DO NOT Remove Verdigris From Chinese Antique Bronzes

Verdigris, what some people refer to as green “gunk” on Chinese antique bronze, is a natural form of patina that accumulates over time on copper, bronze and brass as it is exposed to air. In addition to varying shades of green, it may also be bluish green in color. It can also be induced using acids, and sometimes is artificially applied to new items made of these metals, especially copper.

The history of Chinese cloisonne and the production of it’s ‘free standing’ objects is a surprising one. The art of cloisonne was commonly used during medieval times in most of Europe, England, the Middle-East, and the near East, on small accessories and jewelry. In fact this era coincided with the use of stained glass windows in Christian churches, and the understanding of how glass could be transformed, colored and shaped for many uses.

For cloisonne, glass flux was fired in metal cloisons, meant to reproduce the jewelled effect of precious stones in their primitive straight settings. Many cloisonne body ornaments have been found in tombs dating B.C. Today, international museums are displaying examples of Byzantine, Celtic, Persian, Egyptian, Slav, Greek, Islamic and Russian cloisonne pieces, from the B.C. and A.D. periods.

By the early 15th century, with the strong trade going to the Far East from the Near-East along the silk-route from Europe, Persia and India, cloisonne objects and other artistic crafts found their way to China and Japan. Cloisonne was adopted and became a refined and appreciated decorative medium, by the MING Dynasty emperors (1368-1644), and continued to be promoted and selectively produced from then on.

Tianbai Glaze (Sweet White)


White porcelain was of special significance for the court during the Yongle reign (1403-24). The sophistication of the production of white-glazed porcelain during the Yongle period of the Ming dynasty may be attributed to the Emperor’s personal fondness for white vessels.

The production of white-glazed porcelain during the Yongle period achieved technical virtuosity, distinguished by the very fine white body clay and luminous white glaze, which earned the name tianbai or ‘sweet white’ glaze. Tests, conducted on excavated pieces of Tianbai wares from the Site of the Ming Imperial Factory at Jingdezhen, discovered that the pure white porcelain resulted from the combination of a kaolin-rich paste with very low iron and titanium content and a glaze containing mainly glaze stone and no glaze ash.

Chinese Tang Sancai Tri Colour Glaze

Tang sancai refers to the tri-coloured glazed pottery of the Tang Dynasty (618-907 A. D.), a painted earthenware which appeared in the wake of celadon. It is called “tri-coloured ” because yellow, green and white were normally used, although some pieces are also in two or four colours. Developed on the basis of the green and brown glazed- pottery of the Han Dynasty, it represented a peak in the development of Chinese ceramics and was already well-known in the world in its time.

Unearthed tri-coloured Tangs are usually horses, camels, female figurines, dragon-head mugs, figurines of musicians and acrobats, and pillows. Of these, the three-coloured camels have won the greatest admiration. They are presented as bearing loads of silk or carrying musicians on their backs, their heads raised as if neighing; the red-bearded, blue-eyed drivers, clad in tunics of tight sleeves and hats with upturned brims, reproduce true-to-life images of men from Central Asia of that time as they trudged along the Silk Road to the tinkle of camel bells.

The colour blue gained recognition during the Tang dynasty (618 – 907). The colour comes from cobalt ores.

The cobalt pigment is one of the few that can stand the highest firing temperatures that are needed for porcelain.

Mother of Pearl

What is mother of pearl (nacre) ? It is a smooth shining iridescent substance formed on the inner layer of some molluscs, like the oyster and abalone.

Mother of pearl has been used for centuries as a decorative inlay on lacquer ware. It was first thought that mother of pearl oyster beds existed in three regions, the Persian gulf, the red sea and the Sri Lanka coast, but explorers soon found pearl oysters throughout tropical waters. The shells were harvested and exported around the world as people became enamored by this lustrous marvel from the sea.
