What Causes Tarnish on Precious Metals

Tarnish on precious metals is caused by a chemical reaction between the metal and its environment. Silver and copper are most prone to tarnish, due to oxidation. Humidity and moisture can worsen the process, causing metals to lose their luster.

To avoid tarnish, store metal objects in airtight containers or anti-tarnish bags. Keep them away from sulfur compounds like rubber bands and certain types of paper. Clean and polish the metal surfaces with specialized cleaning agents.

By taking preventive steps, we can maintain the beauty and shine of our beloved possessions. Let us protect our metals from tarnish and relish their eternal radiance for years to come.

The Chemical Reactions Involved

Tarnish is caused by chemical reactions that take place when metals like silver and copper come into contact with air or chemicals. These reactions can change their appearance and properties. To understand them, let’s explore the different types of metals and their reactions with common tarnish-causing agents.

Silver reacts with sulfur compounds in the air to form silver sulfide (Ag2S). The result? A dark or black tarnish. Copper reacts with oxygen to form copper oxide (CuO), which starts off as a reddish-brown coating before turning green. Brass, made up of copper and zinc, has similar reactions, forming tarnish from copper oxide and zinc oxide (ZnO). Gold is less reactive and so doesn’t tarnish easily. It stays corrosion-resistant and keeps its luster.

Humidity, temperature, and air pollution can all speed up tarnishing. In humid environments, oxidation rates are higher so tarnishing is faster.

Take the example of Queen Victoria’s antique silver necklace. It lost its shine due to tarnish, no matter how much the experts tried to clean and polish it. They discovered that sulfur compounds in Queen Victoria’s environment had a major role in the tarnishing process. This shows how even historical items are affected by chemical reactions over time.
