Pigment Information

This color contains the following pigments:

PY1-Hansa Yellow G

PY13-Benzidine Yellow

PY43-Brown Ochre


Pigment Name

PY1-Hansa Yellow G

Pigment Type

organic, monoazo

Chemical Formula

C17H16N4O4

Properties

This Hansa yellow is a transparent yellow. It has great brightness and tinting strength and its drying time ranges from average to slow. Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colors like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colors.

Permanence

Hansa Yellow G has good permanence and lightfastness, particularly in the lighter shades.

Toxicity

Hansa Yellow pigments have no significant acute hazards, though chronic hazards have not been well studied.

History

Hansa Yellows were first made in Germany just before World War I from a series of synthetic dyestuffs called Pigment Yellow. Hansa Yellow G, introduced in 1910, was the first of these products to be commercialized. Hansa Yellow G was the standard yellow for printing inks until late in the 20th century, when stronger diarylide yellows began to replace it. It is still used a great deal in packaging, and for air drying paints.

Chemical Name

iron(III)-oxide, partly hydrated

Properties

Brown Ochre provides artists with earthtones from cream to brown and is a dull, dark variety of Yellow Ochre. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. The highest quality Brown Ochre comes from Cyprus, where it is yellow in its raw form and is roasted to get the deeper brown-red varieties that result when water is removed. (See Yellow Ochre, PY42/43.)

Permanence

Brown Ochre has excellent permanence.

Toxicity

Brown Ochre is non-toxic.

History

Ochre comes from the Greek word ochros, meaning pale yellow. It has been used since prehistoric times, and evidence of its use has been found in some of the earliest known cave paintings in Lascaux, France. It has also been called Goethite, after the German philosopher and mineralogist Johann Wolfgang von Goethe (1749-1832).
