Abstract：In southern region, the proto- porcelain have been found in large number and its excavation sites are relatively concentrated, thus its processing technique and origin have been studied thoroughly. However, as to proto-porcelain in northern region, the unearthed sites are scattered in distribution and its quantity is less. So there is limited analysis as to the technology. Since shaanxi zhouyuan relics unearthed a large number of proto-porcelain, it is necessary to give detailed analysis to them. In order to explore the technological characteristic of proto-porcelain of Western Zhou Dynasty which was excavated from Zhouyuan site in Shaanxi province, in this article three-dimensional video microscopy system was used to observe the microstructure and energy dispersive X-ray Fluorescence Spectrometer was used to test the chemical composition of the proto-porcelain body and glaze. The results of microscopic observation indicated that the proto-porcelain body quality was rough and had many unmelting particles and pores; the glaze layer was uneven and distributes many bubbles. The results of chemical composition in the body showed that the content of Al2O3 was between 11.8%～17.21%, SiO2 is 75%～80.5%, K2O is 3%～7.85%. However the content in the glaze of CaO is between 11.08%～23.94%, P2O5 is 1%～3.18%, MnO is 0.24%～1%; the content of MnO, P2O5, K2O in the glaze had improved greatly more than those in the body. The above results showed that the raw materials of proto-porcelain body may use the chinastone which contains more potassium; and the plant ash should be added in the calcareous glaze; the manufacturing characteristic of the proto-porcelain found in Zhouyuan site was still at the primary stage in Chinese porcelain’s history.
