Ru-type Bowl with Dragon Motif

1. Physical Description

This finely potted bowl is of shallow rounded form, with a gently everted rim resting on a short ring foot. The interior is delicately incised with a coiled dragon amid wisps of cloud, its body rendered with rhythmic scales and flame details. The exterior is decorated with molded petal panels rising from the foot toward the rim, enhancing the vessel’s sculptural quality.

The surface is covered in a thick, translucent bluish-green glaze, historically described as “the color of the sky after rain.” The glaze is suffused with a soft, almost oily lustre and a fine, evenly distributed crackle, pooling naturally in the recesses of the carved and molded designs. Three small “sesame-seed” spur marks remain visible on the base from firing supports, a diagnostic feature of Ru ware. The unglazed footrim reveals a dense, fine-grained grey stoneware body. Subtle blushes at the rim and surface variations attest to the alchemy of kiln firing.

2. Formal & Technical Features

• Form: Shallow bowl with thin but not eggshell-thin walls, flaring gently to a slightly everted rim. The profile is simple and restrained, in keeping with Northern Song ideals of understated elegance. While many Ru bowls are undecorated, incised motifs such as dragons, combined with molded petal panels on the exterior, are attested among Song examples.
• Lotus Motif : The overlapping lotus-petal patterns on this vessel reflect a symbol of purity and moral integrity in the Song dynasty. By shaping ceramics in the form of lotus blossoms, artisans expressed the refined and restrained aesthetic ideals of the period.
• Glaze: Thick bluish-green glaze with soft, oily lustre, characteristic of Ru ware. The glaze extends nearly over the entire vessel, pooling slightly at the rim and within carved recesses. Fine crackle is evenly distributed across both interior and exterior surfaces.
• Base: Fully glazed except for three minute unglazed spur marks from kiln supports, arranged in a triangular pattern. This firing evidence is diagnostic of Ru kiln practice, where 3–5 marks are typically observed.
• Body: Dense, fine-grained grey stoneware body. Thinly constructed, though here slightly heavier than the most delicate imperial Ru wares.

3. Comparative Notes

• Ru Characteristics: The combination of bluish glaze of “sky after rain” tone, oily lustre, and sesame-seed spur marks situates the piece securely within the Ru kiln tradition at Qingliangsi.
• Body Thickness: Imperial Ru wares are often exceptionally thin-walled; this example is slightly thicker, consistent with works attributed to subsidiary kiln production, likely intended for use beyond the highest court commissions.
• Distinction from Other Kilns: The cool, translucent glaze tone contrasts with the greener, denser surface of Guan ware, the opalescent lavender splashes of Jun ware, and the ivory-white Ding body without spur marks. Unlike Ge ware, the crackle here is fine and subtle, not bold “iron-wire and golden-thread” lines. Positive and negative features together support a Ru attribution.

4. Attribution Notes

On the basis of form, glaze, and firing traces, the bowl may be attributed to the Ru kilns of Qingliangsi, Baofeng, Henan, and dated to the late Northern Song dynasty (c. 1086–1125), under the reign of Emperor Huizong. The carved dragon within, together with the molded petal-form exterior, suggests an association with courtly taste and symbolism, even if the slightly thicker body indicates production outside the most refined imperial group.

5. Proposed Attribution

Stoneware with thick bluish-green glaze (“sky after rain”), incised dragon and molded petal design. Diameter 18 cm; height 6 cm. Fully glazed, with three sesame-seed spur marks on the base. The body is slightly thicker than the finest imperial examples, suggesting a piece produced within the Ru tradition for high-ranking, though not exclusively courtly, use.
