The slightly matte, silkytianbai glaze was developed by potters working at the imperial kilns in Jingdezhen under the Yongle emperor in response to the his preference for fine white porcelain wares to be used in the palace and ritual ceremonies. This type of glaze was later known as 'tianbai', a term that was first used by the Ming writer Huang Yizheng in hisShiwu Ganzhu, who accurately described the glaze as 'white like congealed fat, immaculate like piled-up snow', seeImperial Porcelain of the Yongle and Xuande Periods excavated from the Site of the Ming Imperial Factory at Jingdezhen, Hong Kong, 1989, p.71. Producing this unctuous, silky glaze on a pure white, fine porcelain body presented a technical challenge for early Ming potters as the large numbers oftianbai sherds unearthed in Jingdezhen from consecutive Yongle strata demonstrateop.cit., p.19.Today, few early Ming 'sweet-white'-glazed porcelains survive. A jar of closely related form, incised with dragons instead of scrolling lotus under a 'sweet white' glaze, was excavated from the site of the Ming imperial kilns at Jingdezhen and dated to the Yongle period, is illustrated inYuan and Ming Imperial Porcelains Unearthed from Jingdezhen, Beijing, 1999, p.146, no.95.pare also with a larger jar covered with atianbai glaze, formerly in the Collection of y & Co., sold Christie's New York, 23 March 2023, lot 895, and another larger jar in the collection of the Nanjing Museum, published by Xu Huping inThe Treasures of the Nanjing Museum, Hong Kong, 2001, p.56, no.39.
