Gamblin 1980 Oils - PG7 Phthalo 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.

Phthalo Green: A dark bluish green more closely resembles Verdigris than Viridian. First manufactured in 1927, Phthalo Green has high tinting strength and transparency. Consider using Phthalo Emerald, a warmer and more natural-looking colour.

PIGMENT COMPOSITION AND PERMANENCE

• Pigment Name: PG7 Phthalo Green (Chlorinated polychlorinated copper(II) phthalocyanine)
• 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 in which most 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 an excellent alternative to Viridian because it is intense, mixes well, and can be used to 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.
