Moorcroft 'Columbine' Plate, Crazing and Hairline Crack

• Crazing - A network of fine cracks in the glaze of a ceramic item, caused by uneven shrinking during the firing process.
• Firing Crack - A firing crack is a crack in a porcelain or stoneware item that occurs whilst the item is in the kiln.They are usually caused by faulty design, where one part is thicker than the surrounding area, and being thicker it cools more slowly, setting up a stress with the surrounding area. Firing cracks are not often seen on modern mass produced porcelain, as the damaged items are discarded during prooduction. However they are seen in earlier items and artisan-produced objects.
• 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.
