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 manufacturing process for filling a Nixing pottery green body with white clay. The manufacturing process comprises the steps of preform body preparation, green body forming, painting, engraving, clay filling, drying and firing; in the clay filling step, a layer of ferric oxide powder and a layer of amphoteric starch are uniformly sprayed in engraved grooves, and then the engraved grooves are filled with the white clay; the white clay is formed by mixing eastern clay and western clay according to the weight ratio of (7-8):(2-3) and then processing the mixture according to the manufacturing process of a preform body; in the drying step, the green body filled with the clay is processed for 1-5 min under the condition of 10-15 Mpa and then aired naturally. By adding ferric oxide particles, electrostatic attraction between the white clay and the green body can be greatly enhanced; molecular long chains of the amphoteric starch have intertwining and cross-linking functions, so that the white clay and the preform body are tightly combined, certain water retention uniformity is also achieved, dewatering is more uniform, and neither cracking nor falling occurs.

Description

technical field [0001] The invention relates to a manufacturing method of Nixing pottery, in particular to a manufacturing method of filling white mud on a body of Nixing pottery. 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 0 3 、TiO 2 , MnO 2 , is a kind of purple mudstone with high iron...
