Those natures which, when they meet, quickly lay hold on and mutually
affect one another we call affined. This affinity is sufficiently striking in the
case of alkalis and acids which, although they are mutually antithetical … most
decidedly seek and embrace one another, modify one another, and together
form a new substance … It is in just this way that truly meaningful
friendships can arise among human beings: for antithetical qualities make
possible a closer and more intimate union.
Goethe, Elective affinities (1809)
A linear mode of historical understanding relegated alchemy to a ‘pre-scientific’ era, with the enlightenment's New Chemistry creating a break between
‘empirical’ and ‘scientific’ metallurgies. Similarly, Bolivia's early Republican
silver-production has been regarded as ‘stagnant’ and ‘colonial’ from the
‘modern’ perspective of late nineteenth century liberalism. This article questions
both periodisations by documenting an ‘alchemical renaissance’ in Bolivian
silver-refining methods during the first part of the 19th century. The relaunch of
Alonso Barba's ‘hot method’ of amalgamation in copper cauldrons (1609), and
its associated technical discourses, expressed a creole desire for an independent
‘modernity’. This rediscovery of a seventeenth century technology, carried out
shortly before the Independence War in the Potosí provinces (Chichas), and
slightly later in Oruro and Carangas, is distinguished from the version reinvented
in Central Europe by Ignaz von Born (1786), as well as from two pre-Bornian
experiments in Potosí and New Spain. Its nineteenth century consolidation was,
in part, a little-known reaction to Nordenflicht's failure to introduce the new
European method of rotating barrels to the Andes during the 1790s. The article
shows that this ‘alchemy of modernity’ held its ground for several decades,
suggesting a fresh approach to America's postcolonial ambiguities from the
perspective of a comparative history of technology.
