The object of the Project is the retrieval of the Lost Technologies for the production of materials and cultural heritage objects, in particular glasses, glazed ceramics and paintings, to gain knowledge and improve the conservation of the materials. This study is necessarily multidisciplinary, but also cross-disciplinary because to the scholar documental and archaeological survey we must add the analysis of the objects. Considering the transversal character of the study, the group is cross-disciplinary: historians, archaeologists, conservators, curators and scientists of different areas physics, chemistry and geology- collaborate configuring a work team. Consequently, this Project has direct incidence in the retrieval of our, both tangible and intangible, Cultural Heritage. The study of painting layers, glazed and decorated ceramics and enamels possess common specific problems from the analytical point of view: the layers are very thin, from microns to some tens of microns and constituted by many compounds. The layers normally have a vitreous matrix, containing metallic ions and also micro- and nano-particles to give colour and opacity, and also other compounds which result from the reactivity and alteration of the layers. Our research group has a wide experience in the development of optimal methods for the preparation of samples, use of microscopic and micro-spectroscopic analytical technics (MO, FE-SEM-EDS, LA-ICP-MS, UV-Vis-NIR, IR, Raman), as well as, of new non-destructive micro-analytical techniques using large synchrotron light facilities (μ-XRD, EXAFS, μ-IR, μ-XRF). One of the novelties of our proposal is the validation of the processes followed in the production of the historical materials by their replication. The group has a set of equipment for the analysis, preparation and replication (kilns, and chemical synthesis) either in our premises or other geographically close institutions. Our group has also a wide experience in the use of large facilities (synchrotron light, ion beams). Selection of the materials with scientific, historical and conservation based criteria is one of the fundamental ground stones of our work plan, and essential for obtaining relevant data. Our group collaborates with Museums and Research Centres in Archaeology and Conservation that guarantee the access to material for the development of the Project. The project is focused in four specific research lines: - Technique, use and alteration of the lead compounds in paintings from Roman to Barroc. - Processing of raw materials for the production of historical glazes and pigments - Technology transfer in the tin glazed ceramics in the western Mediterranean during the Medieval Ages. - Study of the materials, production technology and conservation of enamels in porcelain and stain glass.
