三峡出土宋元青白瓷产地的判别

Research on the provenance of greenish - white porcelain unearthed in the Three Gorges

为研究重庆地区三峡工程抢救性发掘出土了一批宋元时期青白瓷的产地,采用中子活化方法,分析了28枚三峡出土宋元时期的青白瓷残片和20枚时期相近、窑口已知的青白瓷残片,利用SPSS软件对上述样品胎体的微量元素数据进行统计分析。结果发现:江西产青白瓷的稀土元素含量与福建、安徽、湖北等地差异显著,而Rb、Cs、Hf、Th等微量元素含量也明显不同;三峡出土的青白瓷样品中,除编号为荣阳5和涂山窑5这两枚残片外,其余残片的元素特征与景德镇所产青白瓷颇为一致,拟断定这些青白瓷源自景德镇。

Twenty - four trace elements in twenty - eight greenish - white Song - Yuan dynasty porcelain fragments unearthed in the Three Gorges were analyzed by（neutron activation analysis（NAA） to determine their sites of production. Twenty porcelain pieces previously dated to a similar age,with known sites of origin,were also analvzed by NAA.＇The data obtained were analyzed by SPSS,a statistical software package.It was found that the rare earth element contents in porcelain produced in Jiangxi are significantly different from those produced in other provinces, sued as Fujian,Anhui and Huhei.The Kb,Cs,Hf and Th compositions in these porcelains are also obviously different from site to site.Among the porcelains unearthed in the Three Gorges,all have trace element characteristics similar to those produced in Jingdezhen,except for two pieces,labeled Rongyang5 and Tushanyao5.These results suggest that most of the greenish - white porcelain fragments unearthed in the Three Gorges were very likely produced in Jingdezhen,Jiangxi.
