The production of metal mirrors has evolved from ancient handcrafted alloys to high-tech vacuum deposition and 3D printing.
: In some Indian communities, a 500-year-old tradition uses a specific alloy of tin and copper, melted at 1200 degrees and polished with coconut oil. MegaL – Mirror
The reflective properties of metals are fundamentally tied to their atomic structure. Metals contain "delocalized electrons" that exist in a "sea" or "soup" around atoms. When light waves strike a metal surface, these loosely held electrons vibrate at the same frequency as the incident light, oscillating to generate a reflected wave. The production of metal mirrors has evolved from
To achieve optical quality, metal mirrors undergo rigorous post-fabrication treatments: metal mirrors undergo rigorous post-fabrication treatments:
