Pigments can be natural, earth pigments (hematite, Indian red, Venetian red) or synthetically prepared pigments (light red). All iron oxide reds are stable, permanent pigments with good tinting strength and are the primary colorant in ochers and siennas. The pigment was first manufactured in the early 18th century. Today it is often a furnace product made from steel-mill waste. ]]></note></mads>
