东莞村头遗址出土玉石器的片切割工艺研究

Research on the Slice Cutting Technology of Jade Wares Unearthed in the Cuntou Site,Dongguan

东莞村头遗址出土少量玉石器上有片切割工艺的痕迹,通过模拟实验对比研究,可知村头所见片切割工艺包括两种类型,一种是用竹木片切割而成,是由村头古人在当地对废弃石器的一种改制尝试。另一种是采用金属片状工具切割而成,主要发现于石璋及石质优良的小型锛凿类器物上,是在石器制作地制作而成。两种不同的技术传统,提供了商代华南地区不同种类石器的传播与交流的线索。

Traces of slice cutting techniqueology are found on a few jade wares unearthed at the Dongguan Cuntou Site,Dongguan.According to a comparative study of simulation experiments,there are two types of slice cutting techniquenology used on the jade wares unearthed at the Cuntou Site.One is done by the bamboo and wood chips,which is reconstructed on the ancient method as an attempt made by the local ancients to reform the abandoned stone implements.The other is made by cutting with metal sheet tools,which is in the place where the stone tools were produced,mainly applied found in jade ornaments and small-sized hammers and chisels of excellent stone quali-ty.Two different technological traditions provided clues for the dissemination and exchange of different types of stone implements in South China during the Shang Dynasty.
