VIETNAMESE UNDERGLAZE BLUE 'CHOCOLATE BOTTOM' DISH, LÊ DYNASTY: ORIGINS & SIGNIFICANCE

A classic Vietnamese (Annamese) blue and white circular dish, likely dating to the 15th or 16th century. The interior basin is decorated in an underglaze cobalt blue with a central archaic seal script motif—most likely a highly stylized 'Shou' (longevity) character or a talismanic seal—surrounded by radiating concentric bands of repetitive, stylized geometric or pseudo-character marks often referred to by collectors as 'magic square' or 'comb' patterns. The exterior wall features two simple concentric blue line borders. The most diagnostically significant feature is the unglazed reverse within the beveled foot rim, which has been applied with a distinctive iron-rich brown wash. This 'chocolate bottom' is the definitive fingerprint of export ceramics produced at the Chu Đậu kilns in the Red River Delta during the Lê dynasty.

EASTERN & WESTERN ECHOES

Where This Object Echoes

Ming Dynasty China15th-16th Century

Provincial kilns (like Swatow/Zhangzhou) also produced heavily potted, slightly gritty export wares for the same Southeast Asian markets, though utilizing different base treatments.

Ritual & Ceremonial Use

  • •These dishes were extensively exported to the Indonesian archipelago, where they were often kept as sacred heirloom possessions (pusaka) by indigenous communities rather than used for daily dining.

Meaning Through Time

Ming/Lê Transition

From a utilitarian, mass-produced export substitute filling a trade gap to a treasured tribal heirloom in destination cultures.

EASTERN PROVENANCE

During the 15th and 16th centuries, the Ming Dynasty in China periodically enacted the 'Haijin' (sea ban), strictly limiting private maritime trade and creating a massive supply vacuum in the Southeast Asian ceramics market. Vietnamese kilns, particularly those at Chu Đậu, seized this opportunity, enjoying a 'Golden Age' of ceramic production. They exported millions of underglaze blue vessels to markets in modern-day Indonesia, the Philippines, and Malaysia. The characteristic 'chocolate base' was a unique regional innovation. Scholars debate its exact purpose; it may have been applied to seal the somewhat porous local clay, to emulate the dark bases of favored Chinese Longquan celadons, or simply to serve as a recognizable trademark for merchants identifying the ware in stacked cargo holds.

EASTERN FOOTNOTES

1

The 'chocolate bottom' on Vietnamese export wares is solely an iron-oxide wash, not a true glaze, and was usually applied with a broad brush or poured directly onto the unfired clay.

2

Many similar pieces were recovered from the famous 'Hội An Hoard' shipwreck, discovered by fishermen in the 1990s, which yielded over 250,000 intact Vietnamese ceramics.

HOW SCARCE IS IT?

Uncommon70-80%
CommonLegendary

Genuine antiques with fewer examples on the market. Named makers, documented provenance, or early production examples.

Typical Characteristics

  • Limited production
  • Named makers
  • Growing collector demand

Confidence Factors

  • Modern reproductions of Chu Đậu wares have increased since the Hội An Hoard discovery.
  • However, the matte texture of the brown slip and the specific inky bleed of the cobalt in these images strongly align with period-correct firing characteristics, mitigating the risk.
How does authenticity detection work?

ASIAN ART SCHOLAR'S TAKE

Asian Art Specialist

East Asian Art Expert

The 'chocolate base' is arguably the most recognizable fingerprint in Southeast Asian ceramics. The visual execution of both the base wash and the specific underglaze blue motif strongly matches documented 15th-16th century Vietnamese examples.

KEY EVIDENCE

  • 1Presence of the 'chocolate base'—an iron-oxide wash applied to the unglazed foot, diagnostic of Vietnamese ceramics.
  • 2Slightly grayish-blue inky underglaze cobalt, typical of local Vietnamese ore and firing conditions.
  • 3Archaic/talismanic central seal and radiating repetitive borders, classic motifs of the Chu Đậu kilns.
  • 4Beveled foot rim cut, customary for Annamese potting techniques of the era.

UNCERTAINTIES

  • •Lack of tactile access prevents assessing the exact density of the paste, but visually there are no major red flags for authenticity.

WHAT WOULD IMPROVE CERTAINTY

  • →Examine the rim under UV light to ensure there are no disguised restorations or filled rim frits.
  • →A close-up macro examination of the glaze surface to look for age-appropriate micro-scratching and authentic glaze degradation.

CONDITION & GRADE

Condition

Displays minor wear consistent with significant age, as noted by the user. No major chips or structural cracks are immediately visible in the provided angles. The chocolate wash on the base is nicely intact, and the glaze appears free of the heavy saltwater degradation often seen on shipwreck-salvaged examples.

Surface

The underglaze cobalt exhibits the slightly grayish, inky pooling characteristic of Vietnamese kilns, sitting beneath a faintly greenish-tinted, somewhat soft glaze. The unglazed base bears a matte, earthy, iron-rich brown slip with a few minor firing anomalies and kiln dust inclusions.

Weight & feel

Robust and likely slightly heavier in the hand than an equivalent Jingdezhen Chinese porcelain dish, indicative of the denser, less refined stoneware-like paste of provincial Annamese kilns.

ASIAN ART VALUATION

$200 - $450

Updated: Apr 19, 2026

Who buys this

Collectors of Southeast Asian ceramics, shipwreck artifact enthusiasts, and scholars of the Ming-era maritime silk road trade disruptions.

What increases value

  • •Absence of sea-water degradation (coral marine growth or glaze dulling common to Hội An Hoard pieces)
  • •Crispness and uniqueness of the central talismanic character
  • •An even, well-applied chocolate base with strong coloring

What lowers value

  • •Hairline cracks or repaired rim frits (very common in these wares)
  • •Blurring of the cobalt blue caused by firing temperature issues

What makes top-tier examples

  • •Clear, dark, inky blue cobalt contrasting sharply against a bright, un-degraded white glaze
  • •Perfectly intact rim with no 'flea bite' chips

Grade & condition

Condition of the rim (fritting), clarity of the underglaze blue design, and integrity of the glaze surface (lack of shipwreck degradation).
