Copper is a reactive metal. In a process called oxidation, copper reacts slowly in the presence of oxygen, resulting in copper oxide. This is what we call tarnish, which is generally perceived as a brown or black coloration on the surface. Copper reacts with moist carbon dioxide in air to form copper carbonate and as a result, copper vessel loses its shiny brown surface forming a green layer of copper carbonate.
