Cadmium-Barium Orange

Pigment code
PO20:1
Type
inorganic, cadmium
Chemical name
cadmium selenosulfide lithopone
Chemical formula
CdS + CdSe + BaSO4
Properties
Cadmium Orange PO20:1 shares the properties of Cadmium Orange PO20, except that it has lower tinting strength. 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 greatest tinting strengths are possessed by the deeper shades. 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 lightfasness to the cadmium colors, cheaper, and non-toxic.
Permanence
Cadmium selenosulfide lithopone has excellent lightfastness. It shares the permanance of pure cadmium selenosulphide (Cadmium Orange PO20). However, cadmium colors are not recommended for outdoor use, or for mural and fresco painting.
Toxicity
Cadmium is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested. Barium sulfate is extremely insoluble in water, and thus is not biologically active. It is used medically as a contrast medium in radiological procedures
History
Cadmium Orange PO20:1 is cadmium orange pigment that contains 15% or more barium sulfate. It is used to create a fuller spectrum of reds and oranges from cadmiums, and also to create a less expensive alternative to PO20. 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.
