Historical use in art and culture


Prehistory

Yellow and red ochre pigment was used in prehistoric and ancient times by many different civilizations on different continents. Evidence of the processing of ochre to a lesser extent, in Africa and Europe has been dated by archaeologists to 300,000 years ago, evidence of use in Australia is dated to 50,000 years ago, and new research has uncovered evidence in Asia that is dated to 40,000 years ago.

, and he was fascinated by the cliffs of red and yellow clay in the region. He invented a process to make the pigment on a large scale. First the clay was extracted from open pits or mines. The raw clay contained about 10 to 20 percent ochre. Then he washed the clay to separate the grains of sand from the particles of ochre. The remaining mixture was then decanted in large basins, to further separate the ochre from the sand. The water was then drained, and the ochre was dried, cut into bricks, crushed, sifted, and then classified by colour and quality. The best quality was reserved for artists' pigments. In
