The Attraction Of A Verdigris Patina

By Amanda Bean


Metal with a verdigris patina has an aged beauty that is unique. This protective layer of oxidation is formed over metal like copper, brass and bronze through the years as it is exposed to the air. Products have been developed today that can speed up this natural process. These chemical solutions are able to add patinas to surfaces quickly and efficiently.

Metals like copper and brass were used frequently in the past to create a variety of objects, from pipes to garden statues. All these objects show signs of weathering after years that is hard to imitate. The popularity of this aged finish has lead to many faux painting techniques being devised to recreate the look, some of which are fairly successful. However, the true finish can only be obtained by the oxidation of metals.

Faux painting techniques allow individuals to recreate the effect of aging. However, the true finish is hard to imitate and is only produced when metals are oxidized. This chemical process is accelerated in several different ways. Using a source of heat, like a blowtorch, can create an interesting mix of blue and green patinas. Distilled vinegar or acetic acid produces a pretty green color as copper acetate is formed.

One of the attractions of a finish like this is that no two objects turn out exactly the same. The finish varies depending on different factors such as the type of metal and the techniques used to accelerate aging. The variations of tone and color provide a great foil to contemporary materials and give respect to days gone by.

The color of the patina depends on the type of metal and the length of time it has been exposed. Bronze often develops a blue-black color while copper usually produces a blue-green color. Various methods can be used to hasten the development of these colors, such as use of heat and vinegar.

Today there are many products that can speed up the process of creating genuine patinas. These are available at both local and online stores. They are easy to apply and clear instructions are given on usage. The surface has to be thoroughly cleaned before applying any of these products as even grease from fingers can affect the result.

Many different applicators can be used like brushes, sponges or even cotton wool. One can experiment with different methods of application too. Some individuals prefer to use many thin coats to build up the effect gradually and others apply a few thick layers.

Dipping the applicator directly into the bottle of product is not recommended. It is much better to pour out an amount into another disposable container for use. Other tips are to make sure that the surface is properly cleaned prior to treatment and to wash hands carefully after application.

A verdigris patina is a flattering finish for many objects, from candlesticks to garden statues. It allows one to add another element to decor accessories and fittings. The fact that products are available to create this effect without having to wait for years, makes it even more appealing.
