Imperial Porcelain Vase with Falangcai Enamels and a Four-Character Yongzheng Mark: Evidence for the First Systematic Use of Falangcai and Relief Grounds in the Late Yongzheng Period

Author: Prof. Nona Dronova, Doctor of Technical SciencesORCID: https://orcid.org/0009-0007-4867-9074 Abstract This study examines an imperial Chinese porcelain vase bearing a four-character underglaze cobalt-blue mark Yongzheng nian zhi (雍正年製, “Made in the Yongzheng reign”). Applying the Beynos Method — developed by Prof. Nona Dronova and published earlier (DOI: 10.5281/zenodo.16786915) — the research evaluates technological, stylistic, and material features to establish attribution. The results confirm that the vase belongs to the late Yongzheng period (1723–1735) and provide evidence that the systematic use of falangcai enamels (珐琅彩) and relief “brocade” grounds (錦地) began under Emperor Yongzheng, rather than later in the Qianlong reign.

D. (2025). Method of Beynos for Porcelain Attribution. Zenodo. DOI: 10.5281/zenodo.16786915. The Beynos Method is based on the Beynos logic (Prof. Nona Dronova) and adapted for porcelain attribution. It enables: comparison of independent features (technological, stylistic, material) with their probabilities of belonging to specific historical periods; updating posterior probabilities as new data are introduced; minimizing subjectivity in expert evaluation; integrating both physico-chemical analyses and art-historical observations into a single model. Introduction The purpose of this study is to demonstrate, through the analysis of an imperial vase with the underglaze cobalt-blue mark 雍正年製 (Yongzheng nian zhi), that the first systematic applications of falangcai (珐琅彩) enamels and relief “brocade” (錦地) grounds belong to the late Yongzheng reign (1723–1735). Key evidence includes: Falancgai as imperial exclusivity: The National Palace Museum (Taipei) identifies falangcai as an imperial exclusive practice institutionalized during Yongzheng’s reign. Dual production system: Jingdezhen provided the porcelain bodies, while enameling and overglaze firing were carried out in Beijing — a process explicitly noted by the British Museum and NPM. Aesthetic refinement: Yongzheng porcelain is described in scholarship as embodying elegance, restraint, and refinement, contrasting with the more opulent style of Qianlong. Relief “brocade” grounds: NPM catalogues confirm falangcai pieces with 錦地 decoration and Yongzheng marks, proving this technique already existed under Yongzheng. Material evidence: Analytical studies (Giannini, Colomban) show eighteenth-century markers such as colloidal gold in pink enamels, Pb-rich glass phases, and cobalt composition, matching the observed features. Thus, the Beynos Method integrates historical sources, museum records, and archaeometric data into a coherent attribution framework. Part I. Attribution Using the Beynos Method Hypotheses H₁ (Late Yongzheng): Jingdezhen body + Beijing enamels; restrained elegance; introduction of falangcai and 錦地 relief. H₂ (Early Qianlong): Technique continued and expanded; decoration became denser, more sumptuous. H₃ (Late Qing / 19th century): Later imitations; different materials and less refined aesthetics. Observations and Evaluation (Beynos Method) Mark 雍正年製: Four-character underglaze cobalt mark in double-square frame — strong support for H₁. Technology: Body from Jingdezhen + enamels from Beijing, confirmed by microstructure. Strong support for H₁. Elegance: Balanced, refined composition with delicate shading — support for H₁. Relief ground 錦地: Documented in NPM examples with Yongzheng mark. Strong support for H₁. Falangcai palette: Colloidal gold in pinks, Pb-rich glass phases — consistent with 18th c. enamels. Support for H₁. Comparative typology: Matches NPM falangcai pieces with Yongzheng marks. Support for H₁. Conclusion of Part I Applying the Beynos Method, the combined evidence strongly supports attribution to the late Yongzheng reign. The vase exemplifies the earliest systematic integration of falangcai enamels and relief “brocade” grounds (錦地), marking a pivotal innovation that shaped Qing imperial porcelain. Conclusion The studied vase, bearing the mark 雍正年製, exemplifies the aesthetic ideal of late Yongzheng porcelain — refined, elegant, and technically sophisticated. Based on the Beynos Method, its attribution to the imperial kilns of the Yongzheng period is confirmed. This demonstrates that the systematic use of falangcai enamels and relief brocade grounds began not in Qianlong’s time, but already during the Yongzheng reign. References Colomban, P., et al. (2022).

EXPERT MUSEUM-STYLE PASSPORT Catalogue No.: FR.YZ.E18.001 Famille-Rose Porcelain Vase “Irises”Height: 40 cmAttributed Period: Early Yongzheng reign (ca. 1723–1730), Qing DynastyPrivate Collection Object Description A rectangular-section porcelain vase with gently waisted sides, flaring shoulder, and short neck. The body is fully decorated in fine famille-rose enamels with a repeating geometric lotus-scroll ground (in pale blue and yellow) and large reserved panels depicting blooming irises and peonies. The upper rim is bordered with intricate floral scrolls on a lemon-yellow ground, and the foot is finished in a turquoise glaze. The base carries a six-character Yongzheng reign mark in underglaze blue, centered within the turquoise-glazed recessed base. Material and Technique Hard-paste porcelain Overglaze famille-rose enamels Hand-applied, multi-stage painting and firing Turquoise enamel base and foot interior Underglaze blue reign mark Heightened relief in floral stamens (notably on the irises), visible under magnification Scientific and Microscopic Observations The enamel ground is evenly applied, with a dense interlocking pattern of blue key-fret motifs and yellow lotus florets. Microphotographs confirm the multi-layered construction of the famille-rose enamels, especially in the petals and yellow scrolls. The violet and pink shades in the flower petals are layered in a highly controlled manner, with visible dotting (pointillism technique) used in the shading. The turquoise glaze at the base shows a consistent microbubble structure and subtle translucency, consistent with early 18th-century enamel recipes. Fine craquelure observed under the yellow enamel, likely due to differential cooling—this is characteristic of Yongzheng imperial famille-rose wares. The footrim is naturally worn and unglazed, with reddish iron staining and kiln grit typical of high-temperature wood- or coal-fired firing environments. Stylistic and Artistic Analysis The composition is extremely refined and shows the restraint associated with early Yongzheng imperial decoration. The design of irises and peonies on a dense patterned ground is unique and exceptionally rare. The geometric pattern of the background and the floral scrolls recall cloisonné enameling and suggest imperial experimentation with optical layering. Slight deformation of the vessel’s panels indicates natural warping during firing due to the rectangular form and large size—this supports the hypothesis of a small-batch imperial experiment. Attribution and Dating The style, enamel technique, palette, and microscopic glaze structure all support an attribution to the early Yongzheng reign (circa 1723–1730). The finely painted six-character reign mark and turquoise base further confirm close relation to imperial ware of this period. The muted palette, restrained symmetry, and complex layering of enamels are entirely consistent with documented porcelain experiments of the early 18th century in the Jingdezhen imperial kilns. Comparative Pieces Compare with a rectangular famille-rose vase with turquoise base in the Palace Museum, Beijing, attributed to early Yongzheng. Similar enamel technique and yellow scroll borders found on Yongzheng falangcai pieces in the National Palace Museum, Taipei. The specific floral rendering technique (multi-layered relief in the stamens) is extremely rare and only found on top-tier palace commissions. Conclusion This vase represents a rare experimental work from the early Yongzheng imperial kilns. Its unusual form, restrained color scheme, multi-layered enamels, and technical sophistication all point to a highly controlled production process under close supervision of the palace. It is a unique and museum-worthy example of high Qing famille-rose porcelain at its most refined stage of evolution.
