• Winsor & Newton Drying Oils are made with the same vegetable oils used to formulate the oil colours, namely, linseed, safflower & poppy. • Drying Oils are used to modify the consistency & drying time of oil paints in much the same way as prepared mediums. • The different processing methods of these oils results in a range of drying rates, consistencies & colours. • Winsor & Newton Refined Linseed Oil is their most popular oil. • It is a low viscosity alkali refined oil of pale colour that dries slowly. • Refined Linseed Oil reduces the consistency of oil colours. • It is more fluid than unrefined oils & helps increase gloss, transparency & flow of colours. • Refined Linseed oil slows the drying of oil colours and is slower-drying than cold pressed Linseed. • ART.NO. 3021748 Winsor & Newton (also abbreviated W&N) is an English manufacturing company based in London that produces a wide variety of fine art products, including acrylics, oils, watercolour, gouache, brushes, canvases, papers, inks, graphite and coloured pencils, markers, and charcoals. The standards of quality for W&N's most renowned line of kolinsky sable brush, the Series 7, began after Queen Victoria ordered it should be "the very finest watercolour brush" in 1866. A few months before his death, Henry Newton sold the business to the newly incorporated firm of "Winsor & Newton Ltd.", which included members of both families amongst the shareholders. In 1937, W&N introduced its gouache paints.
