19th Century Sheffield Plate Teapot with Griffin Coat of Arms

• Griffin / Griffon / Gryphon - A griffin, also known as a griffon or gryphon, is a mythical creature with the body of a lion and the head of an eagle. It is typically depicted as a powerful and majestic beast, with the body and legs of a lion and the head, wings, and talons of an eagle. The griffin is widely recognized as a symbol of strength, courage, and guardianship, and has been used in a variety of cultures throughout history.
  
  In ancient mythology, the griffin was often associated with the gods and was considered a symbol of divine power. In ancient Greece, for example, the griffin was associated with the sun god Helios, while in ancient Egypt, it was associated with the goddess Hathor. In medieval European heraldry, the griffin was used as a symbol of strength, valour, and protection, and was often featured on the coats of arms of noble families.
• 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.
