The content of the 30 coloring elements in Ru porcelain is determined by neutron activation analysis (NAA), which showed that iron is the major coloring element. Mossbauer spectroscopy analysis shows that the iron element in the glaze exists in the form of structural iron (Fe2+, Fe3+). The quantitative relationship between the main wavelength of glaze in various colors and the relative content of structural iron (Fe2+/Fe3+) is determined. Thus the coloring mechanism of Ru porcelain is investigated entirely.展开更多

It is found that a midst layer with great variety of elemental contents exists from glaze to body. Furthermore, every elemental content changes continuously and each has different shapes with different jumping-off points and end- points. It is certain that the midst layer is formed during the process of porcelain firing, when vitreous glaze infiltrates into the surface of porcelain body. It also well fits the phenomenon observed through different microscopes (stereo-microscope, polarizing microscope and SEM).展开更多
