Keith Murray Wedgwood Brown Basalt Porcelain Vase with Ribbing

• Basalt - Basalt is a hard, dense volcanic rock formed from the rapid cooling of basaltic lava, and makes up most of the earth's oceanic crust.
  
  However it is also the name given by Josiah Wedgwood in 1768 to a fine black unglazed porcelain which he called Wedgwood Black Basalt.
  
  Using this fine-grained stoneware he was able to produce copies of the newly excavated Etruscan pottery from Italy, with a lustrous and smooth, surface, and this new innovation proved to be a huge commercial success.
• 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.
