安徽繁昌窑青白瓷化学组成的WDXRF分析研究

安徽繁昌窑五代时期(AD907-960)创烧青白瓷,是目前已知的我国最早烧造青白瓷的窑场。北宋中期(AD1023-1085)后,繁昌窑迅速衰落,对其衰落原因,目前尚不清楚。文章运用波长色散X射线荧光光谱法(WDXRF)分析了繁昌窑青白瓷胎的化学组成,结果显示北宋中期时繁昌窑瓷胎的主微元素化学组成均发生了较为明显的改变。结合中子活化分析及瓷釉研究的结果来看,这种改变应是因其制瓷原料或胎料配方发生变化引起的。同时,这种瓷胎化学组成的变化也是导致繁昌窑北宋中期产品质量下降并最终迅速衰落的主要原因。

Chemical composition analysis of bluish-white porcelain unearthed from Fanchang kiln, Anhui province by wave disperse X-ray fluorescence

Fanchang kiln was the earliest Chinese bluish-white porcelain kiln which first fired this special porcelain class as early as in Five Dynasties (AD 907-960). However, this important kiln declined rapidly in the middle North Song dynasty (AD 1023-1085). As to the decline reason, it is still not clearly identified till now. In order to find the truth, wavelength-dispersive X-ray fluorescence (WDXRF) was used to determine the elemental abundance patterns of its porcelain bodies in Five Dynasties, the early North Song dynasty and the middle North Song dynasty. The analytical results indicate that the chemical compositions of major, minor and trace elements in porcelain bodies changed greatly in the middle North Song dynasty. Combined with the results of INAA and glaze study, this change in elemental composition should be caused by the change in porcelain raw materials or body-making crafts. Meanwhile, it was just this change that led to the quality decline of raw material and rapid collapse of Fan-chang kiln in the middle North Song dynasty shortly after its establishment.
