1816 London Sterling Silver Mustard Spoon by Thomas Barker

• Hallmarks - A mark stamped on articles of precious metals in Britain, since the 14th century, certifying their purity. It derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay (test the purity) and mark articles of gold and silver.
  
  The hallmark will consist of several marks, including the:
  
  - silver standard mark, indicating the purity of the metal. Sterling silver is .925 pure silver.
  
  - the city mark indicating the city in which it was assayed eg London, Birmingham, York etc.
  
  - the date mark, usually a letter of the alphabet in a particular font and case,
  
  - a duty mark, indicating whether duty had been paid to the crown, and only in use from 1784 to 1890
  
  The piece may include an additional mark, the maker's mark, although not forming part of the hallmark, will be located in the vicinity of the hallmarks.
  
  Sometimes silver plated items will bear faux hallmarks, often confusing those not familiar with silver markings.
• Marrow Spoon - A spoon with a long handle and a narrow scoop shaped bowl, used to scoop and eat marrow from the hollow centre of roasted bones. Some marrow scoops are double ended with a different shaped bowl at each end.
• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
• Oviform /ovoid - The outline loosely resembling the shape of an egg.
• Fiddleback - A name given to the pattern of the grain in some timbers, where the lines of the grain are compressed and at the same time wavy. Fiddleback grain is prized as a timber for furniture and musical instruments, and is expensive becasue of its scarcity.
  
  In Australia fiddleback graining is found in blackwood. Other non-native timbers that are sometimes found with a fiddleback grain are mahogany and maple.
