Moorcroft Banksia Vase, Sally Tuffin Design, 1987

• Oviform /ovoid - The outline loosely resembling the shape of an egg.
• Tubelined - In tubelined decoration, a thin line of clay is piped on to the surface of the object through a nozzle to define the design outlines, then the glazes are poured into the areas of the object that are created behind the shallow "dams" formed by the tube-lined decoration.
  
  Tubelined decoration was extensively used by Moorcroft Pottery. It was an expensive decorating technique, owing to the many possibilities of error in manufacture.
• 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.
• Emeralds - Emeralds have been used in jewellery making for thousands of years, and are prized for their deep green colour, which is caused by the presence of chromium and vanadium in the mineral beryl. Because of their rare colour, emeralds are often more valuable than diamonds of a similar size and quality. In jewellery making, emeralds are typically cut into round or oval shapes to maximize their color and clarity. They are often set in gold or platinum and used as the centrepiece of a piece of jewellery, such as a ring or necklace. They can also be used in combination with other gems, such as diamonds, to create intricate and beautiful designs.
