Gamblin 1980 Oils - PG17-Chromium Oxide Green

Gamblin’s approach is different. 1980 colours contain pure pigments, the finest refined linseed oil, and marble dust (calcium carbonate). Since oil painting began, these three ingredients have made more affordable colours.

Painters experience true colours without homogenized texture or muddy colour mixtures. Gamblin's approach to using traditional raw materials and processes ensures that artists experience the luscious working properties they expect from their oil colours.

Chromium Oxide Green: Land painters use a muted, earthy, opaque green. Chromium Oxide Green is an entirely opaque, dull, dense, willow or pale green. It has an average drying time and a low tinting strength. It is relatively flexible in oil form.

PIGMENT COMPOSITION AND PERMANENCE

• Pigment Name: PG17-Chromium Oxide Green (Anhydrous chromium sesquioxide)
• Pigment Type: inorganic

PROPERTIES

Chromium Oxide Green is an entirely opaque, dull, dense, willow or pale green. It has an average drying time and a low tinting strength. It is relatively flexible in oil form and is suitable for all purposes and mediums.

This pigment is less versatile in mixtures than Viridian and Phthalocyanine Green but mixes well with other colours without overpowering them.

PERMANENCE

Chromium Oxide Green has excellent permanence, even at high temperatures.

TOXICITY

Chromium Oxide Green is slightly toxic. Evidence of Chromium (III) carcinogenicity is inconclusive. Chromium (III) salts appear in greenish pigments such as PG17. Chromium (VI) salts, which appear in yellowish pigments, have been proven to cause cancer.

HISTORY

Louis-Nicolas Vauquelin discovered the element chromium in lead chromate in 1797. It began to be used as an enamel and ceramic colour in 1809, but because of its cost, its use as a pigment was limited until 1862. It is the most commonly used green for military camouflage because it appears the same shade as living foliage under infrared light.
