Fermentation manufacturing method for porous ceramic and porcelain raw materials

The invention relates to a fermentation manufacturing method for porous ceramic and porcelain raw materials. Yeast old dough is added into ceramic clay and porcelain clay according to a set proportion so as to obtain fermented ceramic and porcelain raw materials, and the fired finished product has an effect that pores are naturally distributed in a sparse way. The ceramic clay and the porcelain clay are fully and uniformly stirred after the yeast old dough is added. The proportion of the added yeast old dough is determined on the basis of the requirement of the finished product on the pores. The semi-finished product prepared by the fermented ceramic clay and the porcelain clay is conveyed to a kiln, and the fired finished product is in a state that the pores are naturally distributed in a sparse way. The invention provides a fermentation manufacturing method of porous ceramic and porcelain raw materials for firing ceramic and porcelain products with an effect that the pores are naturally distributed in a spa
