Gum Arabic is a resoluble binding agent, commonly used in the preparation of watercolours, 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 watercolour painting, while Nigerian Gum Arabic (while stocks last) is better suited to stone lithography and other printmaking techniques. Please see the Formulas & Recipes section on our homepage for a recipe to make your own watercolour paints using Gum Arabic (currently under construction). Learn More

Cobalt Blue is an artificial mineral pigment, produced by the calcination of cobalt oxide and aluminium oxide. It has been widely used since the early 1800s, following its discovery by the French chemist Thenard at the beginning of the century. The name Cobalt has its roots in the German word Kobold, meaning imp or evil spirit. German miners specifically used this name in the late-Middle Ages, as the presence of Cobalt ore in the mines made the extraction of silver very difficult. They were possibly aware of the toxic properties of the mineral frustrating their efforts.

Cobalt remains a very popular colour today, and is present in most ranges of paints, being a semi-transparent pigment that is stable in all media. As a watercolour, all cobalt pigments tend to granulate. As an oil paint, it requires less oil content than most other pigments, and dries quite quickly. Like Cerulean Blue, some artists may choose to bind it with poppy oil, to avoid any possible colour changes brought about by the yellowish cast of linseed oil and the pigment's weak tinting strength.
