About this product range

AlkydPro Fast-Drying Alkyd Oil Colors are artist's colors for the 21st century. Because AlkydPro Colors dry much quicker than traditional oil paints (within 20 hours), artists can complete paintings in a fraction of the time. The quick drying time also allows more creative freedom for artists who travel, paint plein air, or work in layers. The binder used in AlkydPro Alkyd Oil Colors is a sunflower oil alkyd resin. Because they contain no linseed oil, AlkydPro Oil Colors won't yellow, crack, or dull over time. At the same time, every color offers a high pigment concentration and the buttery feel that is consistent with professional-quality paints. The high pigment concentration also means that colors are purer, and a larger tube size means paints stretch further, ensuring a better value for the artist. AlkydPro Alkyd Oil Colors are compatible with traditional oils, mediums, mineral spirits, and turpentine, as well as with other alkyds. They also can be used to speed the drying time of oil paints. They contain no fillers, adulterants, or opacifiers. AlkydPro Alkyd Oil Colors dry to a brilliant, flexible finish and retain their color intensity after drying. Made in the USA.

Properties
Raw Sienna is a moderately dull deep earth yellow with medium tinting strength and excellent transparency. It is one of the basic permanent artists' pigments and is made from a form of limonite clay whose yellow-brown color results from ferric oxides. Raw Sienna is preferable to Yellow Ochre for creating flesh tones, due to its higher subtlety of color when mixed with white. It creates a bright Ochre when mixed with Cadmium Yellow and creates greens and grays when mixed with Ultramarine. Raw Sienna dries quickly.
Permanence
Raw Sienna has good permanence.
Toxicity
Raw Sienna has no significant hazards.
History
Raw Sienna has been used as a pigment since prehistoric times, although its current name came about during the Renaissance. It comes from the city of Siena, in Italy, and is short for terra di Siena, meaning earth of Siena. Sienna was famous for the mining and production of earth pigments from the Renaissance until World War II. Due to the depletion of clay deposits in Tuscany, Italian siennas now come from other areas, including Sicily and Sardinia.
