Van Dyke Brown is a transparent brown pigment made from organic humic substances like soil, peat, or brown coal. Its transparency makes it more ideal for glazing than umbers and ochres. True Van Dyke Brown can turn dark or fade upon prolonged exposure to sunlight and has a tendency towards grey when mixed with whites. It is no longer used by artists concerned with permanence, and it has been replaced by mixtures containing Transparent Brown and Burnt Sienna.
Van Dyke Brown was impermanent in its original varieties, but modern pigments by this name are generally more permanent.
Van Dyke Brown has no significant hazards unless contaminated with silica.
The discovery of this pigment dates from the late 16th or early 17th century. It was renamed in the 18th century after the great Flemish painter Anthony Van Dyke, who loved this dark, transparent color. Van Dyke Brown is made from treated Cassel earth with 80-90% organic materials and iron, alumina, and silica.
