ARCHAEOMETRIC APPROACH ON THE STUDIES OF CULTURAL HERITAGE OBJECTS

The scientific studies, which are carried out on the cultural heritage items, identify the provenance and authenticity of the studied artifacts as well as shedding some light on the technology of production period. Besides, the studies lead to choosing both the appropriate materials and techniques for the restoration and conservation treatments. Nowadays, non-destructive models of some destructive techniques (Raman spectroscopy, X-rays fluorescence spectroscopy) by on-site measurements, due to it renders to possible, increased studying the number of archaeometric works on the cultural heritage artifacts, in the excavation sites, museums, and private collections. In this study, I analysed two porcelain plates of Limoges production with a portable X-rays fluorescence (p-XRF) instrument revealing the compositional differences between the yellow coloured places are intact and renovated adornments. The restorator was able to obtain a very similar hued yellow colour by a very different composition from the original decor. Notwithstanding, visually, light and dark shade differences are apparent. Material analysis to be performed before renovation ensure the restoration to be aesthetically and physically permanent and sustaine
