秘色瓷是越窑青瓷中的精品，也是皇家御用的越窑青瓷。长期以来秘色瓷的研究只限于历史文献记载，直到法门寺实物的出土，才使得其真面目公诸于世。但是秘色瓷的科学识别，产地以及烧造工艺仍是没有统一论断。由于标本短缺和分析方法单一，目前采用自然科学手段研究的工作较少，主要集中于单个窑口的胎釉组成。但烧制气氛、烧成温度以及胎釉物相等因素对秘色瓷制瓷工艺变化起着至关重要的作用。近年来各种技术在古陶瓷中的成熟运用和秘色瓷相关的考古发掘不断出现，为科学的研究秘色瓷提供了技术保障和实物依据。本项目拟收集上林湖地区后司岙窑址、荷花芯窑址和寺龙口窑址晚唐至北宋时期的秘色瓷与越窑普通青瓷，采用共聚焦XAFS，XRF，INAA和XRD等多种核分析技术系统的研究秘色瓷釉中Fe价态的变化和胎釉微量元素的组成，分别从纵向和横向两方面研究秘色瓷历代不同窑址间制瓷工艺的特征，以便为秘色瓷的鉴定和恢复传统秘色瓷工艺提供科学依据。

The Mi’se celadon is the most outstanding and used for emperors in Yue kiln. The research on the Mi’se celadon has long been limited to historical literature, so it is not clear. Until some unearthed remains at Famen temple, the Mi’se celadon is really known. But so far the scientific definition, origin and firing technology of the Mi’se celadon have not the final judgment. Due to the specimen scarce and the single analysis method, the research on the Mi’se celadon in natural science is less, mainly focused on the chemical composition of body and glaze in the single kiln. But the firing atmosphere, firing temperature and phase structure play an equally important role in making technology of the Mi’se celadon. In recent years, various nuclear analysis methods have maturely been applied in ancient ceramics and the relevant archaeological excavations appear constantly, which provides technical support and physical basis for the systematic and scientific study on the Mi’se celadon. In this project, the Mi’se celadon and common porcelain in Housiao kiln, Hehuaxin kiln and Silongkou kiln of Shanglinhu district from the late Tang dynasty to the Northern Song dynasty are the major research objects. The valence fluctuation of Fe ions and trace elements compositions of body and glaze are studied by various nuclear analytical techniques, such as Micro-XAFS, XRF, INAA, XRD and so on. The characteristics of the making technology of different kiln sites and different eras are separately studied from both vertical and horizontal aspects, so as to provide a scientific basis for the identification and restoration of the Mi’se celadon.
