耀州古瓷釉层呈色机理的质谱研究方法

摘要

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 dy-nasties,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.%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。
