Preparation method of Zisha mineral yellow gold clay

Abstract

The invention relates to a preparation method of Zisha mineral yellow gold clay. Mineral yellow raw ore scattered on a tender clay ore seam is selected manually, and stacked in the open air for natural weathering in winter and summer; the weathered raw ore is dried in the air and milled by a hard stone mill into 60-mesh and 80-mesh powder and 120-mesh fine powder, water is added, and sealing and aging are performed after uniform mixing and stirring; vacuum clay refining, clay strip pressing, sealing and aging are performed repeatedly 3-6 times, and the Zisha mineral yellow gold clay is prepared. The clay prepared with the method is original and pure without any chemical raw materials or artificial pigments, and is not easy to crack when a Zisha earthenware product is fired; the prepared Zisha earthenware product not only is natural and environmentally friendly, but also has excellent quality, natural texture, delicate handfeel and good light transmittance, water color and color appearance; the purpose of changing waste materials of Zisha ore into valuable materials is also achieved.

Description

technical field [0001] The invention relates to the technical field of purple sand pottery raw materials, in particular to a preparation method of purple sand stone gold mud. Background technique [0002] The raw material of Zisha pottery is a kind of hydrous aluminosilicate mineral clay, which is formed by long-term weathering and geological processes of feldspar-containing rocks in the earth's crust. It is widely distributed in nature and has a wide variety. It is stored in most areas of my country Rich, his main components are silicon dioxide, aluminum oxide, ferric oxide, manganese dioxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, titanium oxide and crystal water. There are many kinds of mud materials for purple sand pottery. Apart from the main red mud, purple sand mud, and green mud, there are also various colors such as white mud, black mud, yellow mud, and pine flower mud. Zisha pottery is not glazed, but fully utilized. The natural color of cla...

Problems solved by technology

[0003] At present, there are few high-grade purple sand raw materials, especially because of the random mining of purple sand mineral resources in the past, which seriously damaged the rational use of mineral resources, and purple sand mineral resources are becoming more and more scarce. Mining is restricted and protected. At present, most of the common purple sand products on the market are almost made of low-quality purple sand raw materials or purple sand tailings raw materials plus chemical raw materials, which not only endangers the health of the body, but also seriously affects the application and development prospects of purple sand pottery.
