Problems solved by technology

However, the chemical composition of the Nixing pottery body and Jun glaze is quite different, and the Jun glaze is not compatible with the body. The thickness of the middle layer of the body glaze formed is only 15-20 μm, and the middle layer is loose, consisting of a large number of pores and large pores. Particles are very prone to defects such as deformation, cracking, deglazing, and glaze absorption

Embodiment 1

[0026] 1) After drying 100 Nixing pottery teapot blanks with a diameter of 15 cm made by the conventional method, apply a layer of low-temperature glaze with a thickness of 0.5 mm on the surface of the blank; the low-temperature glaze is made of the following raw materials in parts by weight : 50 parts of quartz, 6 parts of calcite, 8 parts of borax, 8 parts of feldspar, 2 parts of spodumene, 3 parts of cordierite, 1 part of copper oxide, 3 parts of zinc oxide, 2 parts of Dongni, 1 part of Xini;

[0027] 2) Send the decorated green body into the kiln, and gradually increase the temperature, first raise the temperature to 500°C at a rate of 80°C per hour, and then increase the temperature at a rate of 200°C per hour. The temperature is raised to 900°C, kept at this temperature for 1 hour, and then raised to 1000°C at a rate of 100°C per hour, kept at this temperature for 3 hours, cooled and then taken out of the kiln to obtain Nixing Jun pottery.

Abstract

The invention provides a preparation process of Nixing Jun pottery, which includes preparing a blank, molding the blank, drying the blank, decorating the blank and firing the blank. The decoration of the blank is to apply a layer of low-temperature Glaze; the low-temperature glaze is made of 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, cordierite 3 to 5 parts, 1 to 3 parts of copper oxide, 3 to 5 parts of zinc oxide, 2 to 3 parts of Dongni, and 1 to 2 parts of Xini. The sintering temperature of the glaze of the present invention is compatible with the green body, and the expansion coefficient is slightly lower than that of the green body, which can effectively avoid glaze cracking, deglazing and other phenomena. The three-stage firing process can also effectively promote the formation of the intermediate layer of the blank glaze, increase its thickness and density, and make the blank glaze tightly bonded, thereby avoiding defects such as glaze cracking and deglazing.

Description

technical field [0001] The invention relates to a preparation process of Nixing pottery, in particular to a preparation process of Nixing Jun pottery. Background technique [0002] The preparation process of Nixing pottery in Qinzhou mainly includes the following steps: 1) Preparation of blanks: The blanks are made of pottery clay materials, and the unique East and West clay in Qinzhou are selected as raw materials. The Dongni is the soil in the area east of the Qinjiang River across the urban area of ​​Qinzhou City, mostly in low-lying areas. The soil is dense and soft, soft clay, yellow-white in color, and contains a small amount of quartz sand. Xini is the soil in the area west of the Qinjiang River that crosses the urban area of ​​Qinzhou City. The storage area is mainly on hillsides. 2 O, Na 2 O, CaO, MgO, Fe 2 o 3 、TiO 2 , SiO 2 , MnO 2 , is a kind of purple mudstone with high iron content, the color is purple red, and the surface layer has a small amount of iro...
