Abstract: In this paper, the characteristics of Southern Song Guan Kiln and Longquan Ge Kiln's glazes were characterized byenergy dispersive X-ray fluorescence (XRF) spectrometer, X-ray diffractometer (XRD), scanning electron microscopy (SEM) and so on from Hangzhou Jiaotanxia, Longquan Dayao and Xikou Wayaoyang. The results show that the glaze color is similar due to the similar content of Fe₂O₃ in the both glaze composition, also the L*, a*, b* values of the glaze are similar. But the smaller size of bubbles in the glaze of Southern Song Guan Kiln and the concentration of bubbles in the glaze at about 10 microns. Combined with the superposition effect of unmelted fine quartz crystals in the glaze, the diffuse reflection effect of the glaze is enhanced, which results in the glaze being mostly in the category of semi-matte and effectively enhances the jade texture of the glaze.
