Over the years, numerous gold and silver artifacts were excavated from tombs of the Tang Dynasty which gave evidence of the sophisticated metalworking techniques at that time. However, very few of them were studied and the manufacturing process was barely known. In this research, the microstructural analyses including microscopy and SEM–EDS were conducted on a delicate silver cosmetics box excavated from a Tang Dynasty tomb of Xiaolizhuang site. The silver artifact is made up of two symmetrical cambered pieces which were fabricated by alternating hammering and annealing. The shape and surface features were further modified through plastic forming. Afterwards, spinning technique was employed to ensure the interior surface is smooth and has consistent thickness. The surface of the silver box is fully decorated with multiple fine engraving including petals, fish-toe circles, flower pattern, twine pattern and the Tang grass pattern. According to the overlapping status of the notches, the patterns were processed in a certain order by using various gravers. The artifact was brought in its final appearance by gilding to form a thin gold film on the surface. These results overall reveal the sophisticated techniques applied in making the artifact and further enhance the understanding of metalworking practices in the Tang Dynasty.
