Abstract

The invention provides a preparation method of black purple sand pug. The preparation method comprises the following steps: selecting purple sand shale as the raw material ore, weathering the raw material ore by drying or air-drying, drenching or soaking the weathered raw material ore by using clear water, standing, aging the raw material ore by drying or air-drying, and repeating the process for 3 times to 5 times; crushing into 60-mesh particles or 150-mesh powder, mixing and stirring the particles or the powder with 300-mesh slurry, sealing for aging and stirring thoroughly; pressing into clay bars, sealing for aging, repeatedly pressing the clay bars and sealing for aging for 3 times to 5 times to obtain the black purple sand pug. The black purple sand pug produced by the method provided by the invention is good in quality and not easy to crack while being used for firing purple sand products, and the products obtained are good in quality; besides, the produced purple sand products are more natural in texture, good in transmission of light and water color, excellent in color generation and fine in touch feeling.

Description

technical field [0001] The invention relates to a preparation method of black purple sand mud. Background technique [0002] Zisha pottery is a kind of stoneware, which is a ceramic product between pottery and porcelain. It has the characteristics of compact structure, high strength, thermal shock resistance and good air permeability. A traditional culture that people love. The purple sand ore used for firing purple sand pottery is iron-bearing clayey siltstone, which is composed of hydromica and kaolin, quartz, mica chips and iron and other mineral components. The main chemical components are silicon oxide, aluminum oxide, iron oxide, oxide Calcium, magnesium oxide, manganese oxide, potassium oxide and sodium oxide, etc., have a variety of colors, and are mainly divided into red purple sand, white purple sand, yellow purple sand, purple sand, green purple sand, and black purple sand. Among them, the source of black purple sand is very rare. Ore soil of precious purple san...
