【摘要】 对佛山石湾清代的两个广钧器皿，通过化学全分析和ＥＤＡＸ、ＤＴＥＭ、ＯＭ、穆斯鲍尔谱、ＤＴＡ、ＸＲＤ等测试方法，研究了它们的组成、显微结构及呈色机理。证实广钧釉是一种石灰釉，而且属低温釉；坯体中含大量的游离石英；其是色是ＣＵ２＋和釉中存在液－液分相的结果，分相液滴对白光散射符合瑞利散射条件，使釉显出带乳光性的蓝绿色调。更多还原

【Abstract】 The two wares of Gung Jun in Shiwan Foshan of Qing Dynasty are deliberated by the chemical analysis, EDAX,DTEM,OM, Mossbauer spectroscopic,DTA and XRD on the composition,microstructure and coloration.The glaze of Guang Jun showed a kind of lime glaze and low temperature glaze.The coloration is Cu2+ and liquid-liquid phase separation.The phase separation liquid drops are conformed to Rayleigh Scattering Law and that makes the glaze green-blue with opalescence. Large amout of quartz exists in the body.更多还原
