Winsor & Newton Artisan Water Mixable Oil Paints and Mediums
These oils paints are used exactly the same way as traditional oil, but they can be cleaned up with soap and water. This makes them great for the classroom or for any situation where you want to avoid exposure to solvents. Special mediums can be used with Artisan oils so that they remain water mixable. They are just as slow drying as traditional oil paints.
