‘The Discrete Charm of Platinum’
Dr Mariana Sanchez-Daza (Université Paris Diderot) and Dr John Christie (University of Oxford)
This talk will analyze temporal aspects of the material platinum, beginning briefly with the astrophysical processes which originate it and the astronomical and geophysical processes which have embedded it in planet Earth, then proceeding to the historical temporalities within which platinum became a subject of human cognizance, enquiry and use
After a résumé of archaeological evidence indicative of early human uses of platinum, our emphasis will be upon the history of scientific discovery, experimental enquiry and manufacturing development, and the economic and political histories of empire with which platinum became, and remains, deeply entangled. Although platinum received increasing experimental attention from chemists in the eighteenth century, it remained for the most part a refractory material, resistant to reactivity and to fusion, and only in the early decades of the nineteenth century was it rendered amenable to processes usable for large scale production. Platinum’s imperial entanglements began to take form in the middle decades of the eighteenth century, focused first upon the Hispanic empire, then later, in the nineteenth and twentieth centuries, upon the British, leaving a post-imperial aftermath still active today.
