IDENTIFICATION AND DIFFERENTIATION OF OPAQUE CHINESE OVERGLAZE YELLOW ENAMELS BY RAMAN SPECTROSCOPY AND SUPPORTING TECHNIQUES*

摘要

Using Raman spectroscopy, energy-dispersive X-ray fluorescence and X-ray diffraction, the Pb–Sn–Sb triple oxide yellow and lead–tin yellow have been identified on two pieces of cloisonné enamel (Falangcai) porcelains. Lead–tin yellow and lead antimonate yellow have been identified on famille rose porcelains manufactured before and after 1911, respectively. The replacement of the Pb–Sn–Sb triple oxide yellow by lead–tin yellow and that of the lead–tin yellow by lead antimonate yellow are discussed.
