A scientific study on the preservation of Han gold and silver-decorated iron belt hooks in the collection of the National Museum of China
In this study,a large-format X-ray fluorescence scanning imaging spectrometer(MA-XRF),a 3D video microscope and a Raman spectrometer were used to analyze and test gold and silver-decorated iron belt hooks as well as their early restoration materials.The compositions of the iron belt hooks'material,the distribution of gold and silver foil,and the fracture loss and the crack positions were determined,and the exquisite decoration was restored.The early restoration materials for the iron belt hooks were shown to be mainly epoxy,sand and pigment for the hook head and epoxy,gypsum and pigment for the hook neck,the vicinity of the hook knob and the hook tail.The chemical structure of the epoxy used was the closest to that of the black epoxy.These results show that MA-XRF,as a new detection method,was effective in image enhancement,disease condition judgment and repair location confirmation.The combination of large-format scanning and single-point acquisition made possible the comprehensive extraction of information about the cultural relics and provides a scientific basis for making conservation and restoration plans.
