摘　　要：北京丰台万泉寺遗址位于金中都遗址内,遗址出土金代白瓷样品在形制上符合金代定窑白瓷特征。白瓷胎体成分和锶同位素比值综合研究确定了三种制胎原料,其中:高铝黏土原料的锶同位素比值在0.73左右;白云岩化石灰岩原料的锶同位素比值在0.72左右且钙含量较高;草木灰原料的锶同位素比值在0.71左右,且锶含量在1000μg/g左右。通过釉层的成分分析及胎釉成分的对比研究,发现釉层主要使用高硅原料与白云岩化石灰岩配制而成,并受到了部分熔融胎体的强烈影响,根据与草木灰关联性较强的P_(2)O_(5)含量推断,釉层中可能也含有一定量草木灰。万泉寺遗址白瓷的研究丰富了有关金代定窑白瓷胎釉配方的认识,确认了白云岩化石灰岩为胎釉的主要钙质助熔剂,揭示了草木灰类助熔剂在胎和釉中可能存在各自独立的来源。The Ding kiln is one of northern China’s most representative white porcelain kilns of the 10th-13th centuries A.D.Many scholars have studied it extensively to reveal the complex changes in the formulas of white porcelain of northern China.The use of fluxes is an important issue in the study of ancient Chinese porcelain-making technologies,and several scholars have suggested that the Jin Dynasty was a critical period for the transformation of fluxes in the white porcelain from Ding kiln sites.However,there is still a lack of research on the formulas of the Jin Dynasty white porcelain,especially from the perspective of strontium isotopic analysis on the body and glaze formulas of the Jin Dynasty white porcelain from Ding kiln sites.The Wanquansi site in Fengtai District of Beijing is located within the Jin Zhongdu site,and samples of the Jin Dynasty white porcelain excavated from the site are consistent with the characteristics of Jin Dynasty white porcelain from Ding kiln sites in terms of forms.In our study,three methods—X-ray fluorescence spectrometry(XRF),multi-collector-inductively coupled plasma-mass spectrometry(MC-ICP-MS)and laser ablation-inductively coupled plasma-mass spectrometry(LA-ICP-MS)—were employed to determine and analyze the compositions of the body and glaze and the strontium isotopic ratios of the white porcelain excavated from the Wanquansi site.Three kinds of raw materials used for making the Jin Dynasty white porcelain from the Ding kiln were identified,among which:the strontium isotopic ratio of the high-alumina clay raw material was around 0.73,that of the dolomitized limestone raw material was around 0.72 with a higher content of calcium,and that of the plant ash raw material was around 0.71;the content of strontium was around 1000μg/g.Through compositional analysis of the glaze layer and comparative study of the composition between the body and glaze,it was found that the glaze layer was mainly made from high-silica and dolomitized limestone raw materials,and was strongly affecte
