Our Linseed Oil is unique. It starts with unrefined flax oil purchased directly from a family-owned farm right here in Canada. This oil is slowly extracted from premium, certified-organic seeds on a dedicated mechanical expeller without the use of heat or solvents.
We use a slow and gentle process called the "CSO Psyllium Husk-Alcohol Method" to cleanse the oil of impurities. This process was created by Mr. Louis R. Velasquez and was inspired by the methods of 17th Century Spanish Artist and Teacher, Francisco Pacheco, as recorded in his book "Arte de la Pintura".

Our Thickened Linseed Oils are naturally fast drying because they are pre-polymerized (and oxidized) as a result of exposure to light, heat, and oxygen. Therefore, they require no addition of solvents or metallic driers to speed up drying time!
