Item:284 600 178, Pigment: Recycled Iron Oxide PBr 6 (77499), Lightfastness: Excellent, Semi-Transparent, Non-staining, Granulating.
At full strength this deep umber is useful for warm shadows and dark values. Mixed with water, a brilliant granulating wash displays warm cinnamon tones with a darker pattern of granulation, using pigments from the earth’s crust, obtained through a process known as Iron Oxide Recovery (IOR). This method removes colored iron oxides that pollute mine water, cleaning the water so it can re-enter a receiving stream-and resulting in a cleaner natural environment. The recovered iron oxide is thoroughly washed, then used to create a trio of rich colors ranging in tone from a warm golden yellow to a deep red earth to a beautiful saturated dark brown with a bluish undertone.
