| Sumario: | Research activities in the area of archaeometry is proposed by using different analytical techniques that allow us to make a compositional and microstructural characterization of a set of archaeological samples.Archeometry is a discipline that deals with the technical study of objects considered from cultural heritage (archaeological, paleontological objects, art pieces, among others) studied by various analytical techniques. The analysis is in order to obtain more information that the object itself can not show through its simple observation. In particular, archeometalurgy focuses on the knowledge of metallurgical activity and on developing interpretations about the role and meaning of metal in society and in the economy of past communities. This field of research deals with the processes, techniques, contexts, uses and ideologies that surround the development of metallurgy through the waste of manufacturing and finished products. Metallurgy is probably one of the areas of technology that has had the greatest influence on the economic and social transformations of human societies.Thanks to the collaboration with the ?Grupo de Arqueometalurgia (GAM)? of the University of Buenos Aires, we were able to obtain a series of samples recovered from different shipwrecks. Essentially, these consist of fragments of pieces composed of copper alloys that have different oxidation states, mostly belonging to the lining of the hull of ships.In the first place, the interest of these samples is to know the elementary chemical composition, in particular, to find traces of different elements. In collaboration with the Neutron Activation Analysis (AAN) research group of the Bariloche Atomic Center, we will apply this technique in order to find light elements at low concentrations (<1,000 ppm) such as antimony (Sb) and arsenic (As) . The presence and proportion of these trace elements, would allow the evaluation of differences in composition in relation to the origin of the materials used to produce the metal-sheets. Secondly, we will apply other characterization techniques such as X-ray diffraction, optical micrographs and electronic scanning in order to provide compositional information and microstructure of materials. |
