Brass

Brass will corrode in the presence of moisture, chlorides, acetates, ammonia, and certain acids.This often happens when the copper reacts with sulfur to form a brown and eventually black surface layer of copper sulfide which, if regularly exposed to slightly acidic water such as urban rainwater, can then oxidize in air to form a patina of green-blue copper sulfate.
