Makes Gum Arabic solution. Add to watercolours to increase transparency. Binder in watercolours and gouache.
Dissolved in warm water, ratios are as follows: - Dissolve 1 part gum in 3 parts water (by weight). - For a lower viscous solution 1 part gum in 5 parts water. - For a higher viscous solution 1 part gum in 2 parts water.
Ratios may be experimented with to get solutions with different viscousities. (This affecting thickness / tackiness).
