“…Different results of the Micro-Raman spectroscopy were obtained at two detection points of red Sample JYS-2-3. At one of the points we have detected the strong Raman peaks at 252,286,342 cm -1 which correspond well to characteristic Raman bands of cinnabar (HgS) [20][21][22] . Moreover, the strong Raman peaks at 160,225,313,475,546cm -1 are assigned to minium (Pb 3 O 4 ).…”

The painted statues of Tutang Buddha and two attendants Buddha in Jingyin Temple, with exquisite design and unique style, are precious cultural heritages of China. The statue of Tutang Buddha which was carved from a mound and painted by ancient craftsmen, is rarely found in ancient China. However, on account of the influence of natural factors and artificial harms, the statues were severly damaged. Obviously, it requires urgently carrying out appropriate protection and restoration of the statues. In this study, the samples taken from the statues were analysed by multiple analytical techniques, including scanning electron microscopy with energy dispersive spectrometry (SEM-EDS), Raman spectroscopy, X-ray diffraction (XRD), biological microscopy and particle size analysis. The analysis enabled us to infer the techniques used by the creators in making the statues. This research provides reliable evidence for the conservation and future protection of these and similar statues.

With exquisite design and unique style, the painted sculptures of Tutang Buddha and two attendants Buddha in Jingyin Temple are precious cultural heritages of China. The sculpture of Tutang Buddha, which was carved from a mound and painted by ancient craftsmen, was rarely found in ancient China. However, due to natural and human factors, the sculptures were severely damaged. Obviously, they require urgent and appropriate protection and restoration. In this study, samples taken from the sculptures were analysed through multiple analytical techniques, including scanning electron microscopy with energy dispersive spectrometry (SEM–EDS), Raman spectroscopy, X-ray diffraction (XRD), optical microscopy (OM) and granulometry. The analysis results enable us to infer the techniques used by the craftsmen in making the sculptures and provide a reliable evidence for the conservation and future protection of these and similar sculptures.

“…However, the colors observed by our naked eyes or instruments such as hyperspectral cameras are usually a mixture of several kinds of pigments due to pigment usage and painting skills. Liu et al [1] illustrated that such pigments mixture were well-distributed and tight by performing three-dimension microscope analysis. Therefore, it is difficult to determine the type and proportion of the pigments on the surface of Chinese paintings before restoration.…”

Background: Mixed pigment analysis is an important and complex subject in preserving and restoring Chinese paintings since the colors observed by our naked eyes or instruments such as hyperspectral cameras are usually a mixture of several kinds of pigments. The purpose of this study was to explore a more effective method to confirm the type of every pure pigment and their proportion in pigment mixtures on the surface of paintings. Methods: Two endmember extraction algorithms were adopted to identify the types of pigments and an improved method of ratio spectra derivative spectrophotometry was used to determine their proportion. Main works: (1) Extracting the pure pigment components from mixed spectrum by adopting two blind source separation algorithms: Independent Component Analysis and Non-negative Matrix Factorization; (2) matching the separated pure spectrum with the pigment spectral library built in our laboratory to determine the pigment type; and (3) calculating the proportions of mixed pigments using the Ratio Spectra Derivative Spectrophotometry based on Mode, which is improved based on the original algorithm. Finally, a comparison was made with two abundance inversion algorithms: Least Squares Algorithm and Minimum Volume Simplex Analysis. The correlation coefficient and root mean square error were used to provide evidence for accuracy evaluation. Conclusions: (1) Non-negative matrix factorization is more suitable for endmember extraction; and (2) Ratio spectra derivative spectrophotometry based on mode is more suitable for abundance inversion.
