A Study on the Composition and Manufacturing Technology of Rivets in Bronze Objects

To completely bond two or more metals, there is a method of applying heat or using a nail. Most bronze containers use nails to bond and repair, which are called rivet techniques. Until now, the manufacturing technology of bronze ware has been conducted by many researchers, but research on rivets used in bronze ware is insufficient. In order to understand the manufacturing technology of bronze ware, research on not only the main body of the container but also each part must be conducted together. In the case of rivets, it is believed that they were made in consideration of the material, color, and economic feasibility suitable for the Bronze Age, and in this study, metallic analysis was conducted focusing on the four rivets excavated. As a result of metal microscope and SEM-EDS analysis, it is judged that the Cu-Sn-Pb ternary alloy and Cu-Ag binary alloy were manufactured using the general casting method. Compared to previous studies, rivets can be divided into (1) 100% pure copper (Cu) (2) Cu-Sn-Pb ternary alloys (Sn, Pb around 10%), and (3) Cu-Ag binary alloys, and this time the analyzed rivets correspond to types (2) and (3). If you study not only rivets but also containers in the future, it will be helpful to understand the manufacturing technology process of bronze containers.
