Embodiment Construction

[0033] The preparation method of jade surface pottery of the present invention includes the following steps:

[0034] (1) Preparation of pottery clay materials: mix 50% by weight of ordinary clay and 50% by weight of kaolin, and then pass through a 50-mesh sieve; the raw material for pottery production is clay, which is widely distributed in my country. Because clay is not resistant to high temperatures, it is fired The temperature is only between 700-900℃, so the hardness of the pottery is not high. More importantly, the pottery clay has large particles, high sand content, low density and poor finish. Therefore, the material of jade surface pottery is mixed clay. The proportion of mixed clay is 50% ordinary clay and 50% kaolin used 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 Mohs, and the specific gravity is...

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 is a method for preparing jade surface pottery. Background technique [0002] Pottery refers to items made from clay as a tire, processed by hand kneading, wheeling, molding and other methods, and then baked at a high temperature of 800-100°C. The baking body is opaque and absorbent, and the sound of tapping is unclear. Pottery can be divided into fine pottery and rough 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 humans have created a brand-new thing using natural objects according to their own will. The ancestors of ancient China mastered the technique of pottery at least 10,000 years ago, and they kept summing up and improving in long-term life practice. Therefore, in terms of production technology, ut...
