When it comes to patina chemicals, you really want to pay attention to the blue-black patina chemicals, which are the most desirable. These chemicals have a gorgeous metallic luster and should never scratch or dull copper. If you do decide to use these chemicals in an electroplating process, make sure you use them very slowly so they can fully develop. Copper is one of the hardest alloys to plate, so using these chemicals too quickly can cause an excessive amount of heat to build up, which can destroy the plate. This heat should only remain for a short period of time, as excess heat tends to lead to distortion.
Metallic pigments are the easiest types of chemicals to work with. They simply need to be mixed with a carrier oil and applied with a brush or sponge. There’s no need for further processing and most patina patterns can be achieved quickly with this type of application. Metallic colors tend to be the most permanent, so they’re the best choice for body artwork.
Organic patina is achieved by mixing inks and dyes with oils. Organic patina looks similar to a metallic finish because the pigments combine with the oils present in the metals to create a color that blends in with the natural world. The patina of organic metals last longer and they can even be polished to give them a shiny look. They’re less durable than metals, but they’re the best choice for a jewelry item that’s more likely to get worn. When worn regularly, the patina will reveal an unmatched beauty that only the material can bring.
Copper patina is created from a variety of chemicals including zinc, tin, aluminum and iron. These chemicals interact with one another creating unique patterns on the surface of the metal. There are four primary types of patina: copper, brass, bronze and iron. In addition to creating a surface with greater color and texture, patina also enhances the durability of an article.
Copper is one of the most desirable metals to have a patina, because it has both a soft and a tough feel. This makes copper very practical for making tools, gears, decorations, and other metalworking implements. Metal working with copper is done by dipping brass or bronze wires in an acid, which is then painted with gold or silver colors. After this patina process, the metals will be much more responsive to the touch and will corrode much less easily than other metals.
There are a variety of patinas to choose from. The most sought after patina process is called ‘bondering’ and it involves applying very thin layers of copper along with silver or gold colored metals to create a patina that mimics the texture, weight, and appearance of brass or bronze. This process requires an expert craftsmanship as well as the skill to remove the different layers of metal to reveal a completely new patina each time you do so. You may choose to experiment with the different patina processes to find one that you like best, but remember that it will take at least a few days of work for the entire patina process to create a desirable result. Once you have chosen the method you want to use, read the instructions carefully and make sure you understand everything that is included in the kit before you begin.
If you are using copper as a material for your patina then you will need to apply a clear lacquer to the surface. When applying the lacquer you will need to apply it from the bottom of the surface, which will be the same side as the metal it is protecting. Make sure that it is applied adequately to create a smooth and uniform layer. When finished with the coat of lacquer you can always scrape it off with a knife and then re-apply the lacquer to the metal. You will be left with a protective coating that will not allow sunlight to penetrate into your car.
