Yellow Iron Oxide

Pigment code
PY42
Chemical name
iron(III)-oxide, hydrated
Chemical formula
Fe2O3 • H2O
Properties
Yellow Ochre provides artists with earthtones from cream to brown. It has good hiding power, produces a quick drying paint, and can be safely mixed with other pigments. Its transparency varies widely from opaque shades to more transparent ones, which are valued for their use as glazes. If gypsum is present, Yellow Ochre is not suitable for frescoing. (See Brown Ochre, PY43.) PY42 is made from synthetic iron oxides. PY43 is made from natural iron oxide.
Permanence
Yellow Ochre has excellent permanence because ochres are some of the most permanent pigments available.
History
Ochre comes from the Greek word ochros, meaning pale yellow. It was one of the first pigments to be used by human beings, and evidence of its use has been found at 300,000 year old sites in France and the former Czechoslovakia.
Description
Chamois, Iron Yellow, Mars Orange, Mars Yellow, Minette, Ochre, Sil, Yellow Earth, Yellow Ochre, Yellow Oxide. Varieties of Yellow Ochre include Brown Ochre, Flesh Ochre, Roman Ochre, Spruce Ochre, and Transparent Gold Ochre.

Phthalo Blue

Pigment code
PB15:3
Type
organic
Chemical name
beta copper phthalocyanine
Chemical formula
C32H16CuN8
Properties
Phthalo Blue PB15:3 is a structural variant of Phthalo Blue PB15 that produces more greenish tones.
Permanence
Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. 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 Blues have no significant hazards, although those made before 1982 contained some PCBs (polychlorinated biphenyls).
History
Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.

Dioxazine Violet

Pigment code
PV23
Type
organic
Chemical name
carbazole dioxazine
Chemical formula
C34H22Cl2N4O2
Properties
Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when it is used at full strength. Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple. PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in red shade, blue shade, and so forth.
Permanence
Dioxazine Violet has good lightfastness. There may be some concern about it fading or shifting in color in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.
History
Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Description
Dioxazine Purple, Chromothal Violet, Mauve, Carbazole Violet.
