Also known as Gum Acacia, this item is the traditional binding agent used in watercolour paints. The gum is extracted from two types of Acacia tree and is non-toxic. It can be added to further increase the viscosity helping to prevent spread and can be used as a binder medium, emulsifier and film former in a variety of ways. When combined with Pearl Ex or other pigments, it will produce a glossy, brushing or stamping solution and is easily mixed and cleaned up with water. Mix with 4 parts Pearl Ex to one part Gum Arabic and water to make watercolour paints or calligraphy ink.
Prepared solutions can be stored for convenience.
