Gamblin 1980 Oils - PG7-Phthalo Green (Polychlorinated copper(II) phthalocyanine); PG18-Viridian (Hydrated chromium(III)-oxide dehydrate)

Viridian: First synthesized in 1859, nontoxic Viridian replaced Verdigris and Emerald Green as a glazing colour by the turn of the 20th century. It has good tinting strength; its tint muted like colours of the natural world.

Pigment Composition and Permanence: 

Pigment Name: PG7-Phthalo Green

Pigment Type: Organic

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 hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue.

It is slow drying and an excellent base colour for mixing a range of bright greens.

Phthalo Green is considered an excellent alternative to Viridian because it is intense and mixes well, and can be used to emphasize mineral colours in various tints. However, its tinting strength is very high so 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 it contained PCBs (polychlorinated biphenyls) until 1982.

History

This bright blue-green was developed in 1935 and has been used since 1938.

 

Pigment Composition and Permanence: 

Pigment Name: PG18-Viridian

Pigment Type: inorganic

Properties

Viridian is the standard green and is stable, robust, and cold with an emerald green undertone. It has a transparent hue, good tinting strength, a dark masstone that can be almost black at full power, and a slow drying time in oil form.

Viridian is commonly replaced by the darker, more saturated, and staining Phthalo Greens, but its properties make it a necessary part of the palette of an experienced landscape painter.

Permanence

Viridian has excellent permanence, except in high-temperature work, and is highly valued as a glazing colour.

Toxicity

Viridian is slightly toxic.

History

Viridian's name comes from the Latin Viridis, meaning green. The process for manufacturing Viridian, or Transparent Oxide of Chromium, was patented by Guignet in Paris in 1859.

However, it was discovered by Pannetier and Binet in 1838. Viridian replaced Verdigris, which was reactive and unstable, and Emerald Green, which was a poisonous copper aceto-arsenite used as a rat poison in the sewers of Paris.
