Part 4/8:
Further examination reveals a separated metal component, where one part has turned dark while the other remains shiny. The presenter manipulates the pieces onscreen, trying to understand how they originally fit together. The darkness appears to result from oxidation or some other chemical process, elevating questions about how the metal has changed over time.
The presenter humorously admits uncertainty about whether to clean these objects with a wire wheel or leave them as-is, inviting viewer input—a testament to the community-driven curiosity surrounding these artifacts.
