Grinding a compound to create a new one dates back to at least 315 B.C. That’s when Aristotle’s student Theophrastus of Eresus wrote about the reduction of cinnabar—mercury(II) sulfide—to elemental mercury by grinding it with a copper mortar and pestle, according to Laszlo Takacs, a physics professor at the University of Maryland, Baltimore County, and an expert on the history of mechanochemistry. Scientific publications from the 1880s to the early 1900s indicate . . .
