应用能量色散X射线荧光光谱法测定了16个金元时期钧窑瓷器胎、釉样品的化学组成。由结果可知:金元钧瓷胎具有低硅高铝的北方瓷器特点,釉则多为钙碱釉。金元时期样品与北宋时期钧窑瓷器胎釉化学组成比较,金元时期钧窑样品的化学组成变化较大,从因子分析散点图可见,北宋钧官窑样品化学组成变化不大;金元钧窑与北宋钧民窑样品制作工艺上存在继承和发展的关系,但金元时期对原料选择和配方的控制已不如北宋时期严格,反映出金元时期的钧窑已处于衰落阶段。

EDXRFS was applied to the study of composition of body and glaze of 16 samples of chinawares produced from the Jun Kiln in the era of Jin and Yuan dynasties. The composition of the body was shown to bear the characteristic of high alumina and low silica contents of northern chinawares, while the glaze was found to have the composition of CaO-K2O-SiO2-Al2O3 system. In addition, close similarities in compositions of the body and glaze were found between the chinawares produced from the Jun kilns of the Jin and Yuan dynasties and of the North Song synasty. As shown in the scattergram of factor analysis, the difference in compositions of samples from Jun kiln of the Jin and Yuan dynasties was very significant, while the difference in compositions of samples from the official Jun kiln of North Song dynasty was very small. There was the relationship of inheritance and development of technologies between Jun kiln of Jin and Yuan dynasties and Jun kiln run by local people in North Song dynasty; and the control and monitoring of raw materials, directions and technologies in the production of chinaware of Jun kiln in the Jin and Yuan dynasties were found less strict than in North Song dynasty, which revealed that the production of Jun kiln in Jin and Yuan dynasty was coming to a declining period.
