Why bare copper becomes dull?
Bare copper becomes dull due to the formation of a layer of copper oxide on its surface when it reacts with oxygen in the air. This oxidation process creates a tarnished appearance, often referred to as patina. Additionally, exposure to moisture and environmental pollutants can accelerate this dulling effect. While the oxide layer protects the underlying copper from further corrosion, it can be undesirable for aesthetic or electrical conductivity purposes.
