本文通过科技手段对在杭州萧山牛面山窑址采集的带有黑色外层的印纹硬陶样品进行了测试分析,根据其光学显微照片,将其分为三类,初步揭示了黑色外层的成分、性质,探讨了其原料及形成工艺,并初步分析了硬陶外层黑釉与原始瓷釉的关系。本文将为深入研究春秋战国时期的制陶技术、深入探讨南方地区印纹硬陶与原始瓷之间的关系提供重要的参考资料。 In this paper, we test and analyze the enamel samples with black outer layer collected by NiuMianShan kiln site in Xiaoshan, Hangzhou. According to their optical micrograph, they are divided into three categories, The composition and properties of the layers were discussed. The raw materials and forming process were discussed. The relationship between the black glaze and the original enamel was also analyzed. This article will provide important reference for further researching the pottery making technology in the Spring and Autumn Period and the Warring States period and deeply discussing the relationship between the printed hard pottery and the original porcelain in the south.
