Blue-and-White Moon Flask with Intertwining Floral Scrolls

Face on, it's a full moon. Turn it, and the body flattens into a slim crescent. That's why the Chinese call this shape baoyueping, "the vase that embraces the moon."

Every inch of the surface is covered in cobalt blue: peonies, chrysanthemums and composite baoxiang blossoms joined by one continuous scrolling vine, so the pattern never really begins or ends. The painter worked in several shades of blue (fen shui), letting some petals sit darker and others fade almost to white.

Two curling chilong dragons form the handles at the shoulders, and a six-character Qianlong reign mark in seal script is painted on the base.

The defining feature of blue-and-white porcelain lies in its underglaze-blue technique, in which cobalt-based pigment is painted directly onto the porcelain body before being coated with a transparent glaze and fired at high temperature in a single firing. This process produces the striking contrast between brilliant cobalt blue decoration and a luminous white porcelain ground that has become the hallmark of Chinese blue-and-white ware.

The form of this twin-handled flattened flask, commonly known as a Moon Flask (baoyueping), originated during the Ming Dynasty and achieved particular popularity during the Kangxi, Yongzheng, and Qianlong reigns of the Qing Dynasty. Its flattened circular profile reflects artistic influences from West and Central Asia, where such vessels were valued for their portability during travel, while its decoration incorporates traditional Chinese motifs, most notably intertwining floral scrolls, which symbolize continuity, prosperity, and the unending cycle of life.

The present vessel displays a rich, vibrant underglaze-blue palette and a meticulously balanced decorative scheme of remarkable complexity and refinement. If an original work, it would likely represent a fine example of Qing imperial kiln production. If produced in the modern era, it stands as a faithful revival of a classical design tradition, combining ornamental elegance with enduring cultural significance.

The mouth rim and neck are decorated in carefully defined horizontal registers featuring intertwining lotus scrolls and ruyi cloud-head motifs. The underglaze-blue decoration exhibits expertly controlled tonal gradation (fen shui), producing a refined interplay of deep and pale cobalt hues, while the ornamental borders are executed with exceptional precision and symmetry.

The pair of chilong (hornless dragon) handles are crisply modeled with sharply defined contours. Their dragon heads display finely rendered facial features, and the seamless transition between the handles and the body demonstrates a highly accomplished manufacturing process, indicating that the vessel was successfully fired as a unified whole.

The flattened body is richly decorated with an all-over composition of intertwining peonies, chrysanthemums, and baoxiang (composite floral) blossoms linked by gracefully scrolling vines. The continuous floral scrolls symbolize enduring prosperity, abundance, and peace throughout the four seasons, making them among the most auspicious decorative motifs in Qing imperial porcelain.

On certain imperial kiln examples, a stylized longevity peach is subtly incorporated into the central field of the body. This discreet motif conveys the traditional blessing of fu and shou—happiness, good fortune, and long life—adding an additional layer of symbolic meaning to the vessel's decorative program.

The base bears the standard six-character reign mark of the Qianlong period, arranged in three vertical columns and executed in meticulously composed seal script. The calligraphy is distinguished by its disciplined structure and vigorous brushwork, with the turning strokes preserving the expressive rhythm and modulation characteristic of brush-written script. Rendered in the same underglaze-blue pigment as the vessel's painted decoration, the mark displays a consistent cobalt tone and quality, reflecting the unified execution of the entire piece. The style, calligraphy, and cobalt characteristics of the reign mark constitute one of the principal criteria for identifying porcelain produced by the Qianlong imperial kilns during the reign itself.
