Sherds were collected from Hongzhou Kiln covering 8 periods from Eastern Han to Late Tang Dynasty/the Five Dynastied and their bodies were analysed by NAA. The results show that the elemental contents in different samples are quite distinct, even for those in the same period. It means no single element can be used as "fingerprint" to distinguish the period. The curves of the contents of Na, Rb, Ba and Fe varying with lime are very similar, like "U" shape.
对江西洪州窑从东汉晚期至晚唐五代8期400个瓷胎样品进行了中子活化分析,分析结果显示碱金属元素Na和Rb、碱土金属元素Ba及Fe等作为胎的助熔剂元素随年代的变化趋势相似,都呈现出两头高中间低的U字形变化规律,其中Fe作为呈色元素,其含量的高低与瓷胎颜色的深浅是一致的。
