Oxgall solution from Schmincke When oxgall solution is added to Schmincke Horadam Watercolours the flow properties of the colour is increased. Ox Gall is a refined, purified extract from the bile taken from the gall bladder of an ox. This natural, historically used material is used to thin water and improve the wetting of Gum Arabic in water colour and gouache. It actually makes water “wetter”! Did you ever have a dark, hard ring form around a soft pool of colour on your painting? Ox Gall can help with that, acting to break the surface tension of water into a sheeting action that overcomes edge-ringing or staining and better wetting means improved flow of washes. Tired of trying to remove streaks from a smooth flow of water colour? Adding Ox Gall, wetting is uniform, meaning that washes flow out evenly and adhere to smooth surfaces without bubbling or streaking. Wetter, thinner water also makes washes stain more deeply into the paper. Normally, Ox Gall is used in small quantities; an average use is 3 to 4 drops per cup of water. However, Ox Gall can be added to water in any amount desired or may be used full strength; it can even be applied to paper and painted on either wet or dry. Such flexibility provides artists with a variety of ways that water colours may be made to flow and adhere to surfaces. Again, experimenting is the key to learning how to use Ox Gall. 60ml bottle 200ml bottle
