The invention belongs to a ceramic preparation method, and in particular relates to a preparation method of a Dong green glaze for ceramic bases. The preparation method comprises the following steps: (1) applying a priming glaze and a cover glaze with a glaze soaking method in sequence on an ungiazed ceramic base blank, wherein the total glaze thickness of a glaze layer is controlled to be 0.8-1 mm; after the glaze is dried, entering a roller kiln for burning, wherein the burning temperature is 1180-1200 DEG C, and the burning period lasts for 5 hours; the priming glaze consists of feldspar, boron clinkers, calcite, quartz, suzhou clay, ore produced in lakebed of Lake Taihu, zinc oxide and manganese oxide, and the cover glaze consists of boron clinkers, lithium feldspar, quartz, calcined talc, suzhou clay, calcite, sodium carbonate, copper oxide, cobalt oxide and nickel oxide. According to the preparation method of the Dong green glaze for the ceramic bases provided by the invention, the Dong green glaze is burnt through the roller kiln after decoration on the ceramic bases by adopting a specific glaze formula aiming at the characteristics of ceramic products, so that a high-grade and high-quality glaze effect is obtained.
