Antique Brass – Care, Preservation And Restoration Tips
Antique brass is a beautiful material that is often left un-restored because it lends a deep, rich color and tone to old objects. The antiquing occurs when oxygen reacts with moisture and other elements in the air to tarnish the surface of the metal. While some prefer the look of polished metal, the patina and wear of antique brass is actually more valuable when it is intact because polishing literally rubs away layers of the original metal, which can potentially damage it and weaken it. Therefore, if you own any antiques, it is important to know how to care for old brass and keep it in the best condition possible.
In optimal conditions, brass will begin to patina within a few years of being finished, and will gracefully age for hundreds of years until the brass is antiqued. The optimal conditions for brass to properly age are mild temperatures and moderate humidity in non-coastal areas. The salt and humidity in the air in coastal cities can deteriorate brass as such a rapid rate that it can fall apart within just a few years. This is one of the reasons that antique brass items found in ancient cities near coastal regions are as fragile as dust balls, while brass that has aged properly in drier regions retains its structural integrity while still achieving the beautiful rich brown and red color that so many antique collectors have come to love and appreciate.
Caring For Antique Brass
Cleaning and conditioning antique brass improperly can destroy it, especially when you want to retain the natural beauty of this material. There are many chemical agents on the market which are specifically marketed to keep old brass in prime condition, but they really don’t stand up to the challenge. Caring for antique brass is a simple and delicate process which doesn’t require any harsh chemical additives or treatments.
To clean antique brass, you should only use warm, soapy water and a microfiber cloth to remove surface dust and grease. Elbow grease is not required, because even the slightest bit of friction between the fibers in the rag and the brass can scratch away surface patina, which will allow oxygenation to occur at deeper levels in the brass. Once tarnish is allowed to reach deeper in the brass, the antique can crumble away. Do not use regular wash cloths, brushes or paper towels, as they are too abrasive to gently remove surface grit.
Preserving Antique Brass
To lock in the patina and condition your antique brass items, you can gently apply olive oil or linseed oil to your brass with a microfiber rag. Brass sealants that are sold at hardware stores work great for new brass, but when you are dealing with brass that is more than a couple of decades old, it is important to use the most gentle methods possible or you will risk destroying the antique finish on the brass. Olive oil will penetrate microscopic pores in the brass, keeping oxygen and moisture from reaching inner layers of the material. Linseed oil works the same way, but is a bit more aggressive and expensive, and is often used to treat steel tools. Olive oil has been used for thousands of years, dating back to at least ancient Rome, to preserve brass from wear.
