Copper has been used as water-proof roofing material since ancient times, giving many old buildings their greenish roofs and domes. Initially, copper oxide forms, replaced by cuprous and cupric sulfide, and finally by copper carbonate. The final copper sulfate patina (termed verdigris) is highly resistant to corrosion. Copper is the third most recycled metal after iron and aluminum.
It is estimated that 80% of the copper ever mined is still in use today.
