Schmincke Oxgall is a wetting agent for watercolours and gouache colours. It improves flow on surfaces which are difficult to wet and can be used from very hard sized papers to ease surface tension. An important criterion for the highest quality is being able to control the application of watercolours without the appearance of undissolved pigments and undesired cloud formations.
The perfect flow of Horadam Aquarell watercolour is guaranteed by the optimal amount of oxgall that you use. It’s the decision of the artist - not of the colour – whether or not the application should flow in moist or if the colour should stay dry on the paper.
Oxgall improves flow and enhances wet-into-wet techniques when mixed with watercolours. It also improves the acceptance of watercolour paints on paper, particularly hard-sized papers.
It is made from entirely natural ingredients. When handling, shake well before use and dilute the Oxgall with a little water on a palette. Use sparingly as a little goes a long way! It’s easily cleaned with water and soap and is best stored in a cool, dry place.
