を打ち破るものである。As described above, the age hardening method for a pure gold material according to the present invention can obtain various hardnesses even for a decorative article requiring casting or ordinary brazing, and therefore, various pure gold materials can be obtained. This is a very good idea that can be used for ornaments. In addition, since the hardness of a work-hardened product of hardened pure gold can be further increased, it breaks the image of pure gold that is originally soft.
