Chinese Cloisonne Covered Box with Qianlong Mark

• Crackles / Cracquelure - In ceramics, crackles may be introduced intentionally during the firing process, as was often the case with Oriental ceramics, and are known as artificial crackles. Natural crackles occur with age, and if the glaze is transparent, may be difficult to detect. Natural crackles may not cover the whole surface of the object and may be uneven in size.
• 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.
• Crackling and Crackle as a Decorative Technique - Crackle, also known as crackling, is a decorative technique that has been used in China for centuries. It is believed to have originated during the Song Dynasty (960?1279 AD) and was primarily used in the production of ceramics, lacquerware, and furniture. The crackling effect was achieved by applying a glaze or lacquer that was formulated to crack during firing, creating a crackled pattern on the surface of the item.
  
  During the Ming Dynasty (1368?1644 AD), crackle became a highly sought-after decorative technique, and it was used to create intricate and beautiful designs on ceramics and lacquer ware.
  
  In Western decorative arts, crackle / crackling came into use during the Art Nouveau movement in the late 19th and early 20th century. The crackling effect was used to create a sense of movement and fluidity in the design of Art Nouveau pieces.
  
  It was also used in the 1920s and 1930s during the Art Deco movement.
