If your attic doesn't have any leaks, then the patina (green color) is most likely formed by the reaction between the copper and carbon dioxide in the air, forming copper carbonate. This patina, called verdigris, protects the copper underneath from corrosion.
A green penny can turn green when exposed to the elements, like oxygen and moisture, causing a chemical reaction with the copper in the penny. This reaction forms copper oxide, which is the green coating that gives the penny its green color.
Acid in the rain reacted with the copper to turn it green. That is why there is sometimes green on pennies. Acid in the rain reacted with the copper to turn it green.

No, iron oxide will not turn copper green. The green patina on copper is typically the result of oxidation due to exposure to air and moisture, which forms copper carbonate or copper chloride compounds. Iron oxide itself does not have this effect on copper.
The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
To make copper turn green, you can expose it to air and moisture over time. This process, called oxidation, forms a greenish layer of copper carbonate on the surface of the copper.
Becasue of oxidation!
oxygen.
Copper turns green because of sulfur pollution in the air, forming copper sulfide.
The brown copper(II) chloride absorb water and form the green dihydrate.
Pewter turns it black, Copper does turn your skin green though.
No, hematite doesn't contain copper so your skin will not turn green
To quickly turn copper green, you can use a mixture of vinegar and salt or a commercial patina solution. Simply apply the solution to the copper surface and allow it to sit for a few hours or overnight to achieve the desired green patina.
