Copper Green Brass

The Copper Green Brass finish developed by Lamberti Design is inspired by the natural patina that covers the famous Statue of Liberty. This is the result of the long exposure (more than a century) of copper to the weather conditions (rain, sunlight, pollutants) creating the well-known green coloration. The greenish color is a mix of copper salts including acetate, sulfate and carbonate. Brass is a copper-zinc alloy; it shows a good resistance to corrosion, and is able to form different types of oxides, which tend to darken over time. Lamberti Design developed an accelerated oxidation process that reduces  the patina formation time to a few days. The Copper Green finish can have slight color variations from yellow to pink, that could darken over time. Mechanical and chemical cleaning steps can significantly influence the final quality surface. In addition, the preparation itself can speed up and “standardize” the quality of the final products. At the end, a protective clear coat is applied. This finish is for indoor applications. If applied outdoor the exposure to the atmospheric agents could cause chromatic variations and oxidation. The environmental conditions, the geometry and the shape of the products, combined with the artisanal processes, make the final pieces unique; in fact, any chromatic variations on the final objects compared to photos and samples received, are intrinsic characteristics of the process and not manufacturing defects.

Care and cleaning instructions of metals
Liquids can stain any metal surfaces, therefore we recommend cleaning with a soft slightly damp cloth with neutral soapsuds, and then following using a soft, dry cloth. Do not use abrasive materials, aggressive detergents, acetone, solvents and alcohol to clean metal surfaces.
