双墩遗址黑陶渗炭工艺初探

Preliminarily exploration to the carbonization technique of the black pottery in Shuangdun site

双墩遗址是淮河流域新石器时代中期的一个重要遗址。该遗址出土了相当数量的黑陶,黑陶的制作工艺有多种,为探明双墩遗址黑陶的制作工艺,采用了XRD、喇曼光谱、重烧试验、显微、岩相、SEM和EDS探针等技术,对双墩遗址出土黑陶和局部发黑陶器进行了综合的测试分析。结果指出,陶器整个表层的黑色物质是炭黑。碳元素沿剖面的分布为:内外表层高而中间低,而内外表层0.6mm范围内炭含量的分布不甚均匀,存在明显的高低起伏,表明双墩遗址主要采用渗炭工艺制作黑陶。

Shuangdun site is a typical cultural site of the middle Neolithic Age in Huai River and a large number of ancient black potteries were excavated at the site.In this investigation many experimental means including XRD,Raman spectrum, refiring experiment,microstructure and petrographical analysis,SEMEDS and so on were used.Based on these results,the following were concluded:the carbonization technique of the pottery existed in Shuangdun site. Meanwhile,part of potteries had been painted with the red pottery coating besides carbonization inside,which made them very special.
