Winsor and Newton Artisan Water Mixable Oil 37ml - Ivory Black (Series 1) (WNO331) Artisan Water Mixable Oil Colour is a genuine oil colour made from modified linseed oil and modified sunflower oil. It has been specifically developed to appear and work just like conventional oil colour. The depth of colour, buttery consistency, lightfastness, opacity/transparency, performance and drying times of Artisan allow artists to use this range for all oil colour techniques. The key difference between Artisan Water Mixable Oil Colour and conventional oils is their additional ability to mix with water. After painting, brushes can be cleaned using only soap and water. Artisan is popular with oil painters who do not like the smell of turpentine or wish to cut down or eliminate the use of traditional solvents. As a result of avoiding such solvents, painting with Artisan is less hazardous, which can be particularly useful in art schools or enclosed spaces. A range of unique Artisan Water Mixable Mediums has also been developed to allow the full range of traditional oil colour techniques and styles to be achieved.
