Gum Arabic is a resoluble binding agent, commonly used in the preparation of watercolors, but also useful as an adhesive, a size, and in the production of soft pastels.
It is a natural product, harvested from the Acacia tree between October and May. The highest grade of Gum Arabic comes from the Kordofan region of Sudan.
It is exceptionally pale and pure and therefore particularly suited to watercolor painting, while Nigerian Gum Arabic (while stocks last) is better suited to stone lithography and other printmaking techniques.
