THE USE OF THE LATEST CONSERVATION TESTS IN THE DETERMINATION OF THE TECHNOLOGY AND STATE OF PRESERVATION OF THE PAINTING BIAŁA DAMA [WHITE LADY] – A PORTRAIT OF TEOFILA NEE DZIAŁYŃSKA, SZOŁDRSKA BY HER FIRST MARRIAGE, POTULICKA BY HER SECOND MARRIAG

Summary/Abstract: The article presents results of examinations of the technology and technique of the creation of an 18th-century painting kept in the collections of the Castle in Kórnik. Th e structure of the painting was examined for the very fi rst time using a combination of non-invasive and micro-invasive techniques, including non-destructive imaging techniques such as roentgenography (X-ray), ultraviolet refl ectography (UVR), ultraviolet fl uorescence (UVF), visible refl ectography (VIS), infrared refl ectography (IR), as well as techniques of imaging using false colour: ultraviolet (UVFC) and infrared (IRFC). Th e chemical composition of the painting layers was checked with the help of microchemical and instrumental methods: X-ray fl uorescence (XRF), infrared spectroscopy (FTIR), electron microscopy (SEM-EDS) and gas chromatography (GC). Th e tests were aimed at the identifi cation of the pigments and binders used by the artist and determination of the state of preservation of the work.
