Ochre
| #cc7722 |
Ochre is a color, usually described as golden-yellow or light yellow brown. As a painting pigment it exists in at least three forms:
- yellow ochre, Fe2O3 • H2O, a hydrated Iron oxide
- red ochre, Fe2O3, obtained by heating yellow ochre
- brown ochre (Goethite), also partly hydrated iron oxide (rust)
Ochre was one of the first pigments to be used by human beings. Pieces of hematite, worn as though they had been used as crayons, have been found at 300,000 year old Homo heidelbergensis sites in France and Czechoslovakia. Neandertal burial sites sometimes include ochre as a grave good. The oldest evidence of mining activity, at the "Lion Cave" in Swaziland, is a 43,000 year old ochre mine.
