Making method of natural crackle on surface of red stoneware ware

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.

Description

technical field [0001] The invention relates to a method for manufacturing a purple sand vessel, in particular to a method for manufacturing a purple sand vessel whose surface is naturally sliced. Background technique [0002] The surface of ceramic handicrafts begins with Song Ge kiln. Ge kiln is a unique product made by utilizing the different shrinkage rates of glaze and body during the firing and cooling process of ceramic products, and the glaze cracks into irregular textures. Glaze cracks, commonly known as cracks; glaze crack lines have both rough black lines and yellow and red fine lines, which are called "gold wires and iron lines". This kind of Ge kiln porcelain with cracks is very unique and beautiful. [0003] Zisha handicrafts, which are as famous as ceramics, have always been a difficult problem how to present cracked lines on the surface of purple sand vessels without losing the simple charm of purple sand vessels. Because purple sand vessels are made direct...

Problems solved by technology

Because purple sand vessels are made directly from the mined purple sand raw mud ore, and then fired, the surface of the body is not glazed. To form the style of "golden wire and iron wire", only the surface of the body of the purple sand vessel can be formed. Slight cracks occur, and the temperature control requirements are very high during firing; and because the various components in the purple sand raw ore slime are not fixed, when the temperature is too high during firing, the surface of the low body does not crack, and the temperature is too high, the surface of the body The pieces are easy to fall off; the temperature is too low, resulting in no pieces on the surface of the green body, and the style of "golden wire and iron wire" cannot be formed
