Badania obrazu Jana Lievensa „Portret młodzieńca”

In order to determine in detail the structure of the painting, physical and chemical analyses were carried out, such as: UV light examination, IR light examination, X-ray, chemical analysis of the ground layer and pigments (of the original paint layer as well as the overpaint layers). The stratigraphy of the existing layers was determined based on the examination of the cross-sections. Pigments were identified by the analysis of their elemental contents. Chemical analyses were carried out using noninvasive methods. Measurements were carried out using X-ray fluorescence spectroscopy (XRF).
