The main characteristics of Jun porcelain?

I. The main features of Song dynasty folk kilns Jun porcelain 1, tire color. Observed by the truncated surface of the ceramic piece, Song Minjun tire color is earth gray, darker black, lighter white, fine soil, good sintering, very few trachoma porosity, tire and glaze are applied between a very thin layer of white make-up soil, repair tire thin and uniform. （Glaze color. The glaze color of Song Minjun is mainly azure and moonlight white, with a slightly lighter greenish gray and a slightly deeper greenish blue, and the glaze is thicker, generally about 0.1 cm. The glaze is even and clean, soft and smooth when stroked. High magnification can be seen in the glaze air bubbles dense, the surface of the large, deep small. Because of the kiln changes generated by the purple-red spot irregular, color glaze thickness varies, even with a spot on the also have more changes, thick such as purple-blue, light like peach red. Green and red two-color fusion of natural, sunk into the glaze, so it looks more subtle, like a layer of mist over the red spot, in most of the blue glaze or moonlight white glaze color, especially charming. (As shown) 3, to the bowl, for example, the foot cut for the inner foot slightly outward slanting cut, the outer vertical cut, the root of the foot flat cut, after cutting the width of about 0.5 cm or so, the foot of the paste-colored tire protection glaze, glaze and glaze on the bottom of the foot body glaze consistent with the foot of the shallower and larger plate or wash, the bottom of the glaze are left on the pea-sized pegs marks. (As shown) 4, the bowl mouth along the repair tire is thin, there is a sense of sharp edges, so the mouth or flute corner of the parts of the glaze water flow and gray or gray-yellow, the edge of the circle and then down into the gradual change into azure, to the feet and shoulders of the glaze is thicker. (As shown in the figure) Second, the main characteristics of the Yuan dynasty folk kilns Jun porcelain 1, tire color. Yuan Minjun porcelain tire color by section observation is mostly dark gray, or even black-gray. According to the literature and the physical information I have on hand, the kilns in the area of Juntai in Yuxian County, Henan Province, fired at high temperatures, basically dark gray or gray, while the kilns in Shanxi, Hebei, and Hebi in Linxian County, northern Henan Province, fired Jun porcelain tires are mostly off-white or grayish-yellow, with a slightly thicker clay, more voids after sintering, and white chemical soil applied between the tire and the glaze. （The glaze color is mainly azure or moonlight white, while other whitish, bluish, blackish, purple, and reddish glazes are also found. The glaze is a little thin, generally about 0.07 centimeters. Glaze orange peel lines obvious. Visible to the naked eye in the glaze bubbles large and sparse as well as traces of glaze water flow. Some of them have become oil drops or rabbit hair lines. Kiln-variation glaze red spot more floating, bright colors, red and green almost do not blend, looks more mechanical and dull, like artificial paste painting. (As shown) 3, bowl artifacts foot wider and thicker, both inside and outside are not glazed, cutting for the inner side of the outward diagonal cut, the outer side of the vertical cut, the root of the foot after the flat cut inside high outside low, digging the foot after the center of the foot to leave a clear papillae marks, papillae can be seen around the sparsely spaced spinning pattern. The cross-section of the foot is eight-shaped. (As shown in the picture) 4, bowls thicker mouth edge, into a rounded and smooth, because of the pendant glaze is light gray, brownish gray or brownish yellow broadband edge. Tire repair sloppy, tire green thick. Glaze is not in the end, near the foot of the exposed tire, exposed tire above a thicker accumulation of glaze marks, more than one side is more significant.
