This special blend of linseed oil should only be used with water-soluble oils. If you use regular linseed oil with water-soluble colours, it makes them not watersoluble any more. This medium will add gloss to the paint film.
Holbein Duo-Aqua Oil is an artist quality water-mixable oil paint made with watersoluble linseed oil. It has all of the handling characteristics of traditional oil paints, but can be thinned or cleaned up with just water. These paints have a uniform drying time, retain brushmarks for rich painterly textures, and dry to a lustrous sheen just like traditional oils. Duo-Aqua is available in over 80 colours, 75 of which offer optimum permanence. These colours are free of pigments derived from heavy metals.
