Not diamonds or gold...rock, the raw material of  civilization! Without rock, modern society wouldn't exist.  Roads, sewers, dams, bridges, buildings, paint, glue,  make-up, antacids, and even chewing gum need crushed stone.  From ancient days to the present, we explore the evolution  of quarrying techniques.},
