Definition: Anodine is a type of metal that contains iron oxide, giving it its characteristic reddish-brown appearance. It is commonly used in the manufacture of jewelry, decorative elements, and other applications requiring high-heat treatment. The term "anodine" is from the Greek meaning "red," which may have originated with reference to the process of heating an object to a state of high temperature, such as creating iron oxide, which gives it a reddish-brown color.
