Characterization of mineral pigments used in traditional Japanese paintings

Abstract

Artworks have been subjects of many researches during the recent years due to the technical challenges they present. In this study, characterization of mineral pigments used in traditional Japanese paintings was explored. The techniques were categorized as either x-ray-based or visible light-near infrared-based. The techniques used were a combination of spectroscopy and imaging. Results of the experiment revealed insights on the elemental composition and structure of the pigments, degradation and discoloration mechanism and the time-dependent changes in the reflectance and absorption of the pigments subjected to extreme conditions. All of which are important in understanding cultural heritage for the purpose of restoration, preservation and conservation.
