Abstract

The invention discloses a making method of natural crackle on surface of red stoneware ware, including the following steps: three red stoneware green-ore materials are selected, wherein the shrinkageof material (A) is 8-10%, the shrinkage of material (B) is 15-20%, and the shrinkage of material (C) is 20-25%; complexing the three materials together in inside-to-outside sequence and making original blank according to conventional manufacturing method, wherein the thickness of the inner layer material (A) is 60-70% of the total thickness of the blank body, the thickness of the immediate layer material (B) is 5-10% of the total thickness of the blank body, and the thickness of the outer layer material (C) is 20-30% of the total thickness of the blank body; carrying out three times of sintering on the made original blank, wherein the temperature of a primary sintering is 1120-1160 DEG C, the temperature of a secondary sintering is 1140-1170 DEG C, and the temperature of a third sinteringis 1170-1190 DEG C. the invention realizes crackle on surface of red stoneware ware, so that the surface of the ware forms 'spun gold iron wire' beautiful texture.
