摘要
采用EDXRF、热膨胀仪、光学显微镜和SEM/EDS分析白马窑中三官坑和枫树头两处代表性窑址青瓷的胎釉化学组成、烧成温度和显微结构,讨论其青瓷的组成特征和制瓷技术。结果表明:白马窑青瓷胎土淘洗程度较低,其胎体组成具有"高硅低铝"的特征。青瓷的烧成温度范围在1208℃~1268℃之间,胎体的吸水率小于1.1%,表现出较高的致密化程度。另外,白马窑陶工采用高锰低磷的草木灰为助熔剂制备青釉。釉中分相液滴、气泡和少量石英晶体的存在对可见光产生一定程度的吸收和散射,使得青釉的光泽效果更柔和舒适。
EDXRF,thermal dilatometer,optical microscope and SEM/EDS were used to analyze the chemical composition,firing temperature and microstructure of celadons from two typical kiln sites(Sanguankeng and Fengshutou)in Baima kiln.Composition characteristics and manufacturing technology of the celadons were discussed.It was found that the raw material f or celadon body in Baima kiln exhibited a relatively low degree of elutriation and the body was characterized by"high silicon and low aluminum"in composition.The celadons in Baima kiln were fired at temperatures in the range from 1208℃ to 1268℃,with water absorption of less than 1.1%,showing a high degree of densification.In addition,in the potters in Baima kiln,high-manganese and low-phosphorus plant ash was used as the flux to prepare celadon glazes.Due to the presence of phase-separated droplets,bubbles and a small content of quartz crystals,the glazes displayed light absorption and scattering to a certain extent,so that the celadons look soft and more comfortable.
