Original Note:
Oxygen, water vapor, and various acids react with the copper and cause it to tarnish. This oxidation, combined with other chemical reactions, results in its natural bright reddish orange color to gradually turn into a deep chocolate brown color known as patina. https://www.thesprucecrafts.com/copper-color-grading-768388#:~:text=Oxygen%2C%20water%20vapor%2C%20and%20various,brown%20color%20known%20as%20patina.
