Abstract

This study is on method of making Guljigu in New Stone Age. The object of analysis is Guljigu excavated at Jingeuneul and Galmeori site. Guljigu consists of four stages through the traces found on the surface. It arranges external traces by each stage and is classified into fie types through edge and plane. Features of each stage can be described as follows. Technical system of Guljigu has four processes including acquisition of stone materials, preparation of body, the first molding and the second molding. Raw materials were acquired around relics and raw materials had developed stratiform structures. Body was prepared by processing raw materials or detaching it to large flakes. And the first molding was made by vertical and oblique striking, and the second molding was done by a small touch. Finally edge and groove were made. Such an industry system is summarized in two. One is processing gravel itself and the other is processing by detaching large flakes. Each technique was preferred depending on the form of Guljigu and this technique was relatively simpler than technical systems in Old Stone Age. But from the changes of using stonewares in New Stone Age, this technique was obviously advanced. To sum up, method of making Guljigu consists of four stages and this process applied two techniques.
