La plaque de duralumin 1P-A6 (ЬЭбО mm X 1400 mm), fixée sur un statif, est réchauffée par des radiateurs montés stablement sur des isolateurs sur un panneau d’amiante. Les éléments de chauffage sont repartis en deux circuits, dont l’un réchauffe la partie centrale de la table et l’autre, les rebords. Chaque circuit est commandé séparément par un système de réglage transistor muni d’éléments capteurs de résistance en cuivre contactant la partie intérieure de la plaque. Le réglage de la température se fait automatiquement de 30° à 160° С et l’écart de temperature distribuée à la surface de la table n’excéde pas + 2°C. Le chauffage de la surface de la table à 60° С demande 20 minutes et le refroidissement s’obtient à l’aide d’un ventilateur placé au-dessous du niveau de la table. Trois orifices d’extraction se trouvant dans le plateau de la table sont reliés par conducteurs passant par une valve à vide à une pompe rotative 'MP5'. La valve à vide prémunie d’un manomètre gradué de 0-1 kG/cm2, permet de maintenir la pression à un niveau donné. Les tessaux garnis de caoutchouc et maintenus par des charnières aux rebords de la table servent à la fixation d’une membrane à la surface de la table, durant l’évacuation de l’air à l’aide de la pompe.

Chemistry was introduced in the program of training conservators of works of art at the Academy of Fine Arts in Cracow in 1952, and general physics at the beginning of the 1 960's. At first, due to the lack of staff members and a laboratory — the institute made use of the help of the Mathematics-Physics-Chemistry Department and the Institute of Physics of the Jagiellonian University. Today, the Department of Conservation of Works of Art has its own staff and laboratories. The program of teaching these subjects was outlined, adapted to the needs of conservators of works of art. The equipment of the laboratories today makes it possible to conduct research on works of art in a wide range.

The spectral microanalytic method using laser has been described in the article with a particular stress put on its aspects having essential importance for examination of the objects of art. Basic procedure is being reported on an example furnished by application of the laser microanalyser, model LMA-1 manufactured by the East-German firm C. Zeiss, Jena. Critical remarks are supplied by the author with regard to advantages of the qualitative and quantitative laser analysis in comparison with other analytical methods.

The examination of samples of paint material from the composition in question was conducted with the help of different physico-chemical methods. The pigments were analysed by means of microchemical, microscopic and spectral methods. The X-ray difraction method made it possible to determine variant I of the zinc-lear yellow hue, and infra-red absorption spectphotommetry conformed the presence of azurite. The spectral emmission analysis was implemented for the whole range of colours in the Gothic mural, and it was discovered that arsenic is present in the azurite, and zinc - in the natural Earth pigments. An analysis of samples of binders was conducted with thin-layer chromatography and absorption spectophotometry. It was found that binder used was casein. Chemical methods and microscopic observation of the ground provide information about the quanntitative composition of the binder, the filler and the hydraulic additives. (translated by A. Rodzińska-Chojnowska)
