Carved lacquer or Qidiao is a distinctive Chinese form of decorated lacquerware. While lacquer has been used in China for at least 3,000 years, the technique of carving into very thick coatings of it appears to have been developed in the 12th century CE. It is extremely time-consuming to produce, and has always been a luxury product, essentially restricted to China, though imitated in Japanese lacquer in somewhat different styles. The producing process is called Diaoqi.
