%X (FT) Raman spectroscopy is used for the first time to identify pigments used in 19 th & 20 th century Japanese and Vietnamese Lacquerwares. IR spectroscopy is used to assess the Lacquer matrix. Different operative conditions and parameters were experimented with on a limited number of lacquerwares in order to determine the optimal procedure for the identification of pigments/dyes as potential chronological or technological markers. The test was then performed in the collector¡¯s rooms with a mobile Raman set-up. Different pigments (vermilion, Prussian Blue, Naples Yellow, Phtalocyanine Blue, anatase, rutile, chalk, carbon black) were identified despite a strong fluorescence and a rapid degradation of both pigments and binder under increasing laser power. Better spectra were obtained on older lacquerwares.
