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 312BS balances the need of product quality and cost. This pigment disperses on a high speed equipment to a lower level than Hoover Color’s “Best” grades, but can still be media milled to desired specifications. Burnt Siennas 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.
