Non-invasive Analyses of Ancient Ceramics Colorants
نویسندگان
چکیده
Present research exploits the benefits of the non-invasive and non-destructive spectroscopic methods in order to characterize the pigments which constitute the colorants found on ancient ceramic pieces. A red colorant, which occurs on the outer surfaces of the ceramic pieces excavated from archaeological finding sites Čepin-Ovčara and Kneževi Vinogradi-Osnovna škola and in earth piece from AljmašPodunavlje locality was analyzed. Using the UV-Vis FORS and Raman spectroscopy, red colorant is found to be red ochre. Raman spectrum of red ceramic colorant agrees with the spectrum of the colorant from the earth piece, leading to the conclusion that the Neolithic culture living in today Slavonija and Baranja region used the same colorants for decorating their ceramics as other nearby Neolithic cultures of Pannonian Basin. Black colorations are found to be made of soot.

Non-destructive tests (NDT) of historical artifacts are the ideal scientific tools for the analyses of culturally important heritage objects. However, for the investigations of certain materials, especially natural organic dyes and pigments, it is important for curators, conservators, and scientists to be aware that such analyses are not always practical or prudent. At best, NDT can definitivel...

Non-destructive analysis of cultural objects by micro-XRF spectrometry is an advantageous multi-element technique that has rapidly developed during the past few years. Portable instruments contribute significantly to the in situ analysis of valuable cultural objects, which cannot be transported to the laboratory. Ancient ceramics are the most common archaeological findings and they carry a sign...
