The method comprises the identification of oils in dried-up oil films. The following four oils used as binding agents in painting were studied: linseed oil, poppy-seed oil, nut oil and oil made from the egg yolks. The method is based on a different relation between palmitine acid and stearic acid in the above-listed oils. A separation of isolated saturated fatty acids was carried out by means o f paper chromatography. The quantitative interpretation of chromatograms was made after a densitometric method. The method was successfully employed to identify oils in samples taken from polychromed historic works of art. The samples were 10—30 mg in size.
