However, it is also known as a \"green\" metal for the green patina that it acquires due to weathering. Indeed, patinized copper is the architectural focal point of many modern buildings for its natural look. Beyond this, however, copper can truly be cited as the \"green\" metal both for its role in protecting the natural environment through its use in energy-saving applications and for the achievements that have been reali...
