Geology & background
Most chrome-looking everyday objects are manufactured by applying a thin chromium plating over another metal rather than using solid chromium.
Chrome plating became especially common in twentieth-century vehicles, appliances, tools, fixtures, and decorative hardware.
How to identify Chrome
- Look for a very bright, mirror-like silver surface.
- Chrome often appears cooler and bluer than silver or stainless steel.
- Plated objects may show scratches, flaking, or a different base metal at worn edges.
- Common objects include tools, fixtures, handles, trim, and decorative hardware.
