Abstract The bronze mou was an important artifact commonly used in the Ba-Shu region (now Chongqing and Sichuan Province) during Spring Autumn Period Han Dynasty. Although extensive archaeological study of has been conducted, scientific analysis limited, no organic residue performed on mou. In this study, four mous dated to dynasty (206 BC–220 AD) with residues unearthed three sites Wushan, Chongqing, were selected for by portable X-ray fluorescent spectrometer (P-XRF) liquid...
Abstract Six iron sword samples dated to the Western Han Xinmang period (206 BC–24 AD) of Dynasty excavated from Tuchengpo Cemetery in Wushan, Chongqing, were characterized by Raman spectroscopy combined with SEM-EDS technology. The results showed that corrosion products on swords mainly divided into two layers. In external layer, mineralized wood residue scabbard was observed, and calcite, goethite, lepidocrocite, hematite, carbon detected. Different dense distinguished color, including...
<title>Abstract</title> The round lacquer lian of fabric core excavated from the Fengpengling site (Hunan, China) as one typical lacquerwares with gold and silver decoration was analyzed by digital microscopy, Raman spectroscopy, SEM-EDS, Py-GC/MS to obtain detailed information manufacturing process. results revealed six layers in sample, carbon black found on piece, sulfide cinnabar red layer. It can be inferred that animal bones were used filling material ash quartz detection...
An artifact of brass apparently predating the "Bronze Age" was unearthed at Jiangzhai site (China, Shaanxi Province, 4700-4000 BC). So that we might infer probable metallurgical process for production this early brass, performed simulation experiments that, in turn, involved two widely differing methodologies. For convenience refer to their routes as "melting" on one hand, and "solid-state reduction" other. Clearly, either these processes could have supplied starting material subsequent...
Corrosion products on three bronze swords found in tombs dating from the Warring States period at Lijiaba site, Yunyang county, Chongqing were characterized by Raman and X-ray fluorescence spectroscopies. The major corrosion cuprite, malachite, cerussite cassiterite, along with copper lead phosphates, libethenite pyromorphite. presence of pyromorphite which have been reported infrequently attributed to pH, humidity phosphorus released decomposition adjacent bodies burial environment.
Abstract The “ Tian Di Chang Chun ” horizontal plaque inscribed by the general Feng Yü-hsiang in R.O.C. 25 (1936) shows his patriotic, compassionate, fair, and just thoughts ideals. It has significant educational value for contemporary society. However, due to aging of materials some factors preservation environment, coloured decorative coating on surface shed. digital microscope system, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD)...
<title>Abstract</title> Six iron sword samples of the Han Dynasty (206 BC–220 AD) excavated from Tuchengpo Cemetery in Wushan, Chongqing, were characterized by Raman spectroscopy combined with SEM-EDS technology. The results showed that corrosion products on swords mainly divided into two layers. Shells weeping observed, and goethite, lepidocrocite, akaganeite, calcite detected external layer. Different dense distinguished color, including goethite (orange), lepidocrocite (reddish-brown),...
The “Tian Di Chang Chun” horizontal plaque was inscribed by General Feng Yü-hsiang in R.O.C. 25 (1936). Due to the aging of materials and some factors preservation environment, red painted layer on surface has shed. In this study, order analyse techniques used for production plaques, digital microscope system, scanning electron microscopy–energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), micro-Fourier transform infrared (μ-FTIR) were plaque. It been shown that decorative...
