Dark drying oil or black oil is a fast drying oil made by heating linseed oil with lead oxide and used in historical oil painting. The lead (metal basis) content of our dark drying oil is about 3% by weight.
This is the classic drying oil made with litharge (lead oxide). Since earliest times, litharge was cooked with vegetable oil, such as linseed or walnut oil, to clarify it while removing impurities and imparting faster drying characteristics. Cooking the oil for long periods and at high temperatures allowed greater amounts of litharge to be dissolved in the oil while at the same time darkening the oil. Our dark drying oil is cooked at the lowest temperature possible to effect solution of the lead while making the palest drying oil possible.
Black oil can improve the handling and drying of oils and can be used in recipes to make megilp, Maroger medium and traditional oil varnishes, such as "olifa" used in icon painting.
WARNING! CONTAINS LEAD. Lead can present health hazards if handled improperly. Do not eat or smoke while using this product and without washing hands. Keep out of reach of children.
