Problems solved by technology

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.
