Abstract

We discuss here materials used in the fabrication of works of art and handicrafts, among them pigments and dyes, gemstones and jewels. Attention is paid to their natural or synthetic origin and possible treatments. Methods of characterization are important not only for historical and restoration purposes and the reproduction of ancient processes, but also for the purposes of new productions. In particular, in the fields of the Effective Microorganisms and metal surfaces coloration, some goals have been reached in this direction due to convergence of different education and research experience of the authors.
