摘要
荣成博物馆所藏的一件清道光青花瓷杯,除青花绘画部分外,该器物釉面遍布细网状开片。采用超景深显微镜、扫描电镜及能谱等对样品分析研究得出,青花层中有呈针状晶体簇钙长石相,以及颗粒状铝酸钴(CoA1_(2)O_(4));在非青花透明釉层分布较多未熔融石英颗粒,而在青花区域较少。笔者推测在烧成冷却过程中,因大量未熔融石英的晶型转变和膨胀系数因素造成非青花区开片;因青花料中钴、锰、铁等助熔剂存在,残留石英较少,青花区域没有开片。
One bluerand-white porcelain shard during Qing Daoguang is collected in Rongcheng Museum.Crackling occurs in the glaze as a decorative feature.The crackle mainly appears in the transparent glaze,whereas the crackle is hardly to be found in the blueand-white painted area.According to the results of Ultrardepthoffield Microscope and SEM-EDAS,the blue-and-white area in the glaze contains needlelike anorthite crystal and granular cobalt aluminate(CoA1_(2)O_(4));there are more.unfused silica particles in the non-lue-andwhite transparent glaze area,and less in the blueand white area.Based on these results,it is deduced that cracks are produced in response to different cerystal transformation and shrinkage ratios of unfused siliea that occur during the firing and cooling process in the nonblue-and-white area,but the blueand-white area contains less silica paricles because of the fluxes such as cobalt,manganese,iron.
