About this product range

Tested and approved by professionals, for professionals, Grumbacher Pre-Tested Professional Oils have been one of America's favorite oil paints since 1905. Recently reformulated, the line now includes stronger, purer cadmiums and exciting contemporary colors.

Grumbacher Pre-Tested Oils are made with the finest pure pigments milled in select alkali-refined linseed oil, with the exception of the Whites described below. All 90 colors are highly pigmented, with tinting strength equal to or better than the leading professional brands. Pre-Tested Oils offer high chroma, superior tinting strength, excellent adhesion, outstanding working properties, the utmost lightfastness, and archival permanence.

Superba White is a smooth, buttery, heavy-bodied white ground in non-yellowing poppy seed oil. Superba is unaffected by exposure to light, freely intermixable with other colors, and offers enhanced opacity and tinting strength.

Titanium White is a permanent, heavy-bodied, versatile, opaque, pure white that is neutral in hue. It's ideal for applications where great opacity is required, and is considered the strongest tinting white.

Soft Titanium White is a permanent soft-bodied, opaque, non-yellowing Titanium White that is ground in poppy seed and sunflower oils, rather than linseed oil. These oils do not yellow with age, as does pure linseed oil. Soft Titanium White is also recommended for fluid wet-in-wet techniques.

Zinc White is a permanent, heavy-bodied, semi-opaque, cool white. It's designed especially for brilliant clear tints with all oil colors, and is excellent for glazing.

Phthalo Green

Pigment code
PG36
Type
organic
Chemical name
polybromopolychlorinated copper(II) phthalocyanine
Chemical formula
C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
Properties
Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. Pigment PG36 differs from PG7 in that a portion of the chlorine atoms are replaced with bromine atoms, which are reactively similar, but cause a yellow shift that is especially noticeable in mixtures. Phthalo Green has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. 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. They are currently used in inks, coatings, and many plastics due to their stability 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 in use since 1938.
