在中国陶瓷发展史上,明清时期以江西景德镇为全国烧瓷中心的格局已经形成,景德镇出现了“官”窑“民”窑并存的大发展时期。“空白期”指明宣德以后的正统、景泰、天顺三朝(1436～1464年,以下简称三朝)的瓷器。由于没有发现其中任何一朝带官窑年款的瓷器存世,因而提出“空白期”的概念。 In the history of the development of Chinese ceramics, the pattern of Jingdezhen as the center of porcelain in the Ming and Qing Dynasties has been formed. Jingdezhen has witnessed a period of great development with the coexistence of “kilns” and “civilians”. “Blank period ” indicates the porcelain after Xuande orthodoxy, Jingtai, Tianshun three dynasties (1436 ~ 1464, hereinafter referred to as the Three Dynasties). Since no porcelain was found in any of its wares, the concept of a “blank period” was proposed.
