The present invention provides a porcelain formula and a manufacturing process. The porcelain manufacturing process comprises: grinding and mixing raw material components of Longyan clay, bone charcoal, talcum, clay, Mingling mud, sepiolite, Enzhou rare stone powder, feldspar, calcite, flint clay and mineral wool according to a ratio in parts by weight; performing shaping according to a design, trimming a green body, drying the green body, firing the green body in a non-glazing manner at a low temperature of 800 DEG C to 850 DEG C in a reducing atmosphere with 3%-5% CO, and performing polishing for smoothness; and glazing the green body, adding Huiqing, heating and firing the product at 1200 DEG C to 1250 DEG C in a reducing atmosphere with 6%-8% CO. The porcelain provided by the present invention is firm in bonding of raw material components, has an average shaping rate greater than 96%, and is good in whiteness and glaze glossiness. Cracks are effectively prevented, and meanwhile, the blister and deformation phenomena caused by talcum in the porcelain formula are eliminated. In addition, the firing temperature of the porcelain manufacturing process is lowered.
