DANIEL SMITH Extra Fine™ Enviro-Friendly Yellow Iron Oxide Watercolor 15 ml. - World`s finest artists` paints

Our Enviro-Friendly Yellow Iron Oxide is a deep, rich ochre. DANIEL SMITH Enviro-Friendly Watercolors-the colors 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 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. Starting with 10 parts water to 1 part paint (by weight) in the palette, our chemist paints the top half of the swatch uniformly with a round brush to show the paint’s color and characteristics. For the bottom half, he dips a ¾” flat brush into the paint well just once, then applies the color in stripes until the brush is dry, which shows the color’s tone and behavior through a wash. We use these swatches for color matching during the manufacturing process.
