Sartorius Red Earth Oil Paint
Sartorius Red is a semi-transparent brown-red with warm undertones, medium grain, moderate tinting strength, and brushes “long” in the direction of the brush stroke. Our red earth comes from quarries in Northern Italy.
Sartorius Red is a semi-transparent red ocher from Italy, consisting of red iron oxide, or ferric oxide, which is the principal coloring agent in red ochers, such as red Sartorius earth. This color is based on the natural mineral hematite, which is associated with varying proportions of other minerals such as clay, chalk, and silica. They differ from other ochers in that they do not contain bound water. In other words, the iron to which they owe their color is iron oxide, not hydrated iron oxide.

Notes
Some separation of pigment and oil may occur in Rublev Colours Artist Oils, and it is a natural process when no wax or stabilizers are added to the paint to prevent it.
All color swatches on this website are 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 due to the wide variance among color monitors.
Color Swatch Note: The color swatch was created with a thick application of color (left side) and a tint (right side) made with equal parts of color and titanium white, applied to acrylic-primed cotton canvas.
Drawdown Note: The image of the “drawdown” shows a premixed paint film 6 mils (0.006 inches) thick, applied to a standard test card to examine color consistency, opacity, and other qualities. The drawdowns show the full-color 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.
