Siennas are one of the oldest pigments used by mankind. These natural Iron Oxides are known for their durability and are considered a permanent pigment. Burnt Siennas build on the lightfast and chemical resistance of Raw Sienna and add improved heat stability. Raw Siennas are naturally occurring Iron-Hydroxides, which convert to Iron Oxides upon heat treating. This is how we get the term “Burnt Sienna.”
