Bianhu Moon Shaped Flask
China, Qing Dynasty, 1644–1911, reign of the Emperor Qianlong (1736–1795)
Porcelain with “clair de lune” glaze
DBC 10761.1
Originally made as a wine container in bronze, the bianhu or flattened hu shape was used for centuries. Qing potters were renowned for their monochrome glazes of which clair de lune or sky blue (tian qing) is one of the most treasured. The blue tint comes from cobalt oxide. There is a Qianlong reign mark in underglaze blue on the base.
The marble technique was developed in the Tang dynasty when extraordinarily proficient potters twisted and kneaded together two different color clays to achieve a pattern reminiscent of wood grain. It was then covered with a clear glaze. Vessels made with this technique are rare, especially in this full, round form.
The most important innovation in ceramics during the Yuan dynasty was painting designs in cobalt blue on porcelain then coating the piece with a clear glaze, which at that time had a slight bluish cast. These two thickly potted globular jars are decorated with sketchily painted flowers.
Iron began to be applied in spots on Qingbai ware during the Yuan dynasty. This would have been considered outrageous during the preceding Song dynasty when the rulers prized purity and restraint. The double gourd-shaped ewer sports a dragon handle. The vase is an unusual form with double handles and is raised on a pierced lozenge-shaped openwork base. Both were made for export throughout Southeast Asia, especially the Philippines.
This wine ewer has six lobes, a curved slender spout, and a lion-topped lid. The bowl, which would have held warm water, is in the shape of a lotus flower. Both are delicately incised and coated with a pale blue glaze. It is remarkable that the ewer and bowl have remained together.

Ewer or Kendi
China, Qing Dynasty, 1644–1911, reign of Emperor Kangxi (1662–1722)
Porcelain with underglaze blue and overglaze enamels and gold
DBC 11001.1/2
The palette and style of the decoration on this ewer was inspired by Japanese Arita-ware Imari porcelains. It combines blue and iron red to depict a flowering prunus tree and was made specifically for export.

Kendi
China, Ming Dynasty, 1368–1644, Xuande Period, 1426–1435
Porcelain with underglaze copper red
DBC 10666.1
The crescent-moon shape of this kendi suggests it was made for export to Islamic countries in Southeast Asia, possibly Indonesia. It is decorated with a five-claw dragon in reverse on the white ground and bears a six-charter Xuande reign mark. The copper-red underglaze was very difficult to control in the kiln.

Jar
China, Neolithic Period, Majiayao Culture, 3300–2000 BCE, Machang phase
Painted earthenware
DBC 10297.1
Large jars like this were used to store water or grain. They were coil built and kiln-fired at about 900 to 1000 degrees centigrade. The exuberant painted geometric decoration indicates the earliest use of a bruch in China. Surviving examples have usually been found in tombs.

Gu-form Vase
China, Ming Dynasty, 1368–1644, 17th century
Dehua porcelain
DBC 10514.1
Kilns in the vicinity of the town of Dehua in Fujian created fine-grained, vitreous white porcelains coated with a thick, smooth white glaze. They came to be known as blanc de Chine or China white. The shape of this vessel is based on the classic bronze wine goblet form, gu.
This rare, fine libation cup was used in ritual ceremonies. It has a clay pellet inside to produce a musical sound. The perforations permit air to circulate during firing as well as to decorate the vessel. It is thinly potted and has a natural ash glaze.

Stem Cup
China, Neolithic Period, Longshan Culture, 3000–1900 BCE
Black earthenware
DBC 11077.1
Fashioned from fine-grained clay, trimmed on a wheel to eggshell thinness and burnished, wares like this cup were fired to about 1000 degrees centigrade in a reduction kiln atmosphere. Reducing the oxygen in the kiln resulted in the iron-rich clay turning black. They were used in rituals and have been largely found in burials.
Kimhae ware is named for the southern coastal region where it was made from about the 1st to 4th centuries CE. It was wheel thrown and fired in a climbing or tunnel kiln. It is decorated with an incised comb pattern.
