Tytuvėnų Švč. Mergelės Marijos bažnyčios XVIII a. dailininko paveikslo "Švč. Mergelė Marija su Vaikeliu" tyrimai
ENThe painting before restoration underwent complete chemical, physical and microbiological examination with the purpose of establishing a suitable restoration method. As the painting underwent physical examination, it was examined with infrared, ultraviolet techniques, and X-radiographs. As the object was X-rayed, looses of a paint layer, composition details, background contour relief ornaments and remaining nails in the wood base were all easily observed. In the ultraviolet photograph of the painting, dark stains were detected which denoted recent over paintings. These were found on the faces and hands of Mary and the Child as well as in the vicinity of the neck and feet of the Child. The infrared photograph revealed original drawing found underneath the layer of paint. The examination was conducted by the restoration technologist Rapolas Vedrickas. A number of samples taken from the painting underwent chemical and strati- graphical analysis. A part of samples were used for a histochemical analysis.The painting technique was determined: pigments and binders of the paint layer, ground and under painting were identified. Analysis was conducted by the expert technologist Dr. Dalia Panavaitė. Morphological analysis on the painting’s background fabric, thin-layer chromatographic analysis of the dyes, and a micro chemical and morphological analysis on the glue and paper found on the back of the wooden base of the painting were all conducted as well. This analysis was conducted by the restoration technologist Jurga Bagdzevičienė. The metal alloy samples were analysed by atomic absorption spectral analysis by Dr. Marija Jakubėnienė. At the time of microbiological testing, it was determined that the painting was contaminated by micro-fungal spores. 8 Chlodosporium Herbarum Pers colonies were actually detected as well as Penicillium sp and Penicillium oxalicum Thom. Analysis was conducted by microbiologist Irena Bubinienė. [From the publication]
