The tradition of hammering copper is a metalworking tactic used for generations to toughen copper sheets. A ball peen hammer is generally used to shape the indentations before the sheet is manipulated into its desired shape. Copper is additionally hammered for aesthetic purposes. Over time, pure copper can start to naturally oxidize in its environment, developing a copper patina. Patina is commonly a green or brown film on the surface of copper, bronze or different comparable metals. The extra depth and dimension created through hammering the surface of copper makes patina much less obvious as it starts to appear.
