Mercury is a relatively rare metal, whose use has long been
irreplaceable in a variety of technical, chemical and industrial
processes. It has only been produced in substantial quantities and over a
long period by a small number of mines worldwide, of which the two
largest, until recent times, were at Almadén in Spain and Idrija in
Slovenia. These two mining towns, whose origins date from ancient or
Medieval times, demonstrate the lengthy period over which a
socio-technical system of extraction specific to this metal was in
operation, and the process of evolution it underwent.
Many thanks to Mirjam who contributed to my collection, also using lovely bird stamps :))
