Embodiment Construction
[0033] The preparation method of jade face pottery of the present invention, comprises the following steps:
[0034] (1) Preparation of clay raw materials: uniformly mix 50% by weight ordinary clay and 50% by weight kaolin and pass through a 50-mesh sieve; the raw material for pottery production is clay, which is widely distributed in my country. The temperature of the pottery is only between 700 and 900°C, so the hardness of the pottery is not high. More importantly, the clay particles are larger and the sand content is high. The pottery produced has a low density and poor finish. Therefore, the material of jade surface pottery is mixed mud. The ratio of mixed mud is 50% of ordinary clay and 50% of kaolin for porcelain production. After mixing, its chemical composition is SIO 2 46%, AI 2 o 3 39%, H 2 O14%, and a small amount of KO 2 , Fe 2 o 3 , MO, etc. The particle size is below 3um, the hardness is close to 1 degree on the Mohs scale, and the specific gravity is 2.6,...

Abstract
The invention discloses a method for preparing a pottery with a jade surface. The method comprises the following steps of (1) argil raw material preparation; (2) fine clay preparation; (3) preparation of a greenware with the jade surface; (4) wet greenware body decoration; (5) dry greenware body decoration; (6) low temperature hardening and firing; (7) pottery body decoration and scribing creation after the low temperature hardening and firing; (8) high temperature firing; (9) three-time polishing and burnishing; and (10) finished product obtaining. The method for preparing the pottery with the jade surface, disclosed by the invention, has the advantages that the conventional production processes of potteries are changed but the basic properties of the potteries are not changed; the obtained pottery with the jade surface still has the characteristics of opaqueness, micropore breathability and water absorbability of the potteries; the important changes are that (1) the pottery hardness is increased and the Mohs hardness is up to 6.0-6.5, (2) the pottery density is increased to 2.65 and (3) the surface smoothness of the pottery is up to more than Hamiltonian 10; through the three important changes, the beating resisting ability of the pottery is increased, the artistic expression of the pottery is increased and the durability is increased.
Description
technical field [0001] The invention discloses a method for preparing jade face pottery. Background technique [0002] Pottery refers to the items made of clay as the base, processed by hand kneading, wheel making, molding and other methods, and then baked at a high temperature of 800-100 °C. The baked body is opaque and water-absorbent, and the sound of knocking is not clear. Pottery can be divided into fine pottery and coarse pottery, white or colored, unglazed or glazed; varieties include gray pottery, red pottery, white pottery, painted pottery and black pottery. The invention of pottery is an important process of human civilization and an important symbol of human development. It is the first time that human beings use natural objects to create a brand-new thing according to their own will. The ancient Chinese ancestors mastered the technology of pottery making at least 10,000 years ago, and they have been constantly summarizing and improving through long-term life pr...
