[0016] Example 1

[0017] 1) Preparation of Nixing pottery clinker: Mix the east mud and the west mud in a weight ratio of 6:4, calcinate at 1100°C for 8 hours, cool, and pulverize to obtain.

[0018] 2) Preparation of the blank: The preparation of the blank is to mix the east mud and the west mud at a weight ratio of 6:4, and then add 8% of the total weight of the mixed mud and 5% potash nepheline mixed and ground. Press filter, vacuum clay mud, stale, ready blank;

[0019] 3) Blank forming: The blank is made into 100 candlestick blanks with a height of 10cm and a diameter of 3cm;

[0020] 4) Dry body: dry the body in the shade;

[0021] 5) Decorative body: decorate the body according to the hollowing process to obtain a hollow candlestick body;

[0022] 6) Green body firing: The decorated green body is further dried to a moisture content of 2%, then sent to the kiln for conventional firing, and after cooling, it is discharged out of the kiln;

[0023] 7) Polishing and polishing.

Abstract

The invention discloses a hollow-out decoration process for Nixing pottery. The hollow-out decoration process comprises steps of paste preparation, body forming, body drying, hollow-out decoration of a body and body firing, wherein for paste preparation, east clay and west clay are mixed in a weight ratio being (4-6):(6-4), Nixing pottery clinker accounting for 8%-15% of the total weight of the mixed clay material and kaliophilite accounting for 5%-10% of the total weight of the mixed clay material are added and mixed, and the paste is prepared; the Nixing pottery clinker is prepared from the east clay and the west clay through mixing and conventional firing. By adding a certain amount of clinker to the mixed clay material, shrinkage of the body can be reduced greatly, body support is enhanced, and the firing rate of finished hollow-out Nixing pottery products is increased. The diameter of formed mullite crystal nucleuses can be smaller by addition of kaliophilite, further, K2O formed through decomposition of kaliophilite at a high temperature can cause decomposition of coarse mullite crystals, so that the mullite crystals are micronized, finally, crystal phase of the finished Nixing pottery products is micronized, and the finished products are rich in luster.

Description

Technical field [0001] The invention relates to the manufacturing process of Nixing pottery, in particular to the hollow decoration process of Nixing pottery. Background technique [0002] Qinzhou Nixing pottery, Yixing Zisha pottery in Jiangsu, Jianshui pottery in Yunnan, and Rongchang pottery in Sichuan are among the four famous potteries in China and are well-known both at home and abroad. The preparation process of hollow Nixing pottery mainly includes the following steps: 1) Preparation of blanks: The blanks are selected from the clay east of the Qinjiang River in Qinzhou City, commonly known as Dongni (soft clay, yellow-white in color, and trace quartz sand , Plays the role of adjusting plasticity in the production process of Nixing pottery for combination), and the soil in the west of Qinjiang River, commonly known as Ximu (containing a small amount of K 2 O, NaO, CaO, MgO, Fe 2 0 3 , TiO 2 , MnO 2 , Is a kind of purple clay stone with high iron content, the color is purpl...
