Rublev Colours Barite is a transparent buff colored pigment ground in walnut oil. It is ideal for flesh tones where a soft, mixing buff color is needed to tone down whites and other colors.
Barite (baryte) is the natural barium sulfate mineral, other names in literature include 'heavy spar' and 'cawk.' The name comes from the Greek word barys, meaning heavy. The reason for the name is its density, 4.48 g/cm3, which is rather high for a mineral. Barite has an extremely low value of oil absorption and is chemically inert. Barites were one of the most important extender pigments in the 19th century. They were added to reduce the tinting strength of pigments, such as Prussian blue, and to improve the working qualities of a color.
Mix Rublev Colours Barite with other colors to reduce their tinting strength and to improve the handling qualities.
