Winsor & Newton's Ox Gall Liquid is a pale, odorless liquid that increases the wetting and flow of watercolors. When mixed with colors, it can help create beautiful fluid washes on a painting's surface. This medium is also well suited for marbling with watercolors. As a wetting agent, the medium combines with the paint to help the colors float on the marbling size's surface rather than sink to the bottom of the tray.
Available in a 75ml (2.54 oz.) bottle.
