I would suggest using a very fine piece of steel wool to the wire pieces and then washing with a paste of baking soda and a really good rinsing. I usually take my wire and use a green scouring pad to draw the wire before I use it. I also will oxidize my wire before wire wrapping with it. Mind you your hands will turn black from working with the oxidized wire but it will wash off and go away within a day or two. This method also affords the ability to buff out the high points and get some really nice contrast to bring out the wire wrap design.
My inlaws had the same issue every time they cleaned the sink. It will get back to a patina eventually. When cleaning try using a solution of water, a little white vinegar and a couple of drops of antibacterial hand or dish soap. Apply it with a spray bottle and use a soft sponge. Good Luck! I have cleaned the pieces thoroughly, however, they are oxidized unevenly and spotted - some parts are black, while others do not oxidize much.
Any suggestions on how to oxidize more evenly? How nice to see such a thorough list of safety gear and supplies -- I never think to pull these things together until I'm mid-mess and then I'm scrambling.
Now I can just put most of these things together in a kit with a list of everything I need and I'll always have what I need at hand. Nicely done. We just bought an old copper sink and I cleaned it with "bar keepers friend" and It completely lost all of it's patina!
Thank you so so much! I thank you for this informative lense. I mean hard boiled eggs? Hard to justify using 3 eggs since my family goes through a dozen a week. I will be adding to this lens very soon!

Eggs are hard boiled and then crushed to pieces in a re-sealable plastic bag or container while they are still hot. The copper is then placed into the bag and sealed for minutes to hours, depending on the desired shade of brown patina.
The longer the incubation time, the darker the brown color. This method is ideal for small copper items, but large ones are difficult to manage through this technique. Miracle-Gro plant fertilizer is an excellent oxidizer of copper.
For a blue patina, mix one part Miracle-Gro with three parts water for a solution that you can spray or wipe onto the copper. For a green patina, mix one part Miracle-Gro with three parts red wine vinegar. A patina will form within 30 minutes and become permanent within 24 hours. Soaking copper in white vinegar and salt will create a blue or green patina. Other ways of doing this are to bury the copper in sawdust or crushed potato chips soaked in white vinegar.
The longer the copper is buried, the darker the patina becomes. Spray the copper with a solution of salt water and then place the copper in a container that contains non-detergent ammonia. The copper should not be touching the ammonia liquid, but should be raised above it.
The sealed container will trap ammonia vapors that will then make contact with the copper. Be careful when handling ammonia: wear protective gloves, wear safety goggles and be near water in case you need to rinse ammonia off of yourself. Also, do not sniff ammonia and use ammonia outdoors or make sure the room is well-ventilated. There are ways to allow the patina to form naturally without applying chemicals to it.
Exposing the copper to outdoor conditions will help patina to form. Outdoor conditions include fog, rain, snow, and heat. Leaving the windows open will change the temperature and moisture content of the room, so any copper objects in that room will also experience the changes.
You can purposely leave copper furnishings next to sources of heat and moisture, such as in the kitchen next to the stove or the back of the refrigerator. Leaving copper next to a window so that it receives lots of sunlight will expose the copper to natural heat. The patina that forms from artificial methods can be easily brushed off, so it must be sealed to be kept permanent. Sealants can be wax, lacquer or a proprietary mixture of chemicals.
Jewelry-making and craft stores carry multiple brands of sealants for protecting patina. Since patina forms through chemical reactions between copper and molecules in the air, preventing the air from reaching the copper will stop any more patina from forming. Applying a sealant can also be a way to keep the patina that you like, preventing it from changing further.

The products that result from Equations in the previous section each has their own shades of color: Malachite: dark green to blue Azurite: blue to purple Brochantite: dark green to emerald Depending on what combination of these three is present, the color of the patina can vary from shades of green to shades of blue.
Temperature Chemical reactions happen when molecules move and collide with each other. Impurities in the Copper Copper ore taken from the ground has many impurities in it. Air Pollution In Equation 6 above, copper oxide reacts with sulfur oxide and water to form brochantite, which gives a greenish color to patina.
Here are a few more buildings that feature copper patinas in various shades of green: Berlin Cathedral The Berlin Cathedral is one of the most recognizable buildings in Berlin.

How to Create Your Desired Patina Since we know the chemical reactions that cause the different shades of color in copper patina, there are ways that we can affect what color patina becomes and how fast patina forms. In fact, the green color that it develops overtime is made up of a layer of patina, which serves as it shield.
The transformation of copper from shiny, reddish brown to green is actually the most popular type of patina formation. This aging process is generally known as oxidation. When a material, organic or inorganic, is exposed to oxygen, the oxygen molecules combine with the molecules that make up that material and create a chemical reaction.
The kind of chemical reaction depends on the type of material involved. For instance, diced potatoes or fruits turn brown when exposed to the air. Iron rust in a moist environment. Copper, on the other hand, experiences oxidation rather distinctly. Chemicals in its environment that make contact with its surface also cause reaction, but instead of breaking down on a molecular level overtime, it creates a layer of protection that prevents those chemicals from further digging into its core.
A lot of other elements and substances can cause the same reaction on metals. Quite many chemicals, apart from those that are naturally present in the air, can oxidize copper, including ammonium chloride crystals, copper sulfate and ammonium sulfate.
I want to patina an item that is too big to soak and I don't think a liquid will work. The item is a plastic ceiling fan blade. I want to cover it with copper leaf. Is there a way to do this? You can buy paints with copper and other metal powder in them, paint on a few layers of the paint and let it dry, then you can patina the object using a shop bought solution or make your own vinegar, salt, ammonia, etc. Not Helpful 13 Helpful After 24 hours it had a lot of turquoise and green patinas, but it all wiped off, leaving dull copper.
Why did it wipe off? A patina is not like a paint. It wears off. It always wears off. You can seal it with microcrystalline wax, but it won't stop a patina from eventually wearing off.

So if you use a half cup Miracle Gro, use one and one third cups water.
