Pigment Information
This color contains the following pigments:
PY42-Yellow Iron Oxide
PR107-Antimony Vermilion
Pigment Name
PY42-Yellow Iron Oxide
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.
Toxicity
Yellow Ochre is non-toxic unless it contains manganese.
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.
Pigment Name
PR107-Antimony Vermilion
Pigment Type
inorganic
Chemical Name
antimony trisulfide
Chemical Formula
Sb2S3 or Sb2S5 or Sb2S3 + Sb2O3
Properties
Depending on conditions, the pigment can range from orange to deep red. It is insoluble in water. Because it is heat resistant, it has been used to color glass.
Permanence
Lightfast and permanent, although it blackens on contact with lead pigments.
Toxicity
Antimony Vermilion is highly toxic by inhalation and ingestion. Skin contact can cause allergies and ulcers. It reacts explosively with some organic materials.
History
Antimony trisulfide was synthesized in 1842, and was used in artist pigments during the 19th century. Antimony Vermilion developed a bad reputation in the 19th century because it reacted with lead. Antimony trisulfide pigments have been replaced by cadmiums.
