As part of a very colorful and interesting paint history, Richeson Oils , the Shiva Series are a superior range of oil paint that is made right here at our factory in Wisconsin. Only pure, artist-grade dry pigments, ground to each one s own correct degree of fineness and then formulated individually under exacting laboratory controls are utilized. They are guaranteed to be permanent, free from darkening, yellowing, fading and cracking, and are bound with the finest grade of alkali-refined linseed and safflower oil available. Each tube receives a hand painted label. Professional artist oils should always have a hand painted label as printed labels do not offer the most accurate representation of color to the artist s eye. Produced in small batches to control quality.
