Product Description
Rublev Colours Italian Brown Ocher is a semi-transparent brown with good tinting strength, medium grained that makes yellow biege half tints. Our natural earth is from quarries in northern Italy.
Hydrated iron oxide is the principle coloring agent in ochers. This color is based on the natural mineral goethite associated with varying proportions of other minerals, such as clay, chalk and silica. They differ from other red ochers in that they contain water. In other words, the iron to which they owe their color is hydrated iron oxide. Natural ochers are absolutely permanent and have good covering power.
