All
ochres are non-toxic, and can be used to make oil paints that dry
quickly and cover surfaces thoroughly. They are found throughout
the world in many shades. Many sources consider the best brown
ochre to come from Cyprus, and the best yellow and red ochre from
Roussillon, France. All are prehistoric, and are some of oldest
pigments used.
