Poppy seed oil
A naturally, colorless, transparent drying oil obtained from the ripe seeds of the opium poppy (Papaver somniferum) native to the western Mediterranean region. Poppy seed oil contains the following fatty acids: linoleic (62-72%), oleic (10-30%), palmitic (9-10%), stearic (1.5-2.5%) and linolenic (0-5%) (Serpico and White 2000). Manufactured poppy seed oil comes primarily from India, Russia, France and Asia Minor. Cold pressed poppy oil is nearly colorless, but the hot pressed oil is reddish. Poppy oil dries slower than linseed oil, but it yellows less, so it was sometimes used with white pigments starting about the 17th century. It produces a soft, rubbery paint film with a long wet-in-wet work time that was popular with Impressionist painters. Thick layers of poppy oil paint films tend to wrinkle and crack on aging.
