耀州古瓷釉层呈色机理的质谱研究方法
Mass Spectrometric Methods for Colorative Mechanism Analysis of Yaozhou Porcelain Glaze
Abstract
采用实验室自制飞秒激光电离飞行时间质谱(fS-lI-TOfMS)对唐代、五代、宋代、金代以及明代等五个朝代的耀州窑古瓷片釉层进行多元素同时分析,研究其呈色机理,以过渡元素为重点考察陶瓷釉层中所有可能着色元素的着色效果。推测耀州黑瓷烧制采用的很可能是CO-Cr-fE-Mn系黑色釉料;明代白釉形成的主要原因是fE元素含量低,还有可能与nI元素有关;釉层中P元素含量增多会导致釉色偏黄。毫无疑问,这一系列发现是对整个耀州瓷体系釉层呈色机理的重要补充。 An in-house-built femtosecond laser ionization time-of-flight mass spectrometry(fs-LI-TofMS)has been applied to the multi-elemental analysis of porcelain glaze from Yaozhou kiln.The samples are selected representing products of different dynasties,including Tang,Five,Song,Jin,and Ming Dynasty.For exploring the colorative mechanism of Yaozhou porcelain through the elemental analysis of the glaze,the effects of all potential coloring elements,especially transition elements,were considered.There was a speculation that the typical Co-Cr-Fe-Mn recipe was used in the fabrication of Yaozhou black glaze;the low content of Fe and high content of Ni resulted in the porcelain of white glaze;an increase content of P could lead the porcelain to be yellow-glazed.Undoubtedly,this research is an important supplement to the study of the colorative mechanism of the Yaozhou porcelain system.
