This era witnessed a turbulent time and economic decline of the Ming Dynasty due to the frequent wars and court conflicts. And the emperors also shifted their interests to other fields. The royal kilns therefore stepped down to a stagnation period with shrinking output, which was also called a "blank period." It is said that the Emperor Jingtai was very fond of Cloisonné and ever ordered to replace all the court's porcelains to Cloisonné, but until now there is no discovery of the royal products with clear chronological inscriptions. However, the porcelain remains excavated in the site of royal kilns in Jingdezhen during the blank period show elegant forms and sophisticated techniques in the blank period.
