| Copper is reactive - and depending on the acidity of the environment will turn the familiar dark brown of an old penny or the bright green you can see in roofs and gutters sometimes. As the metal reacts it can slough off bits of material, although that's in the most extreme cases like an urban rooftop exposed to acid rain... At any rate, I agree with Caitlin that copper wouldn't be the best material to touch the pearls. It's a great excuse to find a nice piece of silk. |
