Reanalysis on the Spectral Characteristics and Materials of Jade Jue Unearthed from Lijiashan Ancient Tomb in Yunnan Province, China

Jade ware Jue is one of the most fashionable ornament in ancient China from the Neolithic Age to the Han Dynasty. In this study, the remnants of jade ware Jue, from Lijiashan ancient tomb group have been tested and analyzed respectively. The samples through a light etch surface showing glass luster and those with a severe etch surface showing earthen luster. With the aid of X-ray fluorescence Spectrometer (X-ray Fluorescence) test and X-ray diffraction (XRD) detection, the results show that tremolite is not the main mineral of the sample. The main components of the tested samples with light erosion are antigorite and talc, although the main components of the samples with severe erosion are calcite containing calcium carbonate barium. Furthermore, the research on jade ware Jue in Yunnan culture has not only contributed to our further understanding of the jade objects from Yunnan culture and the variety of jade material located in the Yunnan Province. It also provides a basis for the trace of the history and culture through the distribution and evolution of burial hierarchy laws. At the same time, the microscopic observation of the tested samples manifested a residual trace of "string" at the perforation, which has played a critical role in restoring the wearing of jade ware Jue from the tombs of the ancient Yunnan State and the handicraft skills at that time.
