The invention provides a preparation of tadpole texture glaze. The method comprises the steps as follows: preparing ground glaze slip; (2) preparing cover glaze slip: adding a proper amount of water to a certain part by weight of cover glaze slip for mixing, and performing ball milling to obtain the cover glaze slip with the mass concentration being 50%-60%, wherein the cover glaze slip is prepared from raw materials in parts by weight as follows: 2-6 parts of Suzhou clay, 5-8 parts of pear wood ash, 1-2 parts of barium oxide, 10-18 parts of calcite, 1-3 parts of calcined talc, 2-5 parts of copper ore, 30-46 parts of melilite and 3-7 parts of zinc oxide; (3) performing glazing; (4) performing firing at the temperature of 1,320-1,330 DEG C. Compared with the prior art, through scientific and reasonable raw material proportioning and control of the firing technology, the tadpole texture glaze with sharp color contrast, clear and regular tadpole textures and unified tadpole swimming direction can be fired, the prepared tadpole texture glaze cannot fall off easily, and the process is simple.
