关于琢玉工具的再探讨

李澄渊《玉作图》、明宋应星《琢玉图》的砣机与20世纪上半叶的砣机相比,其构造相似。借此上溯追寻古代琢玉机的结构,可分为铜砣几式砣机及原始砣机两种磨玉机。红山文化、凌家滩古遗址及良渚文化时期三地玉人先后发明并使用原始砣机磨制玉器,标志琢玉业从制石工艺彻底分离出来,成为史前社会独立的手工业,出现了第一代专业玉人。

An Ri-discuss about Curving Jade Tools

From the comparison of the emery wheels between two ancient books of yuzuotu and zhuoyutu and the first half of the 20th century,the author of this paper drew a conclusion that they were similar in structure.Backward to the more older time,the emery wheels at that time can be divided into several sorts.The people of Hongshan ancient culture,Lingjiatan relic,and Liangzhu ancient culture.all invented emery wheels,furthermore,they used them to curve jade beauties.This can be a symbol that the jade curving industry has been divided from the stone curving and became a independent handicraft industry in the pre-history,meanwhile,the earliest handicraftsmen came forth.
