Processing and firing method of purple clay green mud with natural pottery clay as raw material

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...
