I. Historical Evolution of Yuan Blue-and-White Porcelain and Middle Eastern Art Trade

Although blue-and-white porcelain roots trace back to the Tang and Song Dynasties, its true technical and aesthetic maturity emerged in the mid-to-late 14th century at the Jingdezhen Kilns. This transformation was driven by the Pax Mongolica, which reunited the Eurasian continents and established bustling sea and land Silk Roads.

The signature aesthetic of Yuan blue-and-white relies on Samarra Cobalt (known in Chinese as Sumali Qing), a high-iron, low-manganese cobalt ore imported from Persia (modern-day Kashan, Iran). Islamic potters had utilized this cobalt for low-fired earthenware centuries prior. With the arrival of Persian and Arab merchants and the establishment of the Fuliang Porcelain Bureau by the Yuan court, Middle Eastern tastes—characterized by monumental vessels, dense multi-tiered registers, and geometric medallion layouts—intertwined with native Chinese porcelain technology, literati brushwork, and Yuan drama illustrations. These masterpieces served not only as premium export commodities (as evidenced by the vast collections in the Topkapi Palace and the National Museum of Iran) but also as imperial rewards for noble elites, marking the zenith of cultural synthesis among Han, Mongol, and Islamic artistic traditions.

II. Global Checklist of Recognized Yuan Blue-and-White Vessels with Narrative Scenes

While floral and faunal decorations dominated the era, vessels depicting continuous historical narrative scenes are extremely scarce due to the demanding painterly precision required. The following 12 items denote the globally acknowledged and most representative narrative wares:

III. The Supreme Standing of the “Xiao He Chasing Han Xin” Meiping and its Excavation

1. Why it is Recognized as the “First Porcelain” of Yuan Blue-and-White

The Nanjing Museum Meiping occupies an peerless status in Chinese ceramic history due to three factors:

• Unrivaled Craftsmanship: Standing at an impressive 44.1 cm, it utilizes imported Samarra cobalt to translate traditional ink-wash painting techniques—such as sketching, shading, and washing—directly onto dry porcelain clay, capturing the cool, desolate atmosphere of a moonlit river.
• Impeccable Preserved State: Unlike most excavated narrative shards, this pristine specimen exhibits zero cracks, chips, or restorations; its glaze retains a glowing brilliance.
• Archaeological Context & Exhibition Bans: As a scientifically recovered piece with clear terminal chronology, it has been designated by the State Administration of Cultural Heritage as a Grade-I National Treasure banned from international exhibition.

2. Excavation History and Museum Repository

The Meiping was unearthed in 1950 from the tomb of Mu Ying (the Duke of Qianning and a founding general of the Ming Dynasty) located at Jiangning District, Nanjing. Shortly after the tomb was illicitly opened by a local looter named Kang Yonghai, the vase was offered for sale around the Xinfengkou neighborhood in Nanjing. Chen Newmin, a connoisseur working for the Nanjing Antiquities Company, recognized its unparalleled historical weight and acquired it for the state. It was transferred to the Nanjing Museum, where a dedicated gallery houses it permanently as their crown jewel.

IV. Mineralogical Properties of Ma’an-cang Clay (麻仓土) and its Chronological Diagnostics

Throughout the ceramic history of Jingdezhen from the Yuan to the mid-Ming Dynasty, Ma’an-cang clay (mined from Ma’an-cang Mountain in Dongbu, Jingdezhen) was an imperial monopoly. It acted as the physical linchpin enabling the transition from a unitary formula (porcelain stone alone) to a binary formula (porcelain stone plus kaolin). Its idiosyncratic mineralogical hallmarks provide the most vital geochemical shield separating genuine late Yuan masterpieces from early Ming iterations and contemporary counterfeits.

1. Mineral Composition and High-Temperature Physics

Ma’an-cang clay is a premium hydromica-kaolinite clay characterized by a high aluminum (Al₂O₃) and low iron (Fe₂O₃) matrix.

• Refractory Elevation: The incorporation of Ma’an-cang kaolin boosted the alumina content of the raw clay paste to over 20%. This significantly raised the structural refractory limit, allowing the body to withstand sintering temperatures up to 1300°C without collapsing. It was this property that facilitated the production of unprecedentedly grand, distortion-free late Yuan shapes like massive jars and tall Meiping vases.
• Internal Porosity and Sub-Vitreous Interstices: Because Ma’an-cang was processed using rudimentary ancient levigation methods, minute particles of natural muscovite mica and quartz were preserved. Under high-temperature reduction, these impurities underwent phase transformations, generating sub-microscopic void structures within the fired body. Consequently, genuine Yuan paste achieves a distinct tactile paradox—“coarse but not loose, substantial yet physically lightweight.” It possesses a noticeably lighter handling weight relative to its volume when held side-by-side with denser modern reproductions.

2. Mechanistic Foundations of the “Slick Base” and “Refractory Red”

• The Glissade Base and Glutinous Rice Powder Texture: Due to the crystalline habit of its hydromica base, the unglazed exposed foot rim feels uniquely smooth to the touch, evoking the velvety texture of raw glutinous rice powder (known as Nuomi Tai), rather than the dry, abrasive scratching sensation indicative of modern crushed stone powders.
• Natural Migration of Refractory Red (火石红): Natural iron minerals were unevenly dispersed within the coarsely refined Ma’an-cang paste. During high-temperature reduction firing inside wood-burning (pine) dragon or egg-shaped kilns, internal moisture escaped outward, driving iron ions to migrate toward the unglazed clay surface. During the subsequent cooling cycle, these surface iron clusters re-oxidized into a multi-layered, semi-greasy, naturally haloed refractory red border along the glaze line. By the early Ming Dynasty (Hongwu and Yongle eras), the shallower veins of Ma’an-cang clay were depleted, forcing potters to harvest deeper strata that were chemically cleaner; hence, early Ming refractory reds appear more uniform, less greasy, and skew toward a paler tangerine hue. Contemporary high-fakes utilize modern synthetic chemical kaolin where iron is topically brushed on or mechanically mixed, yielding a static, flat coloration that lacks the organic, depth-outward bleed of authentic Ma’an-cang clay.

V. Macroscopic and Microscopic Examination of the Applicant’s Collection

To establish the authentication parameters of the applicant’s Meiping, a rigorous comparison against the Nanjing baseline specimen was implemented.

Conclusion and Summary

Synthesizing the macroscopic iconographic analysis with microscopic criteria (including decayed bubble formations, natural surface patina, authentic refractory iron-red, and the definitive mineralogical touch of Ma’an-cang clay), the applicant’s “Xiao He Chasing Han Xin” Meiping displays all the chemical, material, and manual markers of a premium late Yuan Dynasty product fired at Jingdezhen. Its extreme stylistic proximity to the national specimen held in the Nanjing Museum marks it as an invaluable artifact for ceramic research and a masterpiece of early blue-and-white art.
