Electric Blue Lustre Vase by William Moorcroft

• 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.
• Lustre Ware - Lustre decoration on ceramics is created by painting a thin deposit of metal oxide such as gold, silver or copper onto the surface, and then firing the item again, so that metal oxide forms a thin film on the surface. The finished effect is a shiny metallic surface. The technique was used in the 19th century by potteries such as Crown Devon, Grimwades, Maling, and Royal Doulton. However the best known use was by Wedgwood for its Fairyland lustre.
