Technical Field

The invention belongs to the technical field of modern ceramic preparation, and particularly relates to a jade vitreous glaze and a glazing method.

Background

China has a long history and brilliant history and unique achievements around the world, is a bright and civilized witnesses of China, porcelain is obtained by removing porcelain, the porcelain can be classified according to the characteristics, materials, production places, processes and the like of the porcelain, and China has more than 25 kinds of porcelain at present if the porcelain is classified according to the kilneye of the porcelain. The glaze color is also an important standard for classifying porcelain, is divided into two categories of single-color glaze and colored glaze porcelain, and goes through the process from single-color glaze to multi-color glaze (colored glaze) in the development of ceramics. The single-color glaze includes green glaze (pink, azure, bean, etc.), white glaze (sweet white, bluish white), red glaze (common vegetable red, red bovine hemoglobin, cowpea red, etc.), blue glaze, yellow glaze, green glaze, black glaze, etc. The multicolor glaze is divided into two types: the first is glaze composed of color blocks with different glaze colors and shapes; the other is the glaze decoration drawing pattern commonly called as 'colored porcelain'. The color porcelain is divided into overglaze color, underglaze color and double-layer sandwich color according to the glazing mode.

The modern ceramics is made up by using mineral raw material or chemical raw material according to a designed proportion and making them into glaze slurry, applying it on the surface of porcelain blank body and calcining so as to make the porcelain implement possess lustrous and form, and can produce artistic quality. The glaze used in modern porcelain is divided into lime glaze and feldspar glaze. The lime glaze is prepared from glaze and lime (the main component of which is calcium oxide) which are natural mineral raw materials similar to porcelain stone; the feldspar glaze is prepared from quartz, feldspar, talc, kaolin, etc. by mixing at a certain proportion. The glaze color is that metal oxide is added into lime glaze and feldspar glaze or other chemical components are infiltrated into the lime glaze and the feldspar glaze, and the components of the glaze mixture and the preparation process are different to form colorful ceramic glaze color.

The five famous china porcelains are Ru porcelains which are the chief names in China, and agate is used as glaze, so that the glaze is moist, soft, mild, simple and elegant, the glaze is like piled butter, bright, translucent and pure, the glaze is like jade, the glaze is like silk, and the grain pieces are glittering and translucent like cicada wings. Some glazes are covered with red halos, some appear as morning sea, some appear as sunset, some appear as rainy day and fine, and some appear as long rainbow and hang in the air. Observed with a magnifying glass, loose bubbles of flamboyant brown under glaze, opaque glaze or crystalline glaze can be seen. The modern Ru glaze is prepared by grinding and mixing agate with feldspar glaze mineral raw materials and chemical raw materials according to a certain proportion. After the glaze is doped with agate, the reaction is complex, the firing process is extremely difficult to control, the yield is too low, and a perfect Ru porcelain with an excellent quality is difficult to be produced by a plurality of kilns. The ancient skills and the fire are transmitted, the people can find out the essence from the soil, and a large number of current Ru porcelain workers still study and develop the technology.
