Emerald Green Chinese Porcelain Vases with Bird Design

• 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.
• 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.
• 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.
