耀州窑青瓷断代特征比较研究

Comparative Study on the Dating Characteristics of the Celadon of Yaozhou Kiln

耀州窑是历经唐至元五个朝代,以青瓷著称的窑场,研究它历代不同地址出土的青瓷,有助于揭示它的烧造历史和工艺发展轨迹。利用白度仪测量所有样品的L*a*b*色度值,使用手持显微镜测量样本气泡大小并计算出方差,采用能量色散X射线荧光法(EDXRF)测定耀州窑不同朝代青瓷胎和釉的化学组成并进行多元统计分析。结果表明,耀州窑青瓷属于典型的北方"高铝低硅"钙釉青瓷,各个朝代青瓷样本的胎釉特征相互之间基本上都具有继承性,西安市西大街出土的"唐代"青瓷片更符合五代青瓷特征。

Yaozhou Kiln is famous for celadon sintering skill which goes after long period of development from Tang dynasty to Yuan dynasty. Its development track and history of firing can be easily revealed by studying different celadon from different dynasties. The L*a*b* chromaticity values of all samples were measured by a whiteness meter, the sample bubble size was measured by a hand-held microscope and the variance was calculated, the energy dispersive X-ray fluorescence (EDXRF) method was used to determine its chemical composition of celadon tires and glazes in different dynasties 丒 By multivariate statistical analysis, it shows that the Yaozhou kiln celadon is a typical northern "high-aluminum and low-silicon" calcium glaze celadon. The glaze characteristics of the celadon samples from each dynasty are inheritable.The "Tang Dynasty" celadon pieces unearthed from Xi'an West Street are more in line with celadon features in the five dynasties from Tang to Yuan.
