Fig. 6: Principal component analysis reveals compositional distinctions between Ding kiln porcelain bodies from different periods.
From: New insights into the Jin Dynasty Ding wares based on geochemical analysis
a and b show the PCA scores and trace element compositions of porcelain bodies from the Northern Song, Early Jin, and Late Jin Ding kilns. These figures clearly illustrate that the porcelain bodies from the Northern Song and Early Jin periods cluster together, while those from the Late Jin period form a distinct group. (D-NS indicates the Ding Ware samples from the Northern Song Dynasty.)
