Blue Masons Ironstone Jug with Butterfly Enamel Painting

• Ironstone China - Credit for the invention of ironstone china is generally accorded to Charles Mason in 1813. Charles Mason was one of the two sons of Miles Mason who founded the Mason works in 1802, and ran the business with his brother George Mason.
  
  Ironstone was a heavy hard earthenware which was slightly translucent, its strength supposedly coming from a very small quantity of iron slag added to the mixture. The additional strength enabled the company to make larger objects that were not susceptible to breakage.
  
  The company manufactured dinner wares, toilet sets, tureens, jugs and so on, and the most popular patterns were blue and white, floral and Oriental Imari style colours.
  
  The trade name "Patent Ironstone China" was registered by the company in 1813, but the patent was only valid for 14 years and was not renewed, enabling other potteries to use the word "ironstone" in describing their wares.
  
  Mason wares are generally well marked with "Mason's Patent Ironstone China" .
• Mazarin Blue - Mazarin blue, also known as bleu de Mazarin, is a shade of blue named after Cardinal Mazarin, a prominent French statesman and Catholic cardinal who lived in the 17th century. The color is a deep, rich blue with a hint of purple, and it was popular in France during the Baroque period.
• Georgian - As an English stylistic period, Georgian is usually taken to cover the period from George I (1714) to the Regency of Prince George (1811-20), although the period from 1800 to 1830 is sometimes designated as the Regency period. During the Georgian period the great English cabinetmakers and designers such as Chippendale, Hepplewhite, Adam Sheraton etc., were all active.
  
  Therefore there isn't a single 'Georgian style' as such and to say something is 'Georgian', usually means it was made between 1714 and 1830. This assumes we discount George V and George VI, both being from the 20th century.
  
  The styles popular at the time of each reign were:
  
  George I (1714-1727) saw out the last years of the Baroque period.
  
  George II (1727-1760) reigned during the Rococo period.
  
  George III (1760-1820) saw the last gasp of the Rococo, all of the early Neo-Classic 'Adam style' and most of the later neo-Classic 'Regency style'.
  
  George IV (Prince Regent 1820-1830)encompassed the last of the 'Regency' style.
  
  William IV's reign (1830-1837) was something of a no man's land (stylistically) and he wasn't a 'George' anyway. He covered the last glimmerings of 'Regency' and the start of the 'Victorian' style.
