Purple sand is hard and fine in texture and quiet in color, but it does not have the translucency of porcelain body. The colorant of purple sand is mainly iron oxide contained in purple sand mud. Purple sand is fired in an oxidizing atmosphere. If the forming temperature is too high, it will cause easy cracking, rough surface, no air permeability, and lose the original characteristics of purple sand products.
[0003] The glaze surface of Dehua white porcelain is bright, the texture is firm and dense, crystal clear like jade, and the glaze surface is moist like fat, so it has the reputation of "ivory white", "lard white" and "velvet white". The firing temperature is 1250°C to 1400°C. If the firing temperature is too low, the color will decrease.

Abstract
The invention relates to a Dehua white porcelain and purple sand combined ceramic product and a preparation process of a porous material. The Dehua white porcelain and purple sand combined ceramic product includes a purple sand blank material and a white porcelain blank material. According to the Dehua white porcelain and purple sand combined ceramic product, through selection of blank material raw materials and modification of a firing process, the beautiful stereo particle feeling of traditional purple sand is retained, the characteristics of glittering and translucent and moisture glaze of the Dehua white porcelain are also retained, the Dehua white porcelain and the traditional purple sand are combined, an obvious contrast is formed, and the Dehua white porcelain and the purple sand are mutually supported to form a new ceramic product. The invention provides the firing process of the Dehua white porcelain and purple sand combined ceramic product; the fired product has good quality and high rate of finished products, and the Dehua white porcelain and purple sand combined ceramic product not only can meet the needs of consumers but also can improve the economic benefits and market competitiveness, and has positive significance for promoting the development of the Dehua white porcelain and the purple sand.
Description
technical field [0001] The invention belongs to the field of ceramic products. Specifically, the invention relates to a ceramic product combined with Dehua white porcelain and purple sand and a preparation process. Background technique [0002] Zisha is a kind of ceramic product between pottery and porcelain. Zisha products can be in sky blue, chestnut, dark liver, pear skin, beige, cinnabar purple, begonia red, blue gray, dark green and other colors. Thin, under the delicate appearance, you can still see the beautiful three-dimensional particle feeling. Purple sand is hard and fine in texture and quiet in color, but it does not have the translucency of porcelain body. The colorant of purple sand is mainly iron oxide contained in purple sand mud. Purple sand is fired in an oxidizing atmosphere. If the temperature is too high, it will easily crack, the surface will be rough, there will be no air permeability, and the original characteristics of purple sand products will be l...
