White tire thick glazed celadon is also affected by the Southern Song Dynasty official kiln, the tire is slightly thick, white with gray, circle foot, the bottom of the tire is red or light purple, most of the green glaze glaze is not clean, glaze has powder blue, Mei Ziqing and so on nail central. The Southern Song Dynasty Longquan Day Kiln Meizi Qing Bafang Guanxun Southern Song Longquan Kiln creatively invented the lime-alkali glaze instead of the lime glaze used in the past, so that a thicker glaze layer can be obtained with less glazing times nail central. This simplifies the multiple glazing invented by the Southern Song Dynasty kiln, and the method of multiple firings not only makes the celadon more green, but also makes the glaze sleek as a pile of fat nail central. Therefore, the burnt color of the plum glaze of the emerald color is burned, which makes the Longquan celadon process reach a historical peak nail central. The best glaze color of Longquan Kiln is generally pinkish blue nail central. Because the firing temperature is close to 1300 degrees, it is higher than the 1230 degree of pink glaze, so the glazed surface is more vitrified, and the glaze is green and green, like green mountains and rivers nail central. Although the value of ancient green glaze is higher than that of Meiziqing, today people’s aesthetics have changed. The so-called predecessors heavy powder, today’s heavyweights, said that Mei Ziqing is extremely valuable today. At present, the museum has not seen the legendary Meizi Qinglongquan porcelain. The Longquan kiln celadon in the Northern Song Dynasty mainly imitated the kiln, which basically used the technique of carving flowers. The fetus bones are mostly gray, and the glaze color is mostly Ai Yeqing or slightly yellowish color. The transparency and brightness are poor, and the sculpt is more clear. This method of expression reflects the rhythm and rhythm of the engraving through the priority of the knife, thus giving the artistic charm of the scribing pattern. Common patterns include lotus petals, lotus leaves and so on. There are furnaces, bottles, plates, slag buckets and statues, and there are many styles of various style changes. Such as bottles of plum bottles, dragon and tiger bottles, five-tube bottles, bile bottles, goose gallbladder bottles, etc.; furnaces have three-legged, four-legged and eight-hearted stoves, oyster furnaces. The main changes in the celadon craftsmanship of the Southern Song Dynasty Longquan Dyna Drum Drums in the Southern Song Dynasty was the thick glaze of the thin tires. The decorative technique replaced the engraving and drawing methods by means of printing, affixing and stacking. The thickness is increased on the fetal bone without damaging the embryo body, and after the convex pattern is glazed, the glaze flows when it is fired at a high temperature, so that the convex portion of the pattern becomes more clear. The most typical utensil is the lotus petal bowl. The outer wall of the bowl is the lotus petal pattern, which is a deep-engraved lotus petal pattern. At that time, the human dragonfly “Longquan kiln.. Cui shallow white marks are true”; the middle of the lotus petal The bulge, after the firing, reveals a white line, usually called “stretching”, which not only enhances the beauty of the object, but also makes the celadon glaze appear a change. It has also become a key point in identifying Longquan kiln.
