Winsor & Newton
Winsor & Newton Gum Arabic is to watercolors what linseed oil is to oil paints. Most watercolors use Gum Arabic as part of the binder for the color. Adding Gum Arabic to a tubed watercolor will increase the transparency and add slight glossiness to the color. Gum Arabic solution is thickened to closely emulate the consistency of the paint from the tube. 75 ml bottle.
