The invention provides a process for preparing Nixing Jun pottery. The process comprises the steps of blank preparation, blank molding, blank drying, blank decoration and blank burning, wherein a layer of low-temperature glaze is applied to the dried blank in the blank decoration step; and the low-temperature glaze is prepared from the following raw materials in parts by weight: 50-60 parts of quartz, 6-10 parts of calcite, 8-15 parts of borax, 8-12 parts of feldspar, 2-5 parts of spodumene, 3-5 parts of cordierite, 1-3 parts of copper oxide, 3-5 parts of zinc oxide, 2-3 parts of Dong clay and 1-2 parts of Xi clay. According to the process, the glaze has a sintering temperature adaptive to that of the blank and an expansion coefficient slightly lower than that of the blank, so that glaze cracking, occurrence of glaze peeling and other phenomena can be effectively avoided; and formation of an intermediate layer between the glaze and the blank can be effectively promoted by a three-section sintering process, the thickness and compactness of the pottery can be increased, the blank and the glaze are tightly combined, and thus glaze cracking, glaze peeling and other defects can be avoided.
