Pigment information

General reference notes about pigments can describe other media (such as oil). They do not verify this product’s exact formulation or behavior.

Lamp Black

Pigment code
PBk6
Type
inorganic
Chemical name
carbon
Chemical formula
C
Properties
Lamp black is a very opaque, heavily staining black pigment that does not have much covering power. It is typically the most opaque black in watercolor form. Though a very pure black, it tends to muddy slightly in mixtures, is one of the slowest drying pigments in oils, and should not be used under other colors.
Permanence
Lamp Black is very lightfast and absolutely permanent. It is used in all techniques in permanent painting.
Toxicity
Lamp Black is slightly toxic by skin contact and inhalation. It is a possible human carcinogen.
History
Lamp Black is a carbon based black traditionally produced by collecting soot (known as lampblack) from oil lamps. It is the black found in Egyptian murals and tomb decorations and was the most popular black for frescoing until the development of Mars Black.
Description
Carbon Black, Channel Black, Oil Black, Vegetable Black. Flame Black is an impure version of Lamp Black.

Lithopone

Pigment code
PW5
Type
inorganic
Chemical name
coprecipitated zinc sulphide and barium sulphate
Chemical formula
Zn + BaSO4
Properties
Lithopone is a low tinting strength, semi-transparent white pigment that is often used as a filler or extender in other colors, or as the base for laked pigments.
Permanence
Lithopone is absolutely permanent and lightfast.
Toxicity
Lithopone is not toxic.
History
Lithopone was discovered by G.F. de Doubet in 1850. It was developed commercially in the 1870s as a substitute or supplement for lead carbonate, to overcome the many shortcomings of white lead pigment, including toxicity, poor weathering, and darkening in the presence of sulfur compounds. It is used most often in interior paints and enamels. Its use as a white pigment has been superceeded in many applications by titanium dioxide.
Description
Transparent White.

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.
