Wedgwood Blue Lion Vase by Erling Olsen, 1932

• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Dating English Ceramics - Excellent detailed reference books such as Godden's Encyclopaedia of British Pottery and Porcelain Marks will help to identify and date specific manufacturer's marks.
  
  However, there are a few simple guidelines which may also help.
  
  The inclusion of the word 'England' on an item ensured compliance with the American McKinley Tariff Act 1891, which was important for British exporters. An item so marked would have been made after 1891.
  
  In 1921 the act was revised to require the phrase 'Made in' followed by the country. So if an item is marked 'Made in England', it is generally considered to be made after that date, although some manufacturers were using this phrase pior to the act being changed.
  
  The use of the word 'Ltd' of 'Limited' after a company's name indicates a date after 1860, though with ceramic manufacturers this did not become general practice until the 1880's.
• Earthenware - A basic ceramic material that is fired at a low temperature. Earthenware is the basis of almost all ancient, medieval, Middle Eastern and European painted ceramics. After firing, the colour is the colour of the clay when it is dug from the ground: buff, brown and red. It is not waterproof until glazed. Creamware is a type of earthenware covered with a transparent lead glaze. Majolica, faience and delft are also earthenware covered in an opaque white tin glaze.
