BLUE AND WHITE PORCELAIN BIANHU MOON FLASK: IDENTIFICATION
A blue and white porcelain bianhu or moon flask featuring a flattened globular body and a slender neck with a flared rim. The exterior is decorated with an underglaze cobalt scrolling floral vine motif. A six-character horizontal mark reading 'Da Ming Xuande Nian Zhi' is situated on the shoulder. The base illustrates an unglazed, recessed oval footrim with visible iron-spotting and apparent artificial distressing.
Compare with other Asian art pieces in the archive: Japanese Lacquer Inrō with Dragonfly and Insect Motif, Chinese Sancai-Glazed Pottery 'Horse-Headed' Zodiac Figure, Tang Dynasty Style, Fencai Enameled Porcelain 'Prunus and Lingzhi' Bowl.
DYNASTY & PROVENANCE
The bianhu form originated from Middle Eastern metalwork and was adopted into the Chinese ceramic repertoire during the Yongle and Xuande periods (1403–1435) of the Ming Dynasty. While this vessel bears the apocryphal mark of the Xuande Emperor, the mechanical application of the cobalt 'heaping and

piling' effect suggests a 20th-century production intended to emulate the 15th-century 'Su-ni-po' imported cobalt aesthetics. Numerous examples of this specific reproduction style appeared in the international trade markets between 1980 and 2010.
SCARCITY
Typical antique shop fare. Requires some searching but regularly available. This is where most genuine antiques fall.
Typical Characteristics
- Standard antique shop items
- Regularly available
- Moderate collector interest
Observed factors
- Uniform mechanical appearance of the cobalt 'heaping and piling' spots
- Artificial distressing and topical staining on the unglazed footrim
- Calligraphy style of the Xuande mark lacks the period-correct fluid brushwork documented by the National Palace Museum
Expert review recommended. Consider consulting a specialist before making purchasing decisions.
ASIAN ART SCHOLAR'S TAKE
Ceramics Historian & Kiln Specialist
Clear images of the mark and base provide sufficient evidence to identify this as a high-quality modern reproduction despite the authentic vessel shape.
KEY EVIDENCE
- 1The 6-character mark 'Da Ming Xuande Nian Zhi' is applied in a static, non-authentic hand.
- 2The 'orange peel' texture on the glaze is indicative of modern high-fire gas kilns rather than traditional wood-fired kilns.
- 3The base staining is uneven and topical, failing to show the characteristic 'orange-skin' oxidation where the body meets the glaze edge.
- 4Scrolling vines exhibit a lack of spontaneous brush movement characteristic of early 15th-century imperial porcelain.
UNCERTAINTIES
- •Cobalt dots are too regular and lack the 'metallic luster' found in genuine 15th-century manganese/iron blooms.
- •The base appears deliberately rubbed with dirt or grease to simulate age.
WHAT WOULD IMPROVE CERTAINTY
- →Direct sunlight photography to inspect for subsurface bubbles (modern vs. ancient).
- →Examine the interior of the neck for evidence of slip-casting mold lines.
- →Weight check against known 15th-century dimensions for body density analysis.
COLLECTOR GLOSSARY (3 terms)
- Heaping and Piling
- The concentration of cobalt blue in certain areas, creating dark, textured spots due to iron impurities in the ore.
- Bianhu
- A flattened peregrine-style bottle or moon flask shape.
- Footrim
- The unglazed ring at the bottom of a vessel where it rested in the kiln.
CONDITION & GRADE
Condition
The unglazed base shows heavy brownish staining that appears to be applied soot or pigment rather than century-deep oxidation or kiln-grit adhesion. No visible cracks or chips on the body surface.
Weight & feel
Likely substantial and bottom-heavy, weighing approximately 2.5 to 3.5 kg based on standard modern slip-casting wall thicknesses.
ASIAN ART VALUATION
Updated: May 10, 2026
Similar 20th-century 'Study of Xuande' flasks typically achieve between $300 and $800 at regional auction houses such as Eldred's or Leslie Hindman.
Who buys this
Primarily sought by interior decorators and entry-level collectors look for the Ming aesthetic without the multi-million dollar price tag of originals.
What increases value
- •Large size and decorative symmetry
- •Popularity of the moon flask form in Asian art displays
- •Clarity of the blue and white contrast
What lowers value
- •Confirmation of modern origin significantly caps the value compared to period pieces
- •Excessive artificial staining on the base can deter buyers wanting a cleaner aesthetic
What makes top-tier examples
- •Hand-thrown body rather than mold-cast
- •Use of high-quality cobalt that mimics the depth of Su-ni-po ore
- •Expertly rendered imperial marks
Grade & condition
Glaze integrity, clarity of cobalt painting, and absence of modern kiln chips define the value of reproductions.
