为揭示银沟遗址出土唐到元代青瓷的原料特征与呈色特点，采用光学显微镜、X射线荧光光谱仪、色度仪和紫外-可见光-近红外分光光度计，研究青瓷胎釉的微观结构、化学组成与釉面呈色。研究结果表明:(1)金代青瓷胎中主要氧化物SiO2、Al2O3含量与其他各代有显著差异。唐代到金代胎中呈色元素TiO2、Fe2O3含量逐渐降低，使得胎色从灰黑过渡到灰白。但是元代胎中的铁含量较高，而钛含量偏低，使得胎色偏黄色。(2)宋代青釉中的K2O、Al2O3、SiO2含量均处于较高的水平，釉高温黏度大，釉中气泡密集并且尺寸不均匀。金代、元代釉中CaO含量较高，釉面多开片。主要呈色元素Fe2O3在唐代青瓷中含量较低，宋代，元代含量较高。(3)五代到元代青瓷釉色从冷色调蓝绿向暖色调黄绿转变，与釉中Fe元素价态和配位的变化有明显关系。
Chemical Composition and Color Presentation of Celadon Excavatd from the Yingou Site
In order to reveal the raw material characteristics and color characteristics of celadon from the Tang Dynasties to the Yuan Dynasties unearthed at the Yingou site,the microstructure,chemical composition and glaze color of celadon body glaze were studied in this paper using optical microscope,X-ray fluorescence spectrometer,colorimeter and ultraviolet-visible-near-infrared spectrophotometer.The research findings are as follows:(1)The content of the main oxides SiO2 and Al2O3 in the Jin Dynasty celadon body differs significantly from other dynasties.From the Tang Dynasty to the Jin Dynasty,the content of the color elements TiO2 and Fe2O3 in the bodies gradually decreased,making the body color transition from gray-black to gray-white.However,the iron content in the Yuan Dynasty bodies is relatively high,while the titanium content is relatively low,making the body color yellowish.(2)The contents of K2O,Al2O3 and SiO2 in the green glazes of the Song Dynasty were all at a relatively high level,and the high-temperature viscosity of the glaze was high,and the bubbles in the glaze were dense and uneven in size.The CaO content in the glazes ofthe Jin and Yuan dynasties was relatively high,and the glaze surface was often cracked.The content of the main color element Fe2O3 in Tang Dynasty celadon is low,and the content in Song Dynasty and Yuan Dynasty is high.(3)The glaze color of celadon from the Five Dynasties to the Yuan Dynasty changed from cold blue-green to warm yellow-green,which was obviously related to the changes in the valence and coordination of Fe in the glaze.
