Summary/Abstract: Art is a specific human activity that aims at producing aesthetic values and using specific means of expression. Moreover, arts are distinguished by the material used (painting - color, sculpture – stone or wood, literature – words, music – sound or note), but they share the artistic image underlying the act of creation. Authentic - False in artworks should not only focus on the substrate, the paints, the background, the lacquer, but also on the technique used to verify that it corresponds to that of the painter. The resolution of these problems cannot be conceived without the use of laboratory techniques that reflect a predominant place in the observations of the person skilled in the art. Therefore, the identification of technical investigations should be carried out systematically for each expertise. These expertises can be simple, convenient and efficient. In this paper is presented an overview of trace evidence and chemical painting techniques used in artwork and the applicability of chromatography, spectroscopy, X-ray radiography, neutron autoradiography and conoscopic holography as a tool for investigations of the material composition of the paintings. X-ray radiography and neutron autoradiography, for example, are nondestructive techniques which enable determination the structure of the components and also the material composition. The applications of these techniques answer the questions when, where, or by whom such a painting was made.
