Liquid gum arabic is a natural binder commonly used in calligraphy and watercolor painting. In calligraphy, it helps improve ink flow and adhesion, making strokes smoother and preventing ink from feathering or bleeding on paper. It can also slightly slow the drying time, giving you more control while writing. In watercolor, it enhances color brilliance, transparency, and adhesion to the paper, while also helping to prevent cracking as the paint dries.
