Ming Xuande ‘blue-ground with white fish and lotus’ dish

• Period: Ming Dynasty
• Reign Mark: Xuande (1426-1435 AD)
• Technique: Blue-ground with white decoration (“reverse blue-and-white”)
• Pattern: Lotus pond with two fish and aquatic plants
• Form: Dish

Detailed Feature Analysis:

1. Form:
   • Flared rim: The mouth rim spreads outwards.
   • Shallow, rounded sides: The walls are curved and not deep.
   • Flat base, ring foot: The bottom is flat, standing on a circular foot.
2. Decoration and Technique:
   • Blue-ground with white design: This is a prized technique from the Xuande period. Instead of painting blue designs on a white ground, the cobalt blue was applied to the background, leaving the reserved motifs in white. These white designs were then outlined.
   • Lotus pond with two fish in reserved white with trailed slip lines: A precise description of the technique and theme.
     • Reserved white: Refers to the motifs created by the “blue-ground” technique.
     • Trailed slip lines: Indicates that the white designs stand slightly proud of the blue background, creating a subtle raised effect and a sense of depth.
     • Lotus pond with two fish: The primary decoration depicts a pond scene with lotus blooms, leaves, and water weeds, through which two fish swim. This motif was a classic Xuande theme, symbolizing abundance and wealth.
   • Fish eyes dotted in underglaze blue: A vivid detail. The eyes of the white fish are dotted with cobalt blue, making them strikingly lifelike.
   • A single white line encircles the center and the foot: Adds a framing element to the central motif and the foot.
   • The rim and foot rim are left as a white border, glazed a faint bluish-green: The edges of the rim and foot are unglazed, revealing the white body, and have a faint bluish-green tint. This is a characteristic feature of Xuande porcelain at the juncture where the glaze thins.
3. Glaze and Body:
   • Rich blue with a purplish tint: Describes the color of the blue ground. Achieved using imported Sumali blue cobalt, which produced a deep, vibrant blue, often with a purplish hue or silvery “heaped and piled” spots.
   • The body is evenly potted. The unglazed foot rim reveals a fine-grained body with occasional iron spots:
     • Evenly potted: The clay body is uniformly thick and well-formed.
     • Fine-grained body: The clay used for Xuande imperial wares was meticulously refined.
     • Iron spots: The unglazed foot often shows reddish-brown spots caused by iron impurities in the clay oxidizing during firing, known as “fire-red” or “iron rust.”
   • The junction of body and glaze shows a light orange line: The line where the glaze meets the bare body (typically on the foot rim) exhibits a light orange-red tone, a key authentication feature for Xuande wares.
4. Mark:
   • The base bears a six-character reign mark in underglaze blue, Da Ming Xuande Nian Zhi (“Made in the Great Ming Xuande period”), in two lines of standard script (Kaishu): The base is inscribed with the six-character mark in two vertical lines. Xuande marks are known for their variety and can appear almost anywhere on a vessel, but are most common on the base of dishes and bowls. The calligraphy is powerful and vigorous.

Summary

The object you described, this Ming Xuande ‘blue-ground with white fish and lotus’ dish, is a quintessential masterpiece embodying the peak of Xuande imperial porcelain production:

• Technical Mastery: The “blue-ground with white” technique was more challenging than standard underglaze blue and had a lower success rate, making it rarer and more valuable.
• Characteristic Cobalt Blue: The use of Sumali blue resulted in the rich, purplish-blue tone typical of the period.
• Vivid Decoration: The lotus and fish motif is compositionally balanced and lively, with masterful details like the blue-dotted fish eyes.
• Diagnostic Body and Glaze: The fine body, iron spots, fire-red, and light orange body-glaze junction are all key authenticating features.
• Standard Mark: The underglaze blue Kaishu mark confirms its imperial Xuande origin.

This piece is not merely a utilitarian object but an artifact of immense artistic and historical value, representing the zenith of early Ming imperial kiln production. Such pieces are typically found in major museums (like the National Palace Museum in Taipei or the Palace Museum in Beijing) or appear in prestigious auctions.
