Problems solved by technology

Due to the cumbersome process of filling mud in Nixing pottery, and the filling mud and the body of Nixing pottery do not absorb each other during the firing process, it is very easy to fall off, and the yield of finished products is extremely low, only about 20%, which seriously hinders the production of Nixing pottery in Qinzhou. Development of Xingpottery Filling Technology

Abstract

The invention discloses a method for preventing filler of Nixing pottery from disengaging and cracking. The method comprises the steps of blank preparing, blank forming, drawing, carving, filler filling, drying and firing; for the filler filling step, a carved groove is evenly scattered with a layer of alumina powder, and then the carved groove is filled with filling pug; for the drying step, the blank filled with the pug is treated for 1 min to 5 min under the condition of 10 Mpa to 15 Mpa, and then natural air-drying is conducted. Compared with the prior art, according to the method for preventing the filler of the Nixing pottery from disengaging and cracking, alumina particles are added into the carved groove, the electrostatic attraction between the filled pug and a blank body can be greatly increased, and disengaging and cracking of the filled pug in the firing process can be greatly reduced.

Description

technical field [0001] The invention relates to a firing method of Nixing pottery, in particular to a method for preventing Nixing pottery filling mud from falling off and cracking. Background technique [0002] According to historical records, the mud-filling process of Nixing pottery in Qinzhou has been formed since the Qing Dynasty. The traditional mud-filling process of Nixing pottery mainly includes the following steps: 1) Preparation of blanks: The blanks are selected from the east of Qinjiang River, which crosses the urban area of ​​Qinzhou City. The soil in the area is commonly known as Dongni (soft clay with a yellowish-white color and contains a small amount of quartz sand, which plays a role in adjusting plasticity and bonding in the production process of Nixing pottery), and the soil in the west of the Qinjiang River is commonly known as Xini (contains a small amount of K 2 O, NaO, CaO, MgO, Fe 2 o 3 、TiO 2 , MnO 2 , is a kind of purple mudstone with high ir...
