Royal Doulton Bone China Coffee Set with Wattle Design

• Bone China - Bone china, Also called 'English china", is one of the three types of porcelain, the other two being soft paste porcelain and hard paste porcelain.
  
  Porcelain is an ancient ceramic material, first made in China, hence the common name "china", and the introduction of bone china was to counter the imports of Chinese porcelain.
  
  The initial development of bone china is credited to Josiah Spode, who introduced it around 1800 and it was soon after copied by other manufacturers including Minton, Coalport, Davenport, Derby, Worcester, Wedgwood and Rockingham and the Herculaneum factory at Liverpool.
  
  Spode's bone china was made by mixing ash from cattle bones with feldspar and kaolin, which created a material that was stronger, more translucent, and whiter than traditional porcelain. He began to produce this new type of porcelain in 1796 and it quickly became very popular.
  
  At the time, the process and ingredients were kept secret and were only known to a few manufacturers and were protected by patents.
  
  In the 19th century, bone china became increasingly popular and was widely produced by many manufacturers in England. During this time, it was considered a luxury item and was often used to create fine dining sets and other decorative items.
  
  Bone china is still used in the production of fine porcelain wares, such as tea sets, figurines, and other decorative pieces. His basic formula of six parts bone ash, four parts china stone, and three and a half parts china clay remains the standard English body. It is still considered a luxury item due to its strength, translucency, and whiteness, and is often used for high-end and high-quality porcelain. China.
• Registered Numbers - Between 1842 and 1883, a diamond- shaped mark was used to identify items as British-made, which classified the item according to the material from which it was manufactured, as well as the date of registration. This system was discontinued in 1884 when a numbering system was introduced.
  
  Design registration is for "what and item looks like", and is not a patent ("how something works") or trade mark ("what it is called").
  
  The registered number is usually on an under-surface of an object (on the base of ceramics) and oftern shown as "Rd. No. 99999", sometimes surrounded by a rectangular box.
