Copper Metal from Malachite circa 4000 B.C.E.  Gordon T. Yee, Jeannine E. Eddleton, and Cris E. Johnson
The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores. Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction. The product is a shiny copper metal bead that can then be hammered, polished, and shown to be electrically conductive.
