[0073] Example 1: A kind of purple sand green mud processing and firing method using natural pottery clay as raw material

[0074] This example uses natural clay as raw material without adding any chemical raw materials and artificial pigments, and uses dry method + wet method to process the purple sand green clay with particle sizes of -20 mesh, -40 mesh, -60 mesh, -80 mesh, and -100 mesh respectively. , using the optimized process to burn green clay purple sand, the processing and firing process is carried out according to the following 9 steps:

[0075] (1) Selection of pottery clay: select soil-agglomerate natural pottery ore, whose chemical composition is w(SiO 2 )50%~70%, w(Al 2 o 3 )22%~33%, w(Fe 2 o 3 )1%~3%, w(K 2 O)1%~4%, w(CaO)<1%;

[0076] (2) Drying and crushing: After the pottery clay is naturally dried, crushing equipment is used to process the pottery clay into powdery materials;

[0077] (3) Material screening: Use screening equipment to pass all the po...

Abstract

The invention relates to a processing and firing method of purple clay green mud with natural pottery clay as a raw material without addition of any chemical raw materials and artificial pigments. The method includes the steps of: 1) selecting earthy-block mass pottery clay, of which w(SiO2) is 50-70%, w(Al2O3) is 22-33%, w(Fe2O3) is 1-3%, w(K2O) is 1-4% and w(CaO) is less than 1%; 2) crushing the raw material; 3) sieving all of the crushed material through a standard sieve at corresponding mesh number; 4) removing mechanical iron and iron ore granules through magnetic separation; 5) adding 16-20% by weight of water to wet the material and completely stirring the materials uniformly; 6) performing vacuum pugging and performing sealed aging for more than 30 days; 7) and 8) manufacturing a vessel and drying the vessel; and 9) firing the vessel according to an optimized process to prepare a purple clay green mud product which has a slight-yellow to slight-yellow and green color. The method has significant effects, good safety and simple process, is easy to promote and has wide applications, and has significant economic and social benefits.

Description

[0001] 1. Technical field [0002] The invention relates to the field of purple sand mud processing and production, in particular to the processing and production of purple sand green mud using natural pottery clay as a raw material. [0003] 2. Background technology [0004] Zisha pottery, referred to as Zisha, is a kind of ceramic product with traditional Chinese characteristics, especially Yixing Zisha is the most famous. Zisha integrates practicality, functionality, appreciation, artistry and collection, and is deeply loved by people. In recent years, with the continuous development of tea culture, the continuous expansion of the use of purple sand, and the continuous improvement of purple sand collections, purple sand products, especially purple sand teapots, have attracted more and more attention from the world. [0005] Zisha is made by firing purple sand mud, and purple sand mud is processed from purple sand ore. The fundamental reason for the emergence and developmen...
