Why Has My Brass Turned Pink?
Brass can turn pink due to a process called “dezincification,” where the zinc present in the brass alloy is gradually removed, leaving behind a copper-rich layer. This copper layer, when exposed to atmospheric conditions and humidity, can then develop a pinkish hue due to the formation of copper carbonate or copper oxide on the surface. This phenomenon is more commonly seen in older brass objects or those that have been exposed to harsh conditions, such as high humidity or saltwater.
