Définition

• Relief Etching.  A method of producing raised relief by dissolving away all incuse surface area with acid leaving the wanted raised area undisturbed. This is accomplished by coating the surface with a wax forming an etching ground and scraping away the area to have the incuse area eaten away by acid. Such a piece has no modulated relief – it is a flat original surface with incuse design areas.  See acid etching, photoetching.
