Commodities And The Good Life

In a book review, the ever brilliant Matt Ridley narrates how commodities has contributed to economic progress and our good life.

An excerpt…

The discovery of the elements shadows and to some extent explains this evolving history of specialisation. The ancients knew of just seven metals: gold, silver, copper, tin, iron, lead and mercury. By giving each specialised roles, they improved their living standards—tin for hardening bronze, lead for moulding, silver for coinage and so on. By the modern era only one more metal—zinc—had joined them (although platinum was known to natives of the Americas). But then came a steady flow of new metals, each of which finds its particular role in technology and society: tungsten for hardness, aluminium for lightness, chrome for polish, neodymium for magnets, barium for medicine. Each finds its niche as surely as each profession and vocation does in human society. Just as our story is one of specialisation, so the story of chemistry is one of purification.

Each metal marches into our lives along a path from novel to banal, says Aldersey-Williams. Aluminium was once so difficult to make that Napoleon III used aluminium cutlery for only his most favoured guests and gave his son, the Prince Imperial, an aluminium rattle. Then it became so cheap that it was considered, well, cheap. Titanium, once rare and exotic, is becoming ubiquitous. For niobium and tantalum, Aldersey-Williams writes, “the journey is just beginning.” This is a tantalising thought. There are so many elements whose talents we have barely begun to use.
