Blanc de Chine
Enriched by geology and mysterious fortune, ancient masters perfected a rare, beguiling family of ceramics
Examine a piece of blanc de chine, and fantastic notions seem suddenly yet undeniably real. Spindly dragons wriggle and cavort across delicate pitchers and vases. Blossoming flowers unfold their veined petals upon intricate teacups. Smiling Buddha figures pose and pause in midgesture. The rich white surface, lustrous as an oyster's pearl, appears to be alive.

When it debuted on the world market more than 400 years ago, this remarkable porcelain found an eager audience. The organic shapes and creamy, vitreous textures inspired a lasting demand, first with Chinese scholars, monks, and rich merchants, then with European aristocrats, and eventually among well-heeled Westerners. Familiar to the English as "white wares" and to the French as blanc de chine (literally, "white of China"), these singular fired crafts were recognized as bai ci ("white porcelain") or "Dehua ware" in their country of origin.

Dehua, a county of rolling hills and rivers in southeast China's Fujian Province, emerged as a regional ceramics hub long before its global legacy took root. "The Dehua kilns date to the Song dynasty (960-1279). But production of the porcelain now known as blanc de chine began in the 16th century and peaked in the 17th and 18th centuries," says Donald Wood, chief curator and curator of Asian art for the Birmingham Museum of Art.

At that time, making porcelain was an intensive endeavor of manual collaboration and specialization. A great number of kilns were established in provincial villages, where natural resources and skilled hands proved plentiful. "It became a big industry and required a definite division of labor. Artists were paid by the piece, and each kiln could hold thousands of pieces. There were sculptors, experts in glazing, firing masters, overseers, and so on," says Wood. "They were making things that they found marketable. Porcelain was a luxury item."

Thus, the muses of art and commerce struck an alliance at Dehua -- with ample assistance from the fortunes of geology and geography. In Blanc de Chine: The Great Porcelain of Dehua, author Robert H. Blumenfield observes, "the whiteness of blanc de chine is due to the relative absence of iron in the local clay." Known as pai tz'u ("white clay") or kaolin ("high ridge" clay), deposits of this substance appeared chockablock in Dehua's landscape. The mineral feldspar, the porcelain's second key ingredient, is also present in the area in prodigious quantities.

The clay, once harvested and painstakingly washed, was combined with powdered feldspar and pressed, wheel-turned, or molded. Kiln-ready pieces were fired at extreme temperatures (at least 1,450 degrees Celsius), bonding and transforming the clay and feldspar into a substance reminiscent of ivory. Distinctive glazes made of feldspar, lime, and potash enhanced the porcelain's natural white hue. The finished stock was exceptional -- dense and strong with a translucent shimmer.

Incidental or intentional variations in clay, glazes, and methods yielded a surprisingly broad palette. "We see a range of colors in blanc de chine, from a brilliant snow white to yellow and pink tints to an almost gray tone," says Wood. Different-colored glazes were occasionally used, and legitimate specimens exist in hues of purple, blue, brown, or green.

As enthusiasm progressed from grassroots interest to an international scale, the kilns followed suit. Offerings ran the gamut, from kitchenware to made-to-order exports. Buddhist or Taoist statues and assorted everyday items, such as bowls, cups, jars, and pitchers, were traded domestically and in surrounding Asian nations.

Although not impossibly rare, high-quality pieces remain something of an enigma. Wood encourages collectors to work with a ceramics expert or reputable dealer to investigate authenticity. "Verifiable age, good condition, and distinguishing seals or marks are always preferred," he says.


COLLECTOR'S CHECKLIST
Finding and acquiring blanc de chine is rarely a matter of estate sale bargain-hunting. "The market is filled with fakes, and many are remarkably close to the real thing," says Salvador Trabanino, collector of Chinese antiquities and "unofficial conservator" and researcher for Asiantiques in New Orleans. To weed out duplicates and knock-offs, remember these suggestions and field tests.
Examine the details: Clues abound in corners, creases, junctions, and the folds of figures' clothing. Inspect these nooks and crannies carefully. "Where the glaze collected in recesses, it should have the look of old Scotch tape," Trabanino says.
Bring a flashlight: Literally. Quality blanc de chine exhibits a shrimplike translucence when exposed to direct light. And, the reflected tint can approximate the porcelain's age. "With early 17th-century pieces, the light appears orange. The light is yellowish on 18th-century examples, and later 19th-century pieces give off white light," says Trabanino.
Tickle the ivories: The sumptuous, ivory patina so often associated with blanc de chine is no guarantee of great age. "The tone can be easily copied or imitated," Trabanino says. Thermoluminescent testing, though expensive and somewhat invasive, is a much more accurate dating method for ceramics.
Never forget a face: "Watch for small mistakes in iconography or facial expressions," Trabanino says. For example, true Guanyin figures, which depict the Buddhist goddess of mercy and were produced in great volume, should have lowered or half-closed eyes and a peaceful forbearance.
Take a peek inside: Initially, technology did not afford finite control of the kilning process. "In the 17th and early 18th centuries, the walls of the porcelain were very thick, with cracks on the inside, due to firing difficulties. The problem was eventually corrected, and later pieces are hollow with thinner walls," says Trabanino.
Make it personal: Beware of any instance where offerings cannot be inspected. Private collectors and trade shows are among the more reliable sources of blanc de chine. "With online auctions, you cannot be sure what you're getting," Trabanino says. "It is best to work with a reputable gallery."

EVOLUTION OF THE KILNS AT DEHUA
A thousand-year history of ceramics production distinguishes the Dehua region of Fujian Province in southeast China. Through decades and centuries, kiln design and technology improved, affording artists more control of firing temperatures and methods. The result? Porcelain of great distinction -- including the area's hallmark, blanc de chine. Here are notes on the types of kilns used at Dehua.
Beehive kilns: An older form, named for its resemblance to a brick beehive. A ceiling flue and ventilation damper allowed some temperature control. Pieces were stacked within, above a coal-fueled fire. A comparatively small apparatus at 10 feet high, the beehive could not hold as much stock for firing as later designs.
Long kilns: An especially ancient form, consisting of single or multiple firing chambers. Heat was channeled among the sections, circulating more efficiently than in beehives. Thick-walled and wood-fired, long kilns also reached higher temperatures (yielding better porcelain) and held more pieces than beehive kilns.
Step kilns: Also known as dragon or snake kilns, this form appeared during the Song dynasty. Long and chambered, they were built into hillsides to make the most of rising heat. Easy to regulate, these kilns offered fast heating and great firing capacity (up to 25,000 pieces). The zenith of timber-fired designs, step kilns remained in use through the 1960s, when electric models replaced them.
