Learn about Sheffield Plate
Sheffield Plate was the first commercially viable method of plating metal with silver. The method of plating was invented by Thomas Boulsover, a Sheffield Cutler, in 1743 and involved sandwiching an ingot of copper between two plates of silver, tightly binding it with wire, heating it in a furnace and then milling it out in to sheet, from which objects could be made.
Originally used by its inventor to make buttons, the potential of the material was quickly realised, and soon it was being used to fashion boxes, salvers and jugs, and not long after that candlesticks and coffee pots, and other traditional tableware.
Although there was a considerable saving in the amount of silver used, Old Sheffield Plate manufacture was more labour intensive than solid silver, meaning higher labour costs. This meant that Old Sheffield Plate was very much a luxury product, and only available to the very wealthy.
The thickness of the silver means that many 18th century Sheffield Plate pieces still have a good layer of silver, while electroplated pieces (EPNS), may have been replated several times over their lifetime. more...
