Was your home all decked out for the holidays? As you gazed at your glowing trimmings, you might have paused to wonder what gave your delightful décor some of its traditional seasonal color: cobalt oxide, cadmium sulfide and sulfur. According to USGS scientists who collect worldwide data on almost all mineral resources, holiday lights are made with these and other minerals from around the world. The world’s supply of minerals — such as salt, manganese and lime — lights up the holiday season, helping many nations and cultures to celebrate their long-time traditions. In 2007, the mineral materials processed domestically accounted for more than $575 billion in the U.S. economy.
