Qingbai Ware from the Song–Yuan Period: Expert Attribution Using the Beynos Method with Museum and Archaeometric Comparisons

The term Qingbai (Chinese 青白, qīngbái) literally translates as “green-white” or “bluish-white” and refers to the distinctive glaze colour — transparent yet tinged with a cool bluish-green tone over a pure white porcelain body. This effect was achieved through wood-fired reduction firing, where the minimal iron content in the glaze produced a “jade-like” cool hue. From the 18th century, the related term Yingqing (影青, yǐngqīng, “shadow-green”) was also used for the same category of wares. Qingbai originated in the Northern Song dynasty (960–1127), flourished in the Southern Song (1127–1279), and continued into the Yuan period (1279–1368). Its principal production centre was Jingdezhen, especially the Hutian kilns, where potters used exceptionally pure white kaolin combined with fine-grained porcelain stone (petuntse) to achieve remarkable whiteness and density. Historic Chinese connoisseurs described the finest Qingbai as 如玉 (“like jade”) or, in more colourful vernacular, as “鼻涕色” (“mucus colour”) — not pejoratively, but as a prized term denoting the soft, slightly misty greenish-blue tone regarded as the hallmark of correct firing and glaze recipe. 📚 Музейные и научные эталоны (Museum & Scientific Benchmarks): Metropolitan Museum of Art — Qingbai ewers with incised floral designs under bluish glaze, Northern–Southern Song transition.

This study presents an in-depth expert attribution of a Qingbai ware ewer from a private collection, employing the Beynos Method, which integrates technological, stylistic, and colorimetric analysis with comparative museum and archaeometric data. Qingbai (qīngbái, “bluish-white”) porcelain, produced primarily at Jingdezhen and Hutian kilns during the Song (960–1279) and Yuan (1279–1368) dynasties, is characterized by its pure white body and transparent glaze with a subtle bluish-green hue achieved in a wood-fired reduction atmosphere. The examined ewer measures 19 cm in height, 13 cm in maximum width, with a 7 cm spout and 6 cm mouth and base diameter. It features a deeply carved floral design (likely peony), smooth jade-like surface, and glaze free of bubbles, iridescence, or restoration.Colorimetric measurements reveal slight tonal variation between flat and relief areas (LCh: flat L = 62.0, C = 10.2, h° = 84.8; relief L = 65.2, C = 3.1, h° = 95.3), consistent with glaze pooling in incised zones. These values correspond to known museum examples (Metropolitan Museum of Art, British Museum, Kimbell Art Museum) and archaeological specimens from Hutian, as documented in Heritage Science. The jade-like “鼻涕色” (“mucus colour”) tone, historically praised in antique literature, aligns with high-quality Southern Song–Yuan Qingbai production.
