Schmincke Horadam Aquarell Onetz Oxgall Medium

Schmincke Horadam Onetz Watercolour Medium can be used to modify the working characteristics of your watercolour paints. Onetz is a natural, thickened Oxgall wetting agent, designed to improve the flow of your watercolour or gouache colours. It will decrease the surface tension of your colours when diluted with water. A little of this medium goes a long way, so it should be used sparingly.

Available in a 5ml or 15ml tube

• Onetz Oxgall is fully water-mixable
• Dilute the medium with a little water and then separately mix into your watercolour paint on a palette. Use only a little of the medium.
• Make sure to clean the tools you have used with this medium with soap and water once you have finished using them
• Dissolved Oxgall can flocculate when it has been left in storage for a long period of time, but it should not effect the handling of this product.
• Onetz can also be used to 'degrease' undercoats such as lacquered palettes of painting boxes.
• Secure the lid of the tube tightly after use.
• Store in a cool, dry place.
• It is always advisable to test a small area with this medium before you use it on your final work.
