What is another word for iron mold?
Pronunciation: [ˈa͡ɪ͡ən mˈə͡ʊld] (IPA) 
Iron mold refers to the buildup of iron oxide on a metal surface, often due to exposure to moisture. There are several synonyms for this term, including rust, corrosion, oxidation, and tarnish. Rust is the most commonly used synonym, and it is typically associated with the reddish-brown color of the iron oxide that forms on the metal. Corrosion and oxidation refer to the chemical reaction that causes the iron to break down and deteriorate over time, often due to exposure to water or oxygen. Tarnish is a term typically used for metals other than iron, such as silver or copper, but it can also describe the discoloration that occurs on iron surfaces due to exposure to air.
