The invention provides a method for producing a base coat being matched with a blank and having an excellent glazing effect and relates to the technical field of building materials. Materials are selected within a preset component scope of the base coat and the technology is standardized. The method comprises the following steps: mixing roasted kaolin, quartz, potash feldspar, soda feldspar, calcite, steatite, dolomite, zinc oxide, zircon powder and nepheline, which are less than 100 meshes and are 2-30kg, thereby obtaining the raw materials of the base coat; adding thickening agents, water reducing agents and a right amount of water into the raw materials of the base coat, wherein the thickening agents and the water reducing agents are both 0.3-0.5% of the raw materials of the base coat; and putting into a ball mill, thereby milling into a slurry base coat end product, wherein the end product comprises the following chemical components: 40-60% of SiO2, 15-25% of Al2O3, 5-15% of CaO, 0-8% of MgO, 2-10% of K2O+Na2O, 0-8% of ZnO, 3-12% of ZrO3, 0-2% of thickening agents and water reducing agents, and the fineness is 0.4-0.5% of ten-thousand hole screening. The method is used for producing the base coat. The base coat is matched with the blank and is excellent in glazing effect.
