How did Sheffield Plate change silver production in Britain?

Sheffield Plate began around 1743 through the work of Thomas Boulsover, who discovered how to fuse silver and copper into a single sheet. This allowed manufacturers to create items that looked like solid silver at a lower cost. Production expanded rapidly between 1750 and 1820, with thousands of items made each year. Popular goods included candlesticks, trays, and teapots. The process required skilled labour, as the bonded metal had to be shaped without separating the layers. By the early 19th century, Sheffield Plate was exported across Europe and North America. The technique declined after electroplating appeared in the 1840s, which allowed a thinner silver coating and faster production. Surviving Sheffield Plate items are now collected as antiques. Well-preserved examples, especially those with minimal wear, can sell for several hundred euros. The method played a major role in making silver-style goods available to a wider public during the Georgian period.
