Made with the same vegetable oils used to formulate oil colours — namely linseed, safflower, and poppy — drying oils are used to modify the consistency and drying time of oil paints in much the same way as prepared mediums. The different methods of processing these oils result in a range of various drying rates, consistencies, and colours.

Drying Poppy Oil — The palest of all the drying oils, Poppy Oil is specially formulated for use with white and pale colours. It reduces the consistency of oil paints while increasing their gloss and transparency. It also resists yellowing and is enhanced with siccatives to increase the drying speed of this naturally slower-drying oil.
