The Identification Of Coiling Dragon Stamps’ Printing Materials In The Late Qing Dynasty

Imperial China coiling dragon stamps were the first set of stamps that issued after the post office opening of the Qing dynasty and had profoundly impanct on the China’s stamp printing and issued. In this paper, the history of the study is supplemented by technological analysis. Firstly, in document research, to hackle coiling dragon stamps’ and pressed stamps’ printed and issued history.A collection of stamps of association management system.Then, analysed coiling dragon stamp samples of three versions by non-destructive equipments. Samples were observed and compared by the super depth 3D video microscope and to determin the different types of samples of printing progress, whether there was gum, the size of the perforations, whether the printing material had a watermark and other information. Taking advantage of micro confocal Raman spectrometer analysed that the samples were printed by inorganic pigments, including synthetic pigments such as Prussian blue and ultramarine and mineral pigments such as cinnabar, red lead, basic lead chromate, lead chromate and carbon. Taking advantage of SEM-EDS’s(scanning electron microscopy and energy dispersive X-ray) Mapping function got the distribution of different elements on samples that could distinguish filler components which include barium sulfate, calcium carbonate, aluminum hydroxide, silica, kaolin, magnesium chloride in ink or paper. The fingerprint information that provid a reliable data has the significance of the future in-depth study in coiling dragon stamps, also provid the ideas and methods for the identification, protection and restoration of the stamp.
