Dark Drying Oil or black oil is a fast drying oil made by heating linseed oil with lead oxide (litharge) and used in historical oil painting. The lead (metal basis) content of our dark drying oil is about 3% by weight.

Use

Black oil can improve the handling and drying of oils and can be used in recipes to make megilp, Maroger and Roberson's mediums and traditional oil varnishes, such as copal.

History

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.

Source

Dark Drying Oil is prepared by heating akali-refined linseed oil (derived from the dried ripe seeds of the flax plant [Linum usitatissimum, Linaceae]) at the lowest possible temperature (less than 180 °C [356 °F]) for several hours to dissolve litharge (lead monoxide).
