Philip Marsden: Under A Metal Sky

My guest in this week’s Book Club podcast is Philip Marsden, whose new book Under A Metal Sky: A Journey Through Minerals, Greed and Wonder looks in thrilling and surprising detail at the wonders that are to be found beneath our feet. On the podcast he takes me through the meanings that rocks and metals have had through human history, from the bronze age, via the alchemist’s quest for the philosopher’s stone, to the present day.
