Historically, Cassel earth was based on lignitic earth or earth containing as much as 60% brownish-black coal (an intermediate between peat and bituminous coal). Rublev Colours Cassel Earth is made from a blend of natural black iron oxides and umber (iron and manganese oxides) from Italy and Cyprus. This particular blend, carefully blended, closely resembles the historical pigment in mass tone, opacity, and tinting strength. Historical Cassel earth was a fugitive pigment (that is subject to fading in light). Rublev Artists Oils Cassel Earth, on the other hand, is lightfast.

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 web site 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, because of the wide variance in color monitors, the results 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 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.
