Gum Arabic Powder
Gum arabic is the basis of the best watercolors. It can be used to create interesting textural effects when mixed with watercolor washes. Useful in making emulsions with egg tempera and resins.
Prepared Gum Arabic Recipe
300 grams (10.5 oz) Gum Arabic powder
3 drops Clove Oil (optional)
1 liter (2.1 pints) of distilled water
The ratio is 1 part gum to 2 parts water. Boil water (or use distilled water) and allow to cool to about 140° F (60° C) and then add the powdered gum, stirring to make sure there are no lumps. Continue warming the mixture at that temperature and stirring to dissolve the gum arabic completely.
Add drops of Clove Oil to extend shelflife. Prepared Gum Arabic must be stored in the refrigerator to deter mold growth. It may be advisable to make small batches so the solution will be fresh rather than storing larger quantities for an extended period of time.
