Gems and the Crafts in the Chemical Revolution
Michael Bycroft
Chemistry is inseparable from the chemical crafts. This is a commonplace in the historiography of chemistry. But what about the relationship between the crafts themselves? How were chemical ideas shaped by the interaction between different arts, trades and industries? I answer this question with respect to gemstones in European chemistry in the latter part of the eighteenth century. In this period, and not before, chemists found general procedures for dividing gems into their component substances. Miners, apothecaries, glass-makers, and porcelain-makers were all involved in this process, as well as jewellers and diamond-cutters. These interactions between crafts were not just a matter of generalization or juxtaposition. New kinds of analysis emerged when two or more crafts interacted. Chemistry was greater than the sum of its crafts.
