Winsor & Newton Drying Linseed Oil is darker than refined Linseed Oil, this oil promotes the fastest drying rate of all the oils, whilst increasing gloss.
I mix drying linseed oil (@ 40%) with terpentine and my oil paints dry over night - best drying mix I have used so far. Christer Hägg (Stockholm, Sweden) on 24 Aug 2012
I use this oil to speed up drying time of oil paint. If drying time of oil paint is important then this is a good product. Susan Khushi (Wakefield, United Kingdom) on 3 Jul 2012
only used once it does speed drying and it does add gloss Nancy Moroney (Stewarton, United Kingdom) on 14 Sep 2012
