![]() The people that can do it well have a gift that is not easily replicated. Ultimately, the combination of all outside influences change the patinas as they are developed.Ĭreating patinas outside of the natural world is an art form. Who knows, maybe they would be even better if we were on the beach in Florida. We have often said that our patinas are beautiful because of the mountain air and low humidity we enjoy here in Colorado. The humidity in the air, temperature of the space and other chemicals already in the area affect the reactions. In addition to any chemicals used to force a patina, the environment also plays a part. This can cause quite a few problems and loss of a beautiful finish. If the reaction is not reversed, it will continue at a much more rapid rate than nature would allow. When forcing a chemical process, it is equally important to then stop the process. Like our chemistry class in high school, some of the outcomes are expected and others, not so much. Each metal reacts in it’s own way to the different chemicals it comes in contact with. It is possible to add acidity and alkalinity to the surface of a metal to create reactions. When we talk about patinas in the world of design, we are usually talking about a little help from human hands to hurry that process along. Over time, the metal shows age, time and use. Simply said, patina is what metal does when it is completely left alone. Patina is what makes an antique copper pot spot and richen in color. It also rusts a tractor in the field. The metal oxidizes when exposed to air, much like an avocado (or any fresh surface for that matter) begins to turn brown after being cut. Patina is a chemical process that happens naturally when metal is left to the elements. So, I thought I should give you a little Patina 101 to get this blog rolling! We see all sorts of products being sold with “patina” finishes. The word has become such a catch word in the industry. Call now to speak to a metal team specialist for delivery and toll processing.I get asked almost daily to define patina or describe what patinas are. While a natural patina may take five years, a chemical patina can be completed quickly, though it may not have the adhesion, color or the consistency that a natural patina would.Ĭall Vortex Metals today for more information on copper products and copper pricing. What has been discovered is that while patinas can be created artificially, they may not be as reliable as ones that occur naturally. Chemically created patinas are possible. ![]() Overall, the most critical factor is the climate where the copper is placed. In order to create a patina in a short amount of time, artists and scientists have discovered that their success depends on the weather conditions as well as how the solution is applied. ![]() Artists and scientists alike have pursued creating patinas for a long period of time.Chloride salts, present in areas near saltwater, can cause copper to patina differently that copper that is given the chance to patina in landlocked areas or areas near fresh water. Copper near the ocean patinas differently than copper near freshwater sources.This is due to the presence of copper sulfate and how it reacts to the environment. When copper parts are exposed to outdoor weather conditions, such as rain and sun, it creates the greenish hue that results in a patina. If you are interested in copper patinas, here are just a few things that you need to know: As more people have admired the way that copper creates color, they have looked for ways to create it artificially. ![]() The greenish color that has made the Statue of Liberty such a notable part of our country’s history is due to the natural patina that has developed on the copper over time.
