Dictionary of Traded Goods 1550-1820 now online

I've been having great fun using the University of Wolverhampton's Dictionary of Traded Goods 1550-1820, 'a dictionary of nearly 4,000 terms found used in documents relating to trade and retail in early modern Britain', to find out about the trade in pigments. The Dictionary tells you about the pigments, their properties and origins and trade, and what prices they might fetch, and how they were described (eg. different weights, variations and combinations, and so on) and advertised. It's available through British History Online, a wonderful resource hosted by the Institute for Historical Research.
