Jingdezhen is famous for producing bluish white porcelain in the Song Dynasty, and Hutian kiln is one of the main production sites of the time. The bluish white porcelain produced by Hutian kiln is exquisite and beautiful, and it is known as “false jade ware” and “Rao jade (Jingdezhen belonged to Raozhou government in ancient times)”. Chemical composition and colorimetric characteristics of glaze and body of Southern Song and Northern Song Jingdezhen Hutian kiln’s bluish white porcelain were analyzed by EDXRF and colorimeter in this study. The result shows that the body chemical compositions of Hutian kiln’s bluish white porcelain are basically the same in the Northern and Southern Song Dynasties, which are similar to local porcelain stones, such as the kind from Sanbo near Hutian kiln. The composition of glaze shows that it contains high CaO and a certain amount of MnO and P2O5, indicating that the glaze of Hutian kiln is “calcium glaze”, and a certain amount of plant ash is included in the glaze recipe. The result of colorimetric analysis shows that the main wavelengths reflected by Northern Song and Southern Song bluish white glaze are 500 and 496 nm respectively, and they belong to the green band of visible light. The glaze chemical composition and colorimetric data of Northern Song bluish white are more dispersed, and the Southern Song glaze has a smaller b value and bluer color. The study concluded that the glaze formulation of Hutian kiln bluish white porcelain went through a process from exploration to maturity and stability from the Northern Song Dynasty to the Southern Song Dynasty. The research results not only provide data support for the dating of bluish white porcelain in Hutian Kiln of Jingdezhen, but also provide scientific materials for the inheritance and dissemination of the techniques of making it.
