|  DANIEL SMITH Enviro-Friendly Watercolours-the colours aren't green,  but the process is! To make these paints, we use pigments from the  earth's crust, obtained through a process known as Iron Oxide Recovery  (IOR). This method removes coloured 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 colours ranging in tone from  a warm golden yellow to a deep red earth to a beautiful saturated dark  brown with a bluish undertone. | ASTM Lightfastness Rating: Excellent Transparency: Semi-Transparent Staining: Non-Staining Granulating: Yes(PBr 6) |
