What is a petina finish?

A patina finish refers to the change in appearance that occurs on a material, often metal, over time due to exposure to the elements, aging, or chemical reactions. This natural process can create a unique, often green or brown, layer that enhances the aesthetic appeal of the object. Patina is commonly seen in copper, bronze, and brass, where it adds character and depth. In some cases, artisans may artificially create a patina to achieve a desired look on new items.
