Oil extracted from poppy seeds, one of the most popular of the drying oils used as a medium for oil painting. It is less viscous than linseed and walnut oil and does not easily turn rancid. It is, however, slow drying. This turned out to be an advantage rather than a disadvantage when alla prima painting came into vogue about the middle of the 19th century and for a time during the second half of that century poppy oil was much used by commercial colourmen.
