Art Nouveau Kelmscot Jug, Doulton Burslem, 1902

• 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.
  
  The table below lists the year, and the first registered number for that year:

• Art Nouveau Period - The Art Nouveau period was a cultural movement that emerged in the late 19th century, and was characterized by its emphasis on natural forms, flowing lines, and a decorative, ornamental style. Art Nouveau was a reaction against the ornate and heavily stylized designs of the previous era, and sought to create a new, more organic aesthetic.
  
  Art Nouveau was characterized by its use of sinuous, curving lines, as well as a focus on natural elements such as flowers, vines, and other organic shapes. Art Nouveau designers sought to create a total work of art, in which every element of a building or object was designed to be harmonious with the overall design.
  
  Some of the most iconic examples of Art Nouveau design include the Paris Metro entrances designed by Hector Guimard, the works of the artist Alphonse Mucha, and the architecture of Victor Horta in Brussels.
  
  The Art Nouveau period was at its peak between 1890 and 1910, but began to decline in popularity by the start of World War I. However, Art Nouveau remains an important influence on design and art to this day, and continues to be celebrated for its emphasis on natural forms and decorative style.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
