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.”
Hoover Color’s 320BS is one of the highest quality Burnt Siennas on the market today. It combines ease of dispersion with high color strength. Burnt Siennas are one of the most versatile pigments on the market today. They are used in almost any application, but are most often recognized as one of the prime pigments used for stains and glazes in wood coatings, because of their transparency and warm red tone. If you’re creating a wood stain in the shade of cherry, mahogany or rosewood, then Burnt Sienna is a prime choice for your color formulation work.
