Oxgall is used to improve flow of watercolors. Natural wetting agent for watercolors and gouache colors. Decreases the surface tension of the colors diluted with water. Use sparingly. 

• Shake well before use.
• Oxgall is water-mixable.
• Dilute the product with a little water and mix it into the water-colours separately on a palette. (Use sparingly!).
• Please clean working tools as soon as possible with water or water and soap.
• Dissolved oxgall tends to flocculate during a long period of storage; this has no influence on the product`s handling.
• The product also “degreases” undercoats such as lacquered palettes of painting boxes.
• Close immediately after use.
• Store in a cool and dry place.
• Individual pre-tests are required.
