The Renaissance stove in the Court of Arthur in Gdańsk is one of the few objects of this type which, apart from the traditional glazing, contain fragments embellished with organic paint. Orginally, the polychromy covered the stone socle of the stove, the clay frames surrounding the tiles and partially the ceramic tablet with the coat of arms of Gdańsk. The article discusses the history of research into the scheme of the stove as well as the outcome of laboratory examinations into the races of the extant original layer and numerous repainting. The table displays the composition of paint used for particular fragments of the stove. The colour boards interpret the outcome of the research and show the appearance of the original design and subsequent repainting. The results of the study have been confirmed after the reconstruction of the solid of the stove which comprises a consistent architectonic and painting composition. The polychromy of the corner tiles and frieze emphasises its architecture. Elements of the crown and base echo the multihued tiles. The gilt fragments, endow this enormous construction with a certain feeling of lightness.

The first part of the paper presents a brief characteristics of both the employed research methods and the mode of interpretation of the results obtained in the polarogram. In the following parts, the general schemes are given o f the examination of yellow foils (the gold one and ’’goldmetal”), the white foils (silver, aluminium, tin) and, also, the detailed methods o f the analysis of the respective foils. All the foils mentioned above were subject to a qualitative examination basing on model samples. The quantitative composition was ascertained but with regard to the so-called gold-metal foil, a standard alloy of known composition, two different gold-metal foils, and the gold-metal foil sample — taken from the historical object — having been used for the purpose. The results of the quantitative analysis carried out were calculated according to the scheme given in the Table. Now in the part dealing with research on the foil from the historical objects the mode of taking samples, and their preparation for polarographic analysis, are described. The assay o f the samples was conducted in strict consonance with the description given in the experimental part of the paper. The results obtained in investigation of the foil taken from historical objects were identical with those of the analysis of model samples. Polarography is thus a method which may be successfully applied in the examination o f gold-foil.

A tile stove from the Arthus’ Court, built in 1545— 1546, is the most valuable example of the Pomeranian ceramics. In 1943— 1944 free-standing part of the stove was dismantled. The tiles were transferred to a cloister in Kartuzy. They were uncovered in 1945. The tiles and non-disassembled part of the stove were preserved with the reconstruction of the stove in mind. In 1983 conservation work was initiated with the aim to reconstruct the stove. At the same time conservation, technological and documentation work was carried out. The analysis of the colouring of the stove was one of the stages of research work. Physical and chemical examinations covered polychromy of a stone plinth, clay listels constituting the framing of the tiles and an alabaster panel placed at its moulding. Detailed results of the studies made by the author are presented in this article. Results of the studies as well as information contained in literature on the colouring of the stove made a colour reconstruction of the object much easier. Moreover, the obtained research material may be employed in the analysis of polychromy of other stone and ceramic objects of that period.

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.
