This research focuses to reveal the materials and the manufacture technology of an ancient gold wire excavated in an archaeological site in Japan, and also treats its history in Japan. Japan produces modern gold thread, which is made of the base film with thin gold surface. It is totally different from ancient gold wire. Ancient gold thread excavated in Japan was a strip-twisting wire type. This is the one of"filigrees", which is used injewelry to designate ornaments made from metal wires. Since the compositions of this gold wire were over 95 % gold and 4% silver, the material was soft enough to make it thin. The SEM observation tells us the details of this wire. Firstly, a gold foil, about 15μm in thickness, was made. Narrow strips, about 300μm in the width, were cut out from the foil with a kind of shears or scissors. Finely, a strip was twisted into a fine hollow tube with a round cross-section, which had a diameter of about 150μm. A single seam runs in a helix around the wire. The hollow wire shows deformation easily. Although it is an idea that it originally had silk threads as a core inside, the traces of organic materials were totally disappeared. The special gold earring made by layered gold foils was discovered. This technique was named "gold foil layering technique". It is very interesting thin gold foil was the first important stage of ancient gold wire excavated in Japan.

这项研究重点是揭示一条古老的金属丝的材料和制造技术，该金属丝在日本的档案馆挖掘出来，并在日本对待其历史。日本产生的现代金线是由带有薄金表面的基础膜制成的。它与古代金线完全不同。在日本发掘的古代金线是一种扭曲的电线类型。这是“丝状”之一，它用于指定金属电线制成的装饰品。由于该金线的成分超过95％的金和4％的银，因此该材料足够柔软，可以使其变薄。 SEM观察告诉我们这条线的细节。首先，制成了约15μm的金箔。用一种剪切或剪刀从箔纸上切出狭窄的条，约300μm。细腻的是，将一条带扭成一个圆形横截面的精细空心管，直径约为150μm。单个接缝在电线周围的螺旋中运行。空心线很容易显示变形。尽管它最初以丝线为核心是一个想法，但有机材料的痕迹完全消失了。发现了由分层金箔制成的特殊金耳环。该技术被命名为“金箔分层技术”。这是非常有趣的薄金箔是日本发掘的古代金线的第一个重要阶段。
