Traditional mediums include gum-water, watercolor medium, watercolor gel, watercolor megilp, wetting agent (such as ox gall), and glycerin. Gum arabic is the binding agent in watercolor; if you add more gum arabic to paint, you will lessen the spread of color when you paint wet-in-wet.

Frequently Asked Questions
What medium do you use for watercolor?
Why is honey used in watercolors?
Honey is an ingredient in many watercolor brands. It is a humectant that helps the paint retain moisture and re-wet after drying.
What does glycerin do to watercolor?
Glycerin (also called glycerol or spelled glycerine) is a plasticizer and humectant that is added to glues and starches to make them more flexible and prevent cracking. Glycerin helps watercolor to remain wet longer on the palette.
What does gum arabic do for watercolor?
Gum arabic is the traditional binder in watercolor paint, although commercial watercolor paints contain dextrin, starch, or other gums.
What is ox gall, and how is it used with watercolors?
Ox gall is gall, usually obtained from cows, that is an ingredient in bile soap mixed with alcohol and used as a wetting agent in paper marbling and watercolors. Most preparations today named "ox gall" are synthetic surfactants or surface active agents used in watercolor as a wetting agent or dispersant to improve flow and aid in wetting your paper.
What does adding salt to watercolor do?
Salt acts as a resist. Salt pushes the watercolor paint away and thus causes a lighter spot to be surrounded by a darker shade.
