Three Chinese Blue and White Reticulated Vases

Reticulated porcelain, is characterised by intricate cuts creating a pierced pattern. Père Francois Xavier d`Entrecolles (1664-1741) used the term reticulated in the 18th century to describe porcelain that had the appearance of a net. An alternative term for this type of porcelain is 'Devils Work', or Guigong. The Chinese term 'Linglong' is also used, which refers to something that is exquisite and elegant.
The Kangxi period was known as the 'age of innovation'. Reticulated decoration was combined with other innovations of the era. Examples of double-walled reticulated porcelain from this time, such as double-walled reticulated bowls and teapots are known but vases are more rare.  A rare double-walled reticulated hookah base was held at Schloss Trachenberg, Silesia.
 Openwork patterns can be found as early as the Shang Dynasty, where it appears on bronze wares, which are in some instances double-walled, with a closed inner and pierced outer wall.
In porcelain The National Palace Museum, Taipei, holds three related reticulated vases. The ceramic vessels have pierced walls, and an inner closed hull so they could be used.  These were made  by the official (guan) kilns of Laohudong in the Song dynasty (960-1279), see, (Du Zhengxian, ed., Hangzhou Laohudong yaozhi ciqi jingxuan [Selection of porcelains from the Laohudong kiln sites in Hangzhou], Beijing, 2002, pls 24 and 25).
In the Ming we find double-walled work in favour on fahua ware see one illustrated in: Idemitsu Bijutsukan zhin zuroku. Chugoku toji / Chinese Ceramics in the Idemitsu Collection, Vol. 3, Tokyo, 1987, no. 683.
This innovation and technical sophistication continued into the Qing period, in the Kangxi period with objects like our vases and then incredibly intricate Imperial vases were made for the Qianlong Emperor presenting the imperial kilns with their greatest ever challenge.

The technique of piercing the walls of a vessel to create an delicate openwork design was known by the Chinese as ling long or 'delicate openwork',  The openwork designs were cut by hand when the clay was 'leather hard'. Both the cutting and subsequent firing would have required great skill. During the Wanli period this technique is  found on fully reticulated bowls, see ones illustrated by M. Medley in Illustrated Catalogue of Underglaze Blue and Copper Red Decorated Porcelains in the Percival David Foundation of Chinese Art, London, 1976, plate XI, nos. B620 and B623, listed p. 57, and Chen Runmin, Selected Chinese Ceramics from the Palace Museum (Volume 1): Blue and White Ceramics in Shunzhi and Kangxi Periods (Qing Shunzhi Kangxi chao qing hua ci), Beijing, 2005, p. 203, no. 124. The workmanship on the present vases is slightly more involved, as they have an inner wall, and the openwork only goes through the outer wall.
