No matter the type of metal, the last thing you want is for it to tarnish. Tarnish causes the surface of a metal to become dull or discolored. Electroplating, which uses an electrical charge to cohere one metal to another, is one of the most effective ways to prevent this kind of corrosion. Here are some ways to recognize signs of tarnish in your metal products and how to avoid it.

Signs of Corrosion and Tarnish

Iron

If an object made with iron is stable, it will be dense and either blue-black or red-brown. If you notice depressions on the metal surface and orange hues on these depressions, this indicates that corrosion has taken place.

Copper

Stable copper and copper alloy artifacts are typically adhesive and smooth. If corrosion has taken over, you will see spots of light green powder.

Silver

Silver tends to be more susceptible to corrosion than other metals. If silver is in good shape, it will look white and metallic. When tarnishing occurs, the silver will mix with sulfur and develop into silver sulfide, which is black.

Preventing Corrosion and Tarnish

It’s a good idea to inspect your metal products for tarnish at least once a month. It’s easier to repair tarnish if caught early. It’s also essential to keep the metal surface dry, as excess moisture is a common cause of tarnishing. Electroplating can also make your metals more resistant to tarnishing and corrosion by providing a barrier that minimizes the object’s exposure to air and water, therefore increasing its durability. The appearance of the metal is also enhanced.
