1. Core Characteristics
- Body and Glaze & Form
- The body is fine, pure white, and substantial, typical of large Xuande dishes.
- The glaze is lustrous with a bluish tint (commonly called “liangqing” glaze), often showing an “orange-peel” texture.
- The plate is massive (often over 30 cm in diameter), usually with a flared rim, curved sides, and a ring foot, conveying solidity and grandeur.
- Blue-and-White Coloring
- Imported “Sumali” cobalt pigment was used, producing a vivid, deep blue hue with characteristic iron-rust spots and natural diffusion, creating rich tonal layers.
- The lotus motifs are outlined in intense blue, with natural shading that evokes an ink-wash aesthetic.
- Decorative Theme
- Lotus Pattern: Symbolizing purity and integrity, it often appears as scrolling vines, detached branches, or a full “lotus pond” scene, accompanied by leaves, seedpods, and aquatic plants. The composition is dense yet orderly.
- Layout: The center typically features a large lotus bloom, the interior walls are adorned with scrolling lotus, while the exterior may bear scroll grass, wave patterns, etc., creating clear visual layers.
- Technique: The brushwork is free and fluid, with bold, powerful lines reflecting the confident Xuande painting style.
- Marks
- The base often bears the six-character mark in regular script: “Da Ming Xuande Nian Zhi” (Made in the Xuande reign of the Great Ming), enclosed within a double or single circle. The calligraphy is neat and vigorous.
2. Historical and Craftsmanship Value
- Status of Xuande Blue-and-White: The Xuande period is considered the “golden age” of blue-and-white porcelain. The mastery of Sumali blue and painting techniques set a standard emulated by later generations.
- Symbolism of the Lotus: The lotus, representing purity in Buddhist and scholarly traditions, also subtly aligns with the court’s aspiration for “clean governance and virtuous rule.”
- Function of Large Dishes: Such large plates might have been used for court banquets, display, or as diplomatic gifts. Some similar forms were also produced for the Islamic market, reflecting early Ming imperial grandeur and export demand.
3. Authentication and Market Reference
- Caution Regarding Imitations
- Imitations were made in later periods (especially during the Jiajing and Wanli reigns of the Ming, and the Qing Dynasty) and even modern times. Replicas often have a lighter body, overly uniform blue coloring, and stiff marks, lacking the natural iron spots of genuine Sumali blue.
- Collector’s Value
- Genuine pieces are extremely rare, mostly housed in top museums worldwide (e.g., Taipei Palace Museum, British Museum, Beijing Palace Museum).
- They seldom appear on the market. If an authentic piece were auctioned, its estimated value could reach tens of millions of RMB.
