Patina is actually a film on the surface of bronze or related alloys (created by oxidation over a many years as well as by way of a chemical type process); a sheen on wood pieces of furniture that is generated by age, use, and buffing; or any such developed change of the finish through aging and exposure. On metal, patina is a layer of different chemical substances like oxides or carbonates formed on the surface during being exposed to the sun and rain (weathering). Patina pertains to built up alterations in surface texture and color which result from normal utilization of an object for instance a coin or an article of home furniture over time.
Patinas are limited to bare surfaces and they are breakable (that is, they could flake away). One explanation bronze is really highly valued in sculpture is the fact that it’s patina protects or guards it from additional corrosion. This natural patina is strong and seldom exhibits a propensity to flake. Brass is also resistant to deterioration, however it is, over time, not as attractive because local pitting reveals next to the shiny background.
The term “patina” comes from the Latin for “shallow dish”. In reality, patina can easily mean virtually any fading, darkening or other indications of age, which are thought that they are natural and/or unavoidable.
The chemical process through which a patina forms is named patination, and a masterpiece of design covered with a patina is considered patinated.
The natural green patina which develops naturally on copper and bronze, at times called verdigris, typically is made up of mixture of chlorides, sulphides and carbonates. copper carbonate or copper chloride. Atacamite is another name for the patina substances. Verdigris is usually more exclusively the synthetic form and may be developed on copper with the addition of vinegar (acetic acid). Such a verdigris is not able to withstand water and will not last on the outside of a building like a “true” patina. It is alternatively typically used as pigment.
An example of a patina is a organic green surface surface produced by gradual chemical type modification of copper, producing a basic carbonate. It is able to form on pure copper things as well as alloys which contain copper, like bronze or brass.
A patina covering requires several years to establish under natural weathering. A copper roof can patinate faster when compared to a copper vertical surface, because of the longer dwell time of water on the surface. Buildings in seaside / marine locations will weather and develop a patina coating more quickly than those in away from the coast areas. For instance, a brand new copper facade in central London will most likely not produce a “standard” green patina for after 50 years.
Facade cladding (copper cladding) along with alloys of copper, e.g. Brass or Bronze, will certainly weather in different ways to “100 % pure” copper cladding. Even a lasting gold coloration is feasible with copper-alloy cladding. Take a look at Colston Hall in Bristol, or the Novotel at Paddington Central, London. There you can see some colors that one might not have expected from copper cladding.
Artists and metalworkers often deliberately add patinas as a part of the original design and decoration of art and furniture, or to simulate antiquity in newly-made objects.

Copper patina is a description of the long-term effects of the atmosphere on copper. The environment attacks the surface of the copper, which causes it to oxidize. This is known as weathering. In time, the weathering creates a patina coverage that resists these corrosive atmospheric components. Weathering is dependent on the environment. Dry environments take much longer to react than moist ones. If an environment is too dry, the patina will not form. The bright copper appearance lasts only a brief time in most conditions. Over a period of months, the copper will darken and will remain this way for about five years. The “statue of liberty” patina does not develop around the 15th year or so.
Some manufacturers offer a lacquered finish which will wear off in time. Ultimately, the best finish is the patina, which is antibacterial and easy to maintain. In time, copper will darken to the color of an old penny. Keep in mind that copper never ages evenly. Copper kitchen sinks do not turn green, despite popular belief. If you are looking for a uniform patina in a copper sink, rethink your choice. To form an even patina in a copper sink is simply impossible. If you are considering a copper sink with no finish at all, or raw copper, be patient. Natural copper will not age overnight. It will take weeks or months for this process to occur. When the copper becomes caramel colored, it will look luxurious and be easy to care for.
They way you should take care of your copper sink depends on the kind of patina it has developed. For a natural copper finish, you only need to clean it with soap and water. If you want to keep the natural copper look without allowing a patina to form, you can buy special wax to apply periodically to seal the finish. Soap and water is also recommended for sinks that already had a patina when they were installed. Whether the sink already had a patina or you allowed it to develop one, acidic foods can remove a small portion of the patina. If this happens, just leave that section alone, as it will develop a patina to match the rest of the sink in time. Specially made cleaners are available for copper sinks that are polished but should not be used on other kinds of copper. A copper sink should always be kept dry after use. If you do notice water spots, don’t worry, as they will eventually disappear.
Never use an abrasive cleaner as this will affect the patina and could scratch the surface. Foods that are high in acid such as citrus fruits shouldn’t be left in the copper sink, because they will create shiny patches. Keep in mind that copper is a natural material and has the ability to heal itself. Keep the damaged area free of wax, allowing the elements to recreate the patina.You can find accessories for your copper sink at any home improvement store or online. Accessories such as copper fittings, faucets and drains can be purchased at a local plumbing supply store or online.

Now that you have your beautiful copper sink, keeping all of your copper sinks looking beautiful is easy and in most cases maintenance free. How you use your custom copper sink, whether a farmhouse sink, apron copper sink or vessel sink – will help you decide how to care for it. Copper is a metal that changes and evolves with time as it reacts with various elements. You will find that your copper sink will age and look even more beautiful as time passes than the first time you see it. Here we provide you with a few guidelines and suggestions to keep your sink looking beautiful for many years to come.
Copper Sink Care Guidelines by Finish Copper Sink Finishes:
Dark & Clear Brown These finishes are achieved by accelerating the aging process that give some of our copper sinks their distinctive patina colors. We recommend you follow these instructions to keep these finishes looking beautiful.
Copper Cleaners – You don’t need any type of cleaners – in fact you should avoid using any abrasive materials or harsh chemicals on any of our products – these may harm the surface and the finish of your sink.
Hard Water – If you have hard water in your area, keep your copper sink and drain clean and dry by wiping it down with a soft cloth after every use to avoid spotting. Hard water will affect copper as it would any other type of metal, and it will be difficult to remove these spots after they etch the finish. You can also help protect your sink from hard water minerals by periodically applying “Renaissance Wax” to your sink which will help maintain its luster and provide better water runoff.
Acid Foods – Do not leave any acid based foods on your sink for a prolonged period of time such as tomatoes, oranges or lemons. If you do, the acid may produce a shiny spot on your finish. If this happens, we recommend you clean it with soap and water and wait for the finish to recover its patina – the copper will age with time and the spot will blend back with the rest of the copper.
Custom Copper Sink: Natural Reddish Color The finish of a bare copper sink is naturally reddish in color and will vary from one sink to another. Your custom farmhouse sink may present dark spots or streaks due to the nature of the copper itself and the finish of the sink depends on the copper sheet it is made from. The color of the copper will gradually change with time, and it will take on a warm medium patina as it ages. The maintenance for this finish is similar to the dark and clear brown copper finishes, however, we can also lacquer the sink to protect it and slow the aging process. If you want us to apply a protective lacquer coating, please let us know. You can slow down the patina process by applying a protective wax such as “Renaissance Wax” to the copper surface periodically to help maintain the luster and provide better water runoff.
Shiny & Washed Finishes for your Custom Sink These finishes are achieved by an acid wash to obtain a beautiful bright look, but will require more maintenance if you want to keep your sink shiny and bright all the time. To keep your sink bright and shiny, you will need to periodically clean and rebuff your sink with a copper cleaner such as Wright’s Copper Cream . After cleaning your sink, you should then protect the surface with a wax coating or you can also chose to lacquer it with a clear lacquer. If you want the copper finish to change with time and acquire its own unique patina, then all you need to do is wait and the sink will slowly age.
