Reef, 3 x 5 in, Watercolor and Litho gum on glazed white cardboard.

The gum solution is used in lithography to coat aluminum printing plates in order to prevent oxidation after development. The gum is traditionally Gum Arabic but is now only about 5% real gum with the balance being synthetic starches and mysterious chemicals. Mixed with watercolors; the gum makes the paint more viscous and changes the way it blends and scoots around on the cardboard.
