Silicon Nitride Ceramic:
my country’s ceramic art developed into the Ming Dynasty and entered a new journey. Before the Ming Dynasty, the porcelain was mainly celadon, but after the Ming Dynasty, it was mainly white porcelain, especially blue and white. Multicolor became the main product of Ming Dynasty white porcelain. At this time, the porcelain body also tended to be thinner. The demand for fineness and whiteness, and the memorization of styles on the blank body also starts from then on. The age, hall number, and name of the person are all available, so that the research evidence has a more reliable identification. [9]
Chinese porcelain in the Qing Dynasty can be said to have reached its peak. The porcelain production technology of the early Qing Dynasty was superb, and the decoration was exquisite and gorgeous. Qing Dynasty colored porcelain had a great development on the basis of the Ming Dynasty. The craftsmanship innovation has differentiated more colors, ink, blue, and gold. It also appears on the paintings of multicolored porcelain, with its elegant colors, which enriched the porcelain decoration of the Qing Dynasty. In the production of modern pottery, the raw materials are eclectic. The combination, use, and penetration of multiple materials have produced complementary artistic effects, making modern ceramic art both rich in expressiveness and full coordination, and surface decoration and space treatment have also reached a higher level. Modern pottery art pays attention to texture and performance. It does not pay attention to rough or fine raw materials. The materials are no longer limited to porcelain clay and pottery clay, but deliberately break through the range of use of traditional ceramic materials, using the different characteristics of the clay to make use of various materials. Potential beauty, as long as the mud, sand and Other Materials that can be burned by the kiln can be used to serve it.
