Tag hinzufügen | Zusammenfassung: | Different enameling recipes can give the same visual appearance. The identification of the coloring agents and the silicate matrix of the glazes is necessary to compare artifacts. Our questions concern porcelain and enameled metal objects, produced specifically for the Emperor and his court. The analysis must be non-invasive and be carried out in the places of conservation of the objects. Our 20-year experience of studying ancient glass, ceramics and metal objects in a non-invasive way has led to focus analyzes on blue, white, yellow, green and red/pink enamels using two mobile analysis techniques, X-ray fluorescence and Raman micro-spectroscopy. These complementary methods identify specific coloring/opacifying elements and phases (yellow and green: pyrochlore based on lead, tin or antimony; pink: gold nanoparticles; white: lead-calcium arsenates; blue: cobalt, Asian or European; red: hematite or copper nanoparticles). The effort focuses on the comparison of innovation dates in Europe and in China. |
