The invention discloses a black glaze heat-resistant ceramic pot. The black glaze heat-resistant ceramic pot comprises a ceramic pot blank and black glaze. The ceramic pot blank comprises the following base material components: petalite 30-40%, kaolin 20-40%, clay 10-30%, aluminium oxide 5-10%, alkaline earth 5-10% and high-solubility quartz 5-15%. The black glaze comprises the following base material components: spodumene 5-15%, petalite 45-60%, petalite 5-10%, kaolin 5-12%, quartz 5-10%, oxide 2-3%, useless porcelain powder 5-10%, a colorant 7-12%, calcium carbonate 1-3%, barium carbonate 0.5-2% and calcite 3-5%. The invention further provides a preparation method of the black glaze heat-resistant ceramic pot. The oxide is added in glaze, the glossy of a glaze surface is improved, the opacity of the glaze is improved, the refractive index of glaze to light is increased, the useless porcelain powder is added, resources are recycled, furthermore, air pores and needle holes in the glazesurface are reduced, the quality of the glaze surface is improved, the ratio in pigment is strictly controlled, and the manufactured ceramic pot is bright in color, high in coloring degree and worthyof being popularized widely.
