南宋时期官窑青瓷与龙泉青瓷的对比分析

A Comparative Analysis of Guan Kiln Celadon and Longquan Celadon in the Southern Song Dynasty

随着考古发掘出的实物资料不断增多,南宋时期官窑青瓷与龙泉青瓷因其在外观特征上十分相似而难以区分,从而备受古陶瓷界的关注。为此,采用能量色散X射线荧光光谱仪、X射线衍射仪、扫描电子显微镜等仪器设备对杭州郊坛下南宋官窑和龙泉大窑、溪口瓦窑特征瓷片进行测试表征,对比分析两地瓷片在化学组成、制瓷工艺与外观特征、显微结构、物理性能之间的异同点。结果表明,南宋时期官窑青瓷与龙泉青瓷色度相近,但与龙泉青瓷相比,南宋官窑瓷釉玉质感较强,主要归因于烧成温度较低使得釉中气泡多而小,且Al2O3与SiO2含量分别处于0.4~0.55 mol及3.4~4.1 mol的较小范围内导致釉面多处于半无光的范畴,均增强了釉面的乳浊度。

With the increasing number of archaeological materials, Southern Song Guan Kiln and Longquan Celadon in the Southern Song Dynasty are difficult to distinguish because of their very similar appearance characteristics,which attracted much attention in the field of ancient ceramics.In this paper, energy dispersive X-ray fluorescence spectrometer, X-ray diffractometer, scanning electron microscopy and other instruments were used to test and characterize the characteristic ceramic tablets of Southern Song Guan Kiln from Hangzhou Jiaotanxia,Dayao and Xikou Wayaoyang from Longquan. Compared and analyzed the differences and similarities between chemical composition, technology of ceramic making with appearance characteristics, microstructure,physical properties.The results show that the color of Southern Song Guan Kiln is similar to Longquan Celadonin in the Southern Song Dynasty.but compared with Longquan celadon,the strong semse of jade in the porcelain glaze of Southern Song Guan Kiln is mainly attributed to the lower firing temperature,which makes the bubbles in the glaze more and smaller,and The contents of Al2O3 and SiO2 are in the small range of 0.4~0.55 mol and 3.4~4.1 mol, which results in the glaze being mostly in the category of semi-dull,both of them enhance the emulstion turbidity of the glaze surface.
