George III Sheffield Plate Salts by W&G Sisson//Robert Cadman

• 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. Where the silver has worn off the Sheffield plate the soft glow of the copper base can be seen underneath. However this is not an infallible guide that the piece is Sheffield Plate, as many EPNS items were also plated on to a copper base.
  
  Most Sheffield plate items are unmarked, whereas most elecroplated items display manufacturers names or marks, quality indications such as "A1", "EP", together with pattern or model numbers.
  
  Sheffield plate was made commercially between 1750 and 1850.
• Scallop / Shell Motif - The shell motif has been used in furniture and decorative arts for centuries. In ancient Greece and Rome, shells were often used as decorative elements on furniture and in mosaics. The scallop or cockleshell are the most commonly used. During the Renaissance, the shell motif became popular in furniture and architecture, as the ornate decoration was seen as a symbol of wealth and luxury. In the 18th century, the Rococo style of furniture and decorative arts featured an abundance of shell motifs, and it was used by Thomas Chippendale and as a feature on Queen Anne style cabriole legs. In the 19th century, the shell motif was incorporated into Victorian furniture and decorative items, and often a representation of the the conch shell was inlaid into furniture.
