Peachbloom-glazed wares rank amongst the most admired of Kangxi porcelainS. The present seal paste box, also known as yinse he or 'vermilion box', belongs to one of eight peachbloom-glazed wares made for the scholar's table. The glaze, also known in Chinese as 'apple red,' 'bean red', or 'drunken beauty,' required the utmost technical precision. To create this effect, a copper-lime pigment was blown through a bamboo tube onto a layer of clear glaze and then covered with another layer of clear glaze. This resulted in the variegated pink and occasional green tones, depending on the firing conditions. 

Similar seal boxes can be found in the Metropolitan Museum of Art, New York, illustrated in Suzanne G. Valenstein, A Handbook of Chinese Ceramics, New York, 1989, fig. 237; in the Palace Museum, Beijing, published in Kangxi. Yongzheng. Qianlong. Qing Porcelain from the Palace Museum, Hong Kong, 1989, pl. 124; and in the National Palace Museum, Taipei, included in the museum's Special Exhibition of K'ang-hsi, Yung-cheng and Ch'ien-lung Porcelain Ware from the Ch'ing Dynasty, Taipei, 1986, cat. no. 11.
