  • lack the quaint charm of the coarser Ming and Qing pieces. The Characteristics of Ming and Qing Cloisonne Since no authenticated Yuan dynasty cloisonne is extant, we cannot discuss its appearance. However, numerous Ming and Qing pieces have survived and do allow for technical and stylistic analysis. Unfortunately, since the study of Chinese cloisonne does not have the thorough connois- seurship of the type that allows porcelain to be set into its proper chronological sequence, and since there is a lack of archaeologically exca- vated examples of ancient cloisonne pieces, the dating of many cloisonne pieces is rather diffi- cult. Early Ming cloisonne pieces of the fifteenth century are scarse, much more so than early Ming porcelain. The early pieces are robust in shape, naturalistic in design, sombre in colour, and tend to be rendered in porcelain shapes rather than metal forms. The bodies of these wares are of heavy cast-bronze (or brass) with handwrought bronze cloison wires soldered on. The bronze is an alloy composed of 70-80 per cent copper, 20-30 per cent zinc, and less than 1 per cent lead and tin. The wires, made by hammering from bronze ingots, are often im- perfect and uneven in thickness. Under close examination, one sees that many of the wires show signs of longitudinal splitting because the bronze is very brittle. The wires may have been overworked or there was inadequate annealing (tempering), which causes them to split during the repeated heating process. The force applied during the polishing may also cause splitting. The presence of split wires is often used as a means of identifying a Ming cloisonne piece. The enamel surface on early Ming pieces is far from perfect, and is pitted with holes caused when the zinc in the bronze vaporizes, creating gases that bubble up in the enamel. Discoloura- tion and bubbles also sometimes occurred in the enamel because of the reaction of the melting solder during firing. It seems that some time after polishing, these holes were filled in with coloured wax, which has discoloured over time. The decorations on early pieces are often well spaced and there is little use of background scrolls and spirals to fill vacant spaces like in later pieces. The colours used at this time were turquoise-blue (often used for the background), dark blue (made from cobalt imported from Iran known as Mohammedan blue), red, yellow, dirty white, and, very dark green. By the late fifteenth century mixed colours were developed. Red and white particles were mixed to form a salami-like combination which came to be known as Ming Pink, and later yellow and green were also combined. In addi- tion, the dark blue lost its brilliance due to the lack of Mohammedan blue from Iran, and its replacement by native cobalt caused it to be- come dull and greyish. In the first half of the sixteenth century, several new mixed colours came into use. The designs became more open and varied. The vacant spaces give way to wire outlines in the background, which often form independent decorative patterns of their own and serve to hold the enamel in place. By the late sixteenth and early seventeenth century, large striking temple pieces such as candleprickets, flower vases and incense burn- ers, were made in great numbers. Also at this time finely mixed colours begin to replace the coarser mixtures. By far the most popular motif on Ming cloi- sonne is the lotus, the symbol of the purity of the Buddhist faith. The stem of the lotus is usually formed by a single wire from which buds, spiral tendrils and leaves of various shapes, spring forth. The style of the lotus flower and its leaves, when examined closely, can help to establish a dating sequence for many pieces. Other popular motifs on Ming cloisonne in- clude chrysanthemums, plums, bamboo, cranes, grapevines and squirrels, and ponies galloping over waves. In later Ming designs, the dragon and phoenix, as well as Buddhist and Daoist emblems become popular. In the second half of the sixteenth century elaborate landscape scenes become more numerous, such as scenes with animals and birds as well as human figures in garden settings. This change in decoration on cloisonne follows a similar change which went on in the field of ceramics. Some time in the seventeenth century, which saw the takeover of the Ming dynasty by the Qing dynasty in 1644, major changes take place in the making of cloisonne. The uneven hand- wrought bronze wires of the Ming were replaced by uniform die-drawn copper wires, which have a malleable quality, and eliminated the split wire phenomenon. Also copper began to replace
