—Proof Of Salt “Instrumental analysis gives evidence for salt production in ancient China” ARCHAEOLOGY With the help of some high-tech analytical instruments, an international team has found "unequivocal proof" of salt production by early societies that flourished in central China during the first millennium B.C. According to the researchers, the finding is China's oldest confirmed example of pottery-based salt production and gives archaeologists new methods for evaluating other salt-producing sites (Proc. Natl. Acad. Sci. USA 2005, 102, 12618). To chemists, salt is simply an ionic crystalline solid. But to anthropologists, salt is the hallmark of a complex society.
