利用能量色散X射线荧光(EDXRF)探针, 对一批金元时期的钧瓷样品进行了线扫描分析, 以研究钧瓷胎釉间薄层物质的性质及其它相关问题. 结果显示, 胎釉间薄层物质的化学组成介于胎釉之间, 因此其应为在烧制过程中形成的反应层. 分析还发现, 反应层中的K2O含量高于瓷釉和瓷胎, 与其它氧化物均有不同. 推断反应层中K2O含量高的现象, 是瓷釉和反应层中特定的SiO2和Al2O3组成, 硅酸盐玻璃的特定网络结构, 以及SiO2, Al2O3及K2O在玻璃体中的作用和特性等因素的综合作用结果, 而非单纯的K＋具有较强的渗透能力所致.

Some Jun Porcelain samples in Jin and Yuan dynasty, that have a thin layer of substance between glaze and body, were analyzed by EDXRF (energy dispersive X-ray fluorescence) line scanning technology, to study the character of thin layer between glaze and body of Jun Porcelain. The result shows that the chemical composition of the thin layer is just between that of glaze and body. So it is concluded that this thin layer between glaze and body is a reaction layer which formed in the process of porcelain fire. Meanwhile, it is revealed that the K2O content of reaction layer is higher than those of glaze and body, and this phenomenon is different from those of other oxides. It is concluded that the phenomenon that the K2O content of reaction layer is higher than that of glaze and body, is the synthetical result of several factors, including the content of SiO2 and Al2O3 content in glaze and body, the structural character of glass, and the effect and speciality of SiO2, Al2O3 and K2O in glass, but not the result of the only factor that the penetrating capacity of K＋ is strong.
