Chalcography is a relatively rare term that refers to the art or process of engraving on copper or other metals. However, there are several other synonyms that can be used to represent the same meaning. For instance, Intaglio is an Italian term that is commonly used in the art world, which means "to cut into". This term is typically used when referring to the technique of engraving. Etching is another synonym, which refers to the process of creating an image on a metal plate through acid or chemical erosion. Engraving, carving, and incising are also synonyms that are frequently used to represent the art and process of chalcography.
