Poppyseed oil dries much more slowly (5–7 days) than linseed oil (3–5 days). For this reason poppyseed oil should not be used for a ground layer of a painting, and linseed oil should not be painted over a layer of poppyseed oil. Poppyseed oil is the basis of lipiodol, a

From 1900 to 1911, France and Germany together produced on the order of 60,000,000 kilograms per year. At that time, poppyseed oil was used primarily to dress salads and frequently was adulterated with sesame oil and hazelnut oil to improve the taste of oil from stored (rancid) seeds. Poppyseed oil was used to adulterate
