Verdigris is a noun that refers to a bright bluish-green or greenish-blue substance that forms on the surface of copper, brass, or bronze due to chemical reactions with humidity, air pollutants, or acid exposure. It is commonly formed through the oxidation of copper or copper alloys, giving them a characteristic patina.
The word "verdigris" originates from the Old French "vert de Grece," meaning "green of Greece." It was named as such because in ancient times, Greeks and Romans used a mixture of copper and vinegar to produce a pigment that resembled the natural green color of patinated copper.
In terms of appearance, verdigris can vary from a light turquoise shade to a deep blue-green color, with a characteristic powdery texture. It is often appreciated for its distinctive and aesthetic appeal, primarily seen on architectural features, sculptures, or historical artifacts.
While the formation of verdigris is often considered a corrosive effect on metal, it can also provide a protective layer, acting as a barrier against further corrosion. In artworks or decorative purposes, verdigris is sometimes intentionally induced to enhance the aesthetic value or to replicate the antique appearance.
Though verdigris has a long history in art and architecture, it is important to note that its presence on certain metal objects, particularly those used for cooking or food storage, can be potentially harmful. Consuming food or beverages that have come into contact with verdigris may lead to copper poisoning, which can cause various health issues.

The word "verdigris" originates from Old French "vert de Grece", which means "green of Greece". This term was used to describe the greenish-blue pigment that forms when copper or brass is exposed to air or moisture over an extended period. The "vert" in "vert de Grece" means "green", and "de Grece" means "of Greece". The association with Greece likely stems from the notion that alloys of copper and bronze like those used in ancient Greece were prone to developing this greenish patina. Over time, "vert de Grece" evolved into "verdegris" in Middle French and eventually became "verdigris" in English.
