A patina is a tarnish produced by chemical processes that form on the surface of many types of metals. When exposed to the elements, a coating of various chemical compounds, such as oxides and carbonates, form on the surface. A patina showing rich shades of browns and grays can take decades to acquire.
At La Bastille, 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 a quick and haphazard spraying of chemicals on metal. 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, and temperature, humidity and a myriad of other factors affect the final process.
Our specialty metals are living alloys and will patina and develop wear patterns. This is precisely why our clients choose the material they choose. Over time, it will change and develop a history as rich and unique as the space in which it resides.
It is possible to polish zinc, but we recommend allowing the metal to oxidize and develop its own beautiful patina, creating a richness in color and character with time. And while we can lacquer our tops upon request, this does not guarantee 100% protection against the natural patina process. It will slow the process but not stop it entirely.
We offer a variety of professional finishes: natural zinc, which is matte silver in hue, and a pre-patinated finish, which provides all of the rustic character of an aged piece of zinc without the extended wait. Please note that the darker the finish, the more noticeable the markings will be as your piece ages.
