxicity Phthalo Green has no significant hazards but contained PCBs (polychlorinated biphenyls) until 1982. History This bright blue-green was developed in 1935 and has been used since 1938. 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 that is useful in all techniques and the best all around white. Its masstone is neither warm nor cool, placing it 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 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 rare. 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. Classification: Synthetic Inorganic Chemical Composition: Zinc sulfide 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 decreases. 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 ultraviolet light and is also used in the manufacture of fluorescent paints.R&F Encaustic Paint Block - Veronese Green, 40 ml
