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. It is very transparent.
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.

NotesSome separation of pigment and oil may occur in Rublev Colours Artist Oils and is a natural process when no wax or stabilizers are added to paint to prevent this from occurring.
All images of color swatches in this web site are only approximations of the actual color of the oil paint. We have taken every care to match the color in these pictures on calibrated color monitors to the actual color. However, because of the wide variance in color monitors the results you get may vary.
Color Swatch Note: The color swatch was created with a thick application (left side) of color and a tint (right side) made with equal parts of color and titanium white and applied on acrylic primed cotton canvas.
Drawdown Note: The image of the "drawdown" contains a pre-mixed paint film of 6 mil (0.006 inch) thickness applied to a standard test card for the purposes of examining color consistency, opacity and other qualities. The drawdowns show the color full strength (mass tone), on the left, and mixed in a 1:2 ratio with titanium white on the right. The bottom area of the drawdowns are scraped to show undertones.
