Metals like copper and bronze form a protective layer over the years until they look quite different from their original bright color. The green color produced is called a verdigris patina. Today it is possible to create such a finish by using one of the many products on offer. These products have been created to produce the effect of oxidation on metals without needing years for it to develop.
One of the methods used in Medieval times to hasten the process involved burying wooden blocks with copper strips attached in dung for some time. Today, the burying technique is still used. However, nowadays objects are buried in absorbent materials like kitty litter or sawdust once they have been moistened with chemicals. Lovely textures and colors can be created in this way.
There were many other methods used in the past to hasten the oxidation process. Some involved placing copper plates in clay pots filled with distilled wine. Another method was to heat vinegar and hang the copper plates over the pot. The green crust formed was used by artists as pigment. All these processes still involved having to wait some time for a result.
It is much easier to create such a finish today. There are many products on the market devoted to this purpose. These products enable a chemical reaction to take place, accelerating oxidation and creating special results. One can never predict exactly what the finished article will look like as various factors affect the outcome and this adds to the appeal.
Applying these products is not difficult but some experimentation may be required to produce the result you are looking for. Some of the factors affecting the results are the chemicals used and the number of layers applied. The type of metal used also affects the color produced. A bluish green is common with copper and a bluish black with bronze.
Some products can be applied without any heat being used. The metal is coated a layer at a time until the required color is achieved. It is applied with a brush or a rag and some products can be sprayed on. If excess product is applied, it can become thick and chalky, flaking off easily. A tip is to use a small amount at a time, applying it from a disposable container.
Other products need heat for application and great care has to be taken as the chemicals used may be flammable. The benefit of applying heat is that the chemicals penetrate deeper. It is necessary to use gloves and other protective items. Toxic fumes can be given off so application should take place in a well ventilated area.
The popularity of this type of finish with designers, landscapers and homeowners means that many such products are available today from numerous outlets, including online stores. These products allow for a touch of rustic charm to be added to any object without having to wait for years. Countless different objects such as pots, statues, screens, doors and even jewelry can be given interesting textures and colors, adding to their allure.
