【摘要】 以深黑色花岗石粉为主要原料,碎玻璃和红土作为辅助原料,研制铁系釉,并分析釉成分、烧成制度因素对釉性状的影响.结果表明,深黑色花岗石粉的用量以65%~100%为宜,玻璃粉和红土加入量均以5%~10%为宜.此外,烧成制度影响釉的性状,烧成制度的变化改变铁的相变状态,高温有利于铁的分相和铁质富集析出.配合少量红土和碎玻璃粉,可以制得饴釉、铁红釉、光泽黑釉、花釉,甚至"油滴"釉等铁系釉.更多还原

【Abstract】 Iron-glazes were made of powder of jet black granite(as main content),glass dust and red clay(as auxiliary content).Factors that influenced the character of glaze were investigated,including its component and the heating-up transformations.Results showed that when the amounts of jet black granite and red clay were among 65%~100% and 5%~15%,respectively,the glazes exhibited good performances.Enrichment and phase separation of ion occured easily at higher temperature.Adding red clay and glass dust to powder of jet black granite,could result various iron based glaze,such as iron red glaze,mirror black glaze,furnace transmutation and even "oil spot" glaze.更多还原
