摘要

This paper presents a physico - chemical study of the paint layers of "Saint Nicholas" icon, which comes from a private collection in Romania. The icon has artistic characteristics of the Russian icons, the Post-Byzantine style, and is an expression of the painted art in the Orthodox Church. Significant information about the icon painting technique, the materials used and about the period in which the icon was made, were found using new analytical techniques. The aim of this study is to gather useful information about the icon to make a suitable conservation and restoration treatment of the artifact. For the analysis of the icon's materials (preparation layer, paint layer and varnish), Optical Microscopy (OM), scanning electron microscopy connected with X-ray spectrometry (SEM-EDX) and Fourier transformed infrared spectrophotometry (mu-FTIR), were used. It was concluded that the paint layer is made of tempera (pigment with egg-based emulsion), painted over silver leaf, over which olifa varnish was used. Based on the style of the painting and on its conservation state, it is presumed that it was painted in the XIXth century. The corroboration between the analytic data, highlighted different details of the painting process and of the used materials. Thus, mineral pigments, colored earths, silver leaf and paper stripes under the gesso were identified.
