Export and smuggling of Spanish platina in the eighteenth century

The European demand for platina in the late eighteenth and early nineteenth centuries could not be met by the Spanish authorities who only authorized limited exports of the mineral, approximately 267 kg between 1750 and 1804. The lack of an adequate commercial structure generated direct trade between Latin America and Europe, particularly England. This article is an attempt to analyse and to quantify the three European sources of platina: exports from Spain, shipments of platina consigned by European travellers, and direct trade. The reasons for the latter are studied, exemplified by the Wollaston case, and legal and direct trade are compared.
