A specially modified linseed oil for use with Holbein DUO Water Soluble Oils, DUO Aqua Linseed Oil has all the characteristics of traditional linseed oil, but is water mixable.
This is a linseed oil that increases the transparency and gloss finish of Duo Aqua Oil Colors while slowing drying time. It can be thinned with water; the resulting milky appearance will become clear when dry. While Duo Linseed Oil may become cloudy over time, its performance is not affected.
