A Brief Comparison Between Verdigris And Patina

A wire mesh is used for numerous industrial as well as architectural purposes. Among the many wire mesh materials, copper and brass mesh has a peculiar feature that makes it quite unique. It develops a layer on its surface known as verdigris. In this blog, this term will be explored in detail along with the term patina, as the two are often used interchangeably. Lastly, the blog will expand on where verdigris is useful and where it can be detrimental.

What Is A Verdigris?

With prolonged exposure to air and the elements, copper, brass and bronze meshes develop a thin layer or coat on the surface. Known for its trademark greenish-blue hue, this coating is known as a verdigris. 

What Is Patina And How Is It Different From Verdigris?

Although patina is often used to describe the greenish-blue hue of verdigris, it is technically a different term. A patina is defined as any coating or layer on a metal’s surface. Verdigris, on the other hand, is a more specific term assigned for the bronze, brass and copper surfaces. 

Applications Of Verdigris

Verdigris is best employed in aesthetic applications such as:

- Furniture: Verdigris or faux verdigris is often used in furniture like coffee tables to create a classic, vintage look. 

- Wall decor: The bluish-green tinge of verdigris can be an excellent addition to any room as an accent colour.

- Outdoor furniture/Sculptures: Since outdoor sculptures and furniture are already exposed to the elements, an added layer of verdigris protects them as well as improves their aesthetic value. 

When Is Verdigris Undesirable?

Lastly, verdigris is not desired in industrial settings, as it is created due to a chemical reaction. Therefore, it can end up damaging the wire mesh over time. Hence, it's best to go for a more corrosion-resistant wire mesh in this case.
