Patina Process

What it is.

A patina is a tarnish, produced by chemical processes, that forms on the surface of many types of metals. When exposed to the elements, a coating of various chemical compounds, such as oxides or carbonates form on the surface. A patina showing rich shades of browns and grays can take decades to acquire. However, at La Bastille Metal Works, we utilize years of experience to achieve the desired level of patina, treating each project like a piece of fine art. Some companies consider a custom patina something as simple as spraying chemicals on metal haphazardly. Our methods are much more refined and exact. Getting the exact level of a patina can be a difficult and painstaking process. Some metals, like zinc, require this oxidation to be stable.
