Answered by anubhav694712

Explanation:

Copper tarnish occurs in a multi-stage process that first gives the metal a deep red color, then a black hue and finally the sea-green patina made famous by the Statue of Liberty and world landmarks such as the Berlin Cathedral, Vienna's Belvedere Palace and the Parliament Building in Victoria, British Columbia.

Copper tarnish may be a feature on architectural structures, but it can be an eyesore on copper sinks and pots, and there are ways to remove it.
