Abstract

The invention discloses a manufacturing process of iron oxide red transmutation glazed porcelain. The iron oxide red transmutation glazed porcelain comprises a green body and an iron oxide red glaze,wherein the green body is prepared from the following raw materials: Dehua feldspar, Dehua quartz, Dehua kaolin, sillimanite, szaibelyite, boehmite, sphalerite, zinc oxide and zirconium oxide. By limiting the composition of the green body and improving the basic formula of the glaze, a plurality of orange plaques with the sizes of broad beans and peas are distributed on the glaze surface of the fired iron oxide red transmutation glazed porcelain.

Description

technical field [0001] The invention belongs to the field of porcelain preparation, and in particular relates to a manufacturing process of iron red kiln glazed porcelain. Background technique [0002] With the rapid development of the economy and society, people's quality of life is improving day by day, and the concept of consumption is also constantly changing, requiring that ceramic products should not only be practical, but also artistic and ornamental. The existing glaze color can be divided into high temperature glaze and low temperature glaze according to the firing temperature; according to the appearance characteristics, it can be divided into transparent glaze, opacity glaze, color glaze, glossy glaze, matte glaze, crackle glaze (open sheet), crystal glaze and so on. [0003] The iron-based crystalline glaze began to be fired in the Song Dynasty, and formed a characteristic tea set decoration. It was famous at that time. There were varieties such as oil drop, rabb...
