Abstract
Physical and chemical methods of analysis are indispensable for restoration, study of painting techniques, examination and attribution of works of art. Development of new directions of investigations as well as improvements in sample preparation allow applying non-destructive analysis methods, minimizing amount of matter used to obtain informative spectra, preventing alteration and destruction of samples in the course of investigation. This paper observes the examples of applying optical and spectral methods, including molecular spectral analysis and electron microscopy, for study of binding media and pigments of painting and archaeological artifacts.

Preservation of cultural heritage, study and evaluation of their condition are the main purposes of restoration and research
Indian yellow was used in Europe from late XVIII century till 1908 when its production was restricted [2]; it corresponds to period of the artist’ life
SEM-EDX method confirmed lead presence in crystals and determined their size, and XRD showed that these crystals are composed of hydrocerussite (2PbCO3·Pb(OH)2)
Summary
Preservation of cultural heritage, study and evaluation of their condition are the main purposes of restoration and research. The first stage of research involves non-sampling methods, for example, XRF and reflectance spectroscopy – which in some cases are the only possible way to examine works of art such as paper, fabrics, aquarelles and manuscripts. These methods provide the information regarding just the superficial layer. Indian yellow was used in Europe from late XVIII century till 1908 when its production was restricted [2]; it corresponds to period of the artist’ life.
