However, the process can be sped up by applying chemical salt solutions to the copper which will cause an instant patina. With regular exposure to air and moisture, you can expect to see a rich, green patina on your copper in around one year. In drier climates, it can take up to six months for the patina to fully develop, but the process can be accelerated by cleaning the copper regularly and exposing it to air and moisture. In warm, humid air a rich, brown patina can form on copper within a week or two. The rate at which copper will patina can vary depending on different factors, such as humidity and air flow. If you wish to retain the patina, use a wax or lacquer to seal it. Once you are satisfied with the way it looks, rinse the piece off with cold water and dry it. If you wish for a more weathered appearance, repeat the process. Take the item out and then rub it with a small cloth using circular motions. Then, dip your copper object into the solution and let sit for 5 minutes.

First, take a cup of white vinegar and mix in 1 tablespoon of salt.

Making copper look old quickly can be easily achieved by using a solution of equal parts white vinegar and salt. Clear coats can be either water-based or oil-based, depending on the desired patina. This method is commonly used to create a more uniform look on copper products, such as sculptures or jewelry. In some cases, a clear coat can be applied over the copper to speed up patination. Heating copper above 212 Fahrenheit (100 Celsius) will create a blue patina, while heating it to a higher temperature will create green and brownish patinas. Heating copper works faster than treating copper with a protective finish or chemical agents. Heating copper can also speed up the patination process of copper. It is best to use in dilute solutions as it can damage the copper if a concentration is too strong. Cupric Nitrate can be used as a fertilizer in garden patios or it can be applied directly to copper. The most common chemical used to speed up the patina process is cupric nitrate. Be sure to wear proper protective equipment when dealing with chemicals. Other methods of accelerating the patina of copper involve applying a mixture of chemical agents such as white vinegar and salt or ammonia and salt or a combination of the two to the copper. This prevents oxygen from reacting with the copper, which speeds up the patination process. One of the simplest methods is using a protective finish such as wax or lacquer. Accelerating the process of copper patina is possible in a variety of ways, depending on the desired result.
