X-ray emission fluorescence (XRF) analysis of origin of raw materials of light dark reddish brown porcelain and porcelain with black flower on a white background of Dangyangyu kiln

Dangyangyu kiln was an important civil porcelain production place in the North China during the Song Dynasty. In order to find out the source of raw materials of the porcelain body and glaze and their classification relationship so as to correctly distinguish them, we have used XRF to determine the major chemical elements of some porcelain samples with light brown and samples with black flower on a white background. Dynamic fuzzy cluster analysis was applied to the data. Results indicate that the origin of raw materials of light brown porcelain body samples is comparatively more concentrated, while that of the porcelain with black flower on a white background is scattered about. The origin of the body materials of those two kinds of porcelain samples is obviously different. The origin of raw materials of light brown porcelain samples is comparatively concentrated and stable, while that of the porcelain with black flower on a white background is scattered about, moreover, the origin of glaze raw materials and the formula of the two kinds are obviously different. The origin and formula of the light brown porcelain with white glaze in the interior are close to those of the white glaze of porcelain with black flower on a white background, but they are not entirely identical.
