Mineral commodities: more information
To go straight to the source—where I get the figures that let me say we import this much of that mineral from China or wherever—visit the USGS Mineral Commodities Summaries pages. The data there serve as starting points for What Things Are Made Of. Then I explore questions like “Why does China have such large rare-earth deposits?” or “How did Missouri’s lead ore form?” and “What was the connection between the alum trade and the Pazzi Conspiracy in Renaissance Italy?”
My goal with What Things Are Made Of is to connect the chromium in your stainless-steel fork to its geological origins, its role in history, and its place in a complex, global network of interdependent producers and consumers. And to try to do that for hundreds of things around us every day.
