Double Ended Silver Spirit Cup by Graham Watling, 1977

• 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.
• Modernism / Modernist - Modernist furniture and design emerged in the early to mid-20th century as a response to traditional styles of the 19th century and prior times, and a reflection of the technological and social changes of the time. Characteristics of Modernist furniture and design include simplicity and minimalism and clean lines and a lack of unnecessary ornamentation are key features. That form follows function is a fundamental principle of Modernist design, and furniture and objects are designed with a focus on their practical use.
  
  Modernist furniture often incorporates geometric shapes, such as cubes, rectangles, and circles. This reflects a departure from the more ornate and curvilinear forms of previous design styles. The furniture often prioritizes ergonomic design, ensuring that objects are comfortable and user-friendly. Modernist designers aimed to create designs that could be mass-produced, making good design accessible to a broader population.
  
  Prominent figures associated with Modernist furniture and object design include designers such as Hans Wegner, Verner Panton, Florence Knoll, Harry Bertoia and Ettore Sottsass
• 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.
