摘　　要：利用同步辐射显微CT、XRD和EDXRF对西周倗国墓地出土的一枚釉砂开展无损分析,探讨该枚釉砂的制作工艺。结果表明,此釉砂珠的石英胎质较为致密,胎料为研磨很细的石英颗粒,与西方釉砂的内部结构相差较大,暗示该样品不是从西方输入。此釉砂珠的制作工艺为,首先围绕圆柱形内芯制作石英胎,然后施釉,烧制后去除内芯;这种工艺可能受当时青铜器铸造工艺和原始瓷制作工艺的影响。显微CT无损分析釉砂的内部结构的优越性,显示其在釉砂研究中有着广阔的应用前景。Faience is supposed to be the precursor of ancient glass. Studies on Chinese faience are of help in understanding the origin and development of Chinese ancient glass. In this paper, non-destructive methods of SR-pCT, XRD and EDXRF are used to analyze a faience bead from Peng state in Western Zhou period （BC1046-BC771）. The results show that the bead body is composed of micro quartz particles, and the body is denser than that of Western faience. The manufacture procedure can be deduced as follows： based on a cylinder core, the quartz particles were piled to form the body, which was then glazed and heated; after that the core was stripped. This technology was influenced by the bronze and protoporcelain production. Micro CT has great potential to study microstructure of ancient faience.
