    Rublev Colours Bone Black, also known as ‘bone char’ or ‘animal charcoal,’ is produced by charring animal bones. The bones are heated to high temperatures without oxygen. It consists mainly of calcium phosphate and a smaller amount of carbon. Ivory black is an artist’s pigment formerly made by grinding charred ivory. Ivory is no longer used because of the expense and because animals that are natural sources of ivory are subject to international control as endangered species. Today, ivory black is considered a synonym for bone black. Among artist pigments, ivory black is considered a better grade than bone black, consisting of 15 percent or more carbon. We use only the best grade of bone char containing at least 18 percent carbon. Rublev Colours bone char oil paint is named ‘Bone Black’ because we use the name of the actual pigment for our colors.

    Some 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 on this website are only approximations of the actual color of the oil paint. We have carefully matched the color in these pictures on calibrated color monitors to the actual color. However, your results may vary because of the wide variance in color monitors.

    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 mils (0.006 inches) thickness applied to a standard test card to examine color consistency, opacity, and other qualities. The drawdowns show the color's 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 is scraped to show undertones.
