Descripción
A permanent, reddish brown pigment that was originally prepared from a natural red ocher, but since the 18th century has been manufactured by calcining ferrous sulfate (copperas) with lime or calcium carbonate in a ratio of around 15-40% ferric oxide and 60-80% calcium sulfate. It is used in oil paints, house paints, and as a paper colorant.
