Ward off the flu with copper?
Flu season continues, so it's perhaps of interest to consider that copper and copper alloys, such as brass, have been promoted as antimicrobial materials. This property has gotten the attention of some hospitals, in fact, where there has been use of copper for countertops, door handles and other fixtures as a way of minimizing the spread of infection. However, the antibacterial effects of the metals have been shown to be negated, particularly when the materials come into contact with human perspiration, which then causes a layer of oxide that can corrode the protective nature of the metal.
Regardless of the accuracy of such claims, base metal makes for a beautiful focal material for decor and accessories. As for jewelry, base metal, like copper, offers a more affordable way to wear interesting, handcrafted jewelry compared to the much more expensive platinum, gold and silver metals. With a little care from a polishing cloth and/or protective polish, copper, brass, and bronze jewelry can look as good as the moment purchased for years to come.
