From: New insights into the Jin Dynasty Ding wares based on geochemical analysis

a Scatter plot of trace element contents of Early and Late Jin dynasty Ding ware bodies. b REE distribution curve. c Scatter plot of REE-La/Yb. This shows a separation between white porcelain samples from the Early and Late Jin dynasties, while Early Jin samples from JCA and JCB kilns share similar characteristics.
