Rublev Colours Red Sartorius Earth is a semi- transparent deep orange red with warm undertones, medium grained, high tinting strength and brushes "long" in the direction of the brush stroke.

Red iron oxide or ferric oxide is the principle coloring agent in red ochers, such as red Sartorius earth. This color is based on the natural mineral hematite associated with varying proportions of other minerals such as clay, chalk, and silica. They differ from other Ochres in that they do not contain water. In other words, the iron to which they owe their color is iron oxide, not hydrated iron oxide.
