Gum Arabic – Natural Binder for Art

Gum Arabic is a natural gum obtained from the trunks of acacia trees. It is also known as acacia gum or Senegal gum. Since it is edible, it is used not only in art but also in the food industry as a regulator. Due to its water-soluble properties, it is commonly used as a binder in watercolor painting. Throughout history, painters have used this resin to bind their colors and enhance their gloss.

Uses of Gum Arabic

One of the most important features of Gum Arabic is that it is non-toxic. In the desert regions of Sudan, some tribes have survived by consuming this substance obtained from acacia trees. Because it is natural and non-toxic, it is ideal for use in the art field.

In medieval painting, Gum Arabic was used in tempera painting techniques and gold leaf decoration. In ceramic art, it is used as a glazing aid before firing the ceramics in the kiln.

Purpose and Application of Gum Arabic

Gum Arabic is often sold separately as an auxiliary material and is used to increase the gloss and adhesion of watercolor paints. It is generally mixed in a ratio of 1 part Gum Arabic, 2 parts water, and 1 part paint. Some artists prefer to add Gum Arabic to the water in which they mix their paint rather than directly into the paint. It also increases the density and consistency of the watercolor, helping it dissolve better in water.

In high-quality watercolor paints, there is usually enough Gum Arabic, so additional additives may not be necessary. However, excessive amounts of Gum Arabic can cause unnecessary gloss and lead to cracks when the paint dries.

Gum Arabic is a versatile material and is also widely used in marbling art (Ebru).
