Gold has been admired from the ancient time in all over the world, because it has the characteristic color and is not easily corroded. In ancient Japan, of course, it was the special metal to the ancient people ; but, it had been very rare until the Kofun period. Most of ancient metal objects with gold surface, which were excavated in Japan, were fabricated from copper or copper alloys. Their surfaces were treated by gilding, especially by fire gilding with gold amalgam for obtaining brilliant appearance. Some ancient gold and silver objects excavated in Japan were examined with a X-ray fluorescence analyzer and a scanning electron microscope. The gold composition in ancient gold objects was 17-23K.The suitable composition must have been selected depending on the purpose. Silver of over 92% purify was used for most ancient silver objects excavated in Japan. It was revealed silver brazing was utilized as the jointing technique.

黄金自古以来就受到世界各地的推崇，因为它具有独特的颜色，不易腐蚀。在古代日本，它当然是古代人的特殊金属;但是，直到古坟时期，它一直非常罕见。日本出土的古代金面金属器物，大多是用铜或铜合金制作而成。它们的表面经过镀金处理，特别是用金汞齐火镀金，以获得辉煌的外观。利用X射线荧光分析仪和扫描电子显微镜对日本出土的一些古代金、银器物进行了分析。古代金器中的金成分为17- 23 K，必须根据用途选择合适的成分。在日本出土的古代银器物中，大多使用纯度超过92%的银。据透露，银钎焊被用作连接技术。
