The author gives a short story of the Japanese lacquer, describes the method of its obtaining by incising of tree trunks and that of its cleaning. Within the further parts of his report he deals with application of lacquer as the decorative coating on objects made of potter’s material, wood, textixles or metal. In 1972 the National Museum, Cracow, has applied to the author for supplying them with a method of restoration of a part of the Japanese armour coated writh black lacquer. In the course of examinations it has proved namely that the lacquer exhibits losses in some places and beneath its layer is to be found a brown-coloured deposit of iron oxides. It became evident that the iron parts have been attacked by corrosion and, as a result, their restoration was required. A decision was made to apply a newly developed product known as TRUSTAN which is being used for preventing the corrosion of iron. This composition contains a derivative of tannic acid accompanied by a considerable number of hydroxyl groups. The reconstruction of the decayed lacquer was carried out with the use of synthetic dyed with black pigments. After a series of tests applying various components a mixture of resin and wax has been selected which was obtained from the melted estrificated rubber and the raw wax. This mixture was coloured by the use of the ground carbon, soot and graphite. The dry mass was polished and the final finish was applied by means of wax.
