Component analysis of pigments is very important in terms of forensic art or restoration of artworks and cultural properties. In this study, the components were analyzed by non-destructive analysis methods such as spectrophotometry, X-ray fluorescence(XRF) spectroscopy, X-ray diffraction(XRD) spectroscopy and Raman spectroscopy for 37 types of natural pigments(Natural Seokchae). The analysis found that there were some color differences depending on the type of main coloring mineral, the degree of other mineral content and the stoichiometric compositions. As a result, the constituent elements of the Natural Seokchae were determined by XRF. The coloring minerals such as azurite and lazurite(blue), malachite and celadonite(green), cinnabar and realgar(red), orpiment(yellow), goethite and hematite(brown), calcite(white), ilmenite(black), and clinochlore(gray) were determined by XRD. Raman spectra were obtained from 30 out of 37 samples; specific peaks of azurite, lazurite, malachite, cinnabar, realgar, calcite, albite, quartz and goethite were identified according to their corresponding pigments.
