A patina is the layer that forms naturally on metals such as copper and bronze when exposed to air over a long period of time. This oxidation actually changes the color of the metal. People like these changes in color so much that they have devised all kinds of ways to hasten the process. Patina jewelry is created by using chemicals to accelerate oxidation. Many products created in this way are available from online stores today.
The process is still an organic one, even if chemicals are used, and no two finishes are exactly the same. Variations in color occur according to the types of chemicals and techniques used. Copper, for example, can vary in color from a warm, light brown to a deep burnt umber. It may even acquire a green finish, like the verdigris effect seen on an old statue in a park.
Warm brown, red, blue, green-blue, black and many other colors can be created depending on which processes and chemicals are used. Silver turns to black or gray when a liver of Sulfur is used but yellow, reddish brown, blue and purple colors are also possible by using different strengths of the mixture. Household chemicals like vinegar and ammonia can also be used and vinegar turns copper green while ammonia turns it blue.
There are many different methods used by designers to hasten the oxidization process. Immersion, spraying, painting and heating are just some of the ways used to create these effects. A method used in the Middle Ages was to bury copper in dung to hasten the color change. The method of burying is still used today but items are now buried in sawdust, sand, coffee, cotton wool and many other mediums which are saturated with a particular solution.
Experimentation is often required to learn how to achieve a particular effect. The result is one-of-a-kind items with great character as even the designer does not always know what effect is going to be obtained. Ready-made chemical solutions are available too that offer effective, tried and tested results.
A wide variety of different items are created by designers today, combining unique finishes and artisan shapes. Upscale organic looking items are created such as a pair of brass butterfly earrings with even the ear wires are made of oxidized sterling silver. A pair of simple golden, brass birds sitting on silvery flowers are set off with a teal colored brass chain. Necklaces come in all sorts of styles, from an olive green three layer leaf necklace to a a turquoise cross pendant on a copper chain.
One important factor to consider when purchasing such products is the way in which they have been finished. The fact that the colors are created by the process of oxidation means that they are unstable. They continue to oxidize over time when exposed to air and this means that the color can change. Proper sealing is required in order to stop this from happening.
Patinas are effective in changing the look of items altogether. Jewelry is often given a whole new character by adding this dimension. Purchasing these items online offers access to a wide variety of styles and colors. As long as a reputable supplier is selected, this way of shopping can save time and money.
