Extreme Case of Tarnish

We've discussed in several articles the effects of sulphur on sterling flatware resulting in tarnish. Here's an interesting case regarding more serious tarnish.

In the news media recently, there have been many reports regarding a problem with drywall material manufactured in China. It seems that the drywall emits a gas containing sulphur. Copper pipes and appliance components containing copper are being affected.

The web site, Chinese Drywall Complaint Center, contains information about the problem. We have no idea who actually manages the web site but the information seems reasonable.
