These discoveries represent the earliest known tinned iron artifacts in China to date, as well as the earliest tinned iron production remains found anywhere in the world, proving that an organized, systematic craft industry for tin-plated ironwork existed at that time.
While China has a long history of making tinned bronze and tinware, there has long been a lack of reliable historical records or physical evidence to prove early local production of tinned iron artifacts. The newly discovered armor plates can fill this gap, demonstrating that, by no later than the Wu period, local craftspeople in Zhejiang Province had mastered the art of tin-plating iron surfaces. This reflects the region's advanced metallurgical skills at that time, Ge Shuaikun, a researcher at the Shaoxing Institute of Cultural Relics and Archaeology, told the Global Times on Tuesday.
Over the last three years, archaeologists working at the Jizhong ruins site have excavated hundreds of tinned iron armor plates from ancient wells and ash pits. A preliminary investigation confirmed that the surfaces of these plates contain high levels of tin. Subsequent laboratory analyses were conducted in collaboration with the Shaoxing's institute and the Institute for Cultural Heritage and History of Science & Technology at the University of Science and Technology Beijing with methods such as Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS), X-ray Diffraction (XRD), and Micro-CT to deeply examine the samples' materials, structures, and technological traces.

Tin plating effectively prevents rust, making iron armor far more durable and indeed, even after being buried for 1,700 years, many of these tinned plates retain their silvery metallic shine.
Research shows that the craftspeople immersed iron armor plates in molten tin, thus ensuring complete coverage of the surface with a continuous tinned layer. This coating isolated the iron from exposure to air and moisture, dramatically boosting corrosion resistance. Many of the excavated tinned armor pieces still show a clear, bright silver-white finish.
One major reason for tin-plating the armor was to prevent rust. At the same time, the silvery white shine of tinned iron offered a more striking, beautiful appearance, standing out from the typical dark iron armor of the era. This visual distinction may have marked these pieces as a higher-grade military asset, according to an article from the University of Science and Technology Beijing's official website.
The article said that in earlier eras, from the pre-Qin to Han dynasties, tin was widely used as a surface coating on bronzeware and ceramics. Researchers believe the tin-plating of iron armor discovered at the Jizhong ruins site during the Wu period of Three Kingdoms built upon this local tin-coating tradition, representing an adaptation of those techniques across different materials. The process likely benefited from technological exchange among various specialized workshops at the site, including those making bronze castings, iron weapons, and other metallurgical products.
