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.
