IDENTIFICATION OF ANCIENT AND MODERN EUROPEAN OR ASIAN PORCELAINS BY NON-DESTRUCTIVE RAMAN SPECTROMETRY

Selected porcelains, celadons and faiences, representative of the different production technologies used in the Asian, European and Islamic worlds, were studied by non-destructive macro- and micro-Raman spectroscopy. Raman-based discrimination between soft- and hard-paste porcelains is very easy to observe. Identification of many coloured phases specific to old artefacts was performed on the basis of a reference database. The technique appears well suited for analysis of white, green, yellow, blue, brown and red colours. It is efficient in spite of the small size, low crystallinity and low amount of the probed phases. 8 refs.
