Mud of firewood-fired Nixing pottery and process of making firewood-fired Nixing pottery by using the mud

Abstract

The invention provides pug of firewood-fired Nixing pottery and a process for manufacturing the Nixing pottery from the pug. The pug is prepared from, by weight, 5.5-6.8 parts of eastern mud, 1.3-2.0 parts of western mud, 1-1.5 parts of wood ash and 2-2.5 parts of kaolin. The process of for manufacturing the Nixing pottery from the pug comprises the steps of blank preparation, blank body forming, blank body drying and blank body firing; according to blank preparation, the eastern mud, the western mud, the wood ash and the kaolin with the formula amount are prepared into a blank through a conventional process; according to blank body burning, the blank body is fed into a wood-fired kiln, woody plants are adopted as fuel, the firing temperature ranges from 1,160 DEG C tot 1,180 DEG C, and after firing is completed, cooling and drawing are carried out. The kaolin and the wood ash are added into conventional Nixing pottery pug, so that the firing temperature range of the Nixing pottery is greatly widened; the melting temperature of ash of fuel wood can be reduced, the melting time of the ash can be shortened, and the fuel wood cost is greatly reduced.

Description

technical field [0001] The invention relates to a preparation method of Nixing pottery, in particular to a mud material for firewood-fired Nixing pottery and a process for making firewood-fired Nixing pottery by using the mud material. 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 ...

AI Technical Summary

Problems solved by technology

Firewood-fired Nixing pottery requires more than two days of firing time, and the firing temperature must be above 1260°C, otherwise the effect of falling ash will be poor, which will greatly increase the consumption of firewood and cause the cost of firewood-fired Nixing pottery to be relatively high. high

Not only that, the firing temperature of traditional Nixing pottery clay is relatively low, generally 1100°C to 1200°C to make pottery. At this temperature, it is difficult for wood ash to completely melt, and it is impossible to accumulate ash on the surface of the Nixing pottery body to form a glaze. Increase the firing temperature to above 1260°C, and the body of Nixing pottery will be cracked
