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 ...

Embodiment 1

[0019] 1) Prepare the blank: mix 5.5 parts of Dongni, 1.3 parts of Xini, 1 part of ashes from burning Paulownia branches and / or leaves, and 2 parts of high white mud, and make a blank through a series of processes such as grinding and dehydration;

[0020] 2) Body molding: the blank is made into various types of green bodies by plastic method or grouting method;

[0021] 3) Trim the green body: trim the green body to meet the design requirements;

[0022] 4) drying: adopt air-drying method to dry green body, make green body water get rid of;

[0023] 5) Firing the green body: put the dried green body into a firewood kiln, use Paulownia branches and / or leaves as fuel, heat up to 1180°C at a heating rate of 60°C, stop heating, and leave the kiln after natural cooling.

Embodiment 2

[0025] 1) Preparation of blanks: Mix 6.8 parts of eastern mud, 2.0 parts of western mud, 1.5 parts of ashes from burning citrus branches or leaves, and 2.5 parts of high white mud, and make blanks through a series of processes such as grinding and dehydration;

[0026] 2) Body molding: the blank is made into various types of green bodies by plastic method or grouting method;

[0027] 3) Trim the green body: trim the green body to meet the design requirements;

[0028] 4) drying: adopt air-drying method to dry green body, make green body water get rid of;

[0029] 5) Firing the green body: put the dried green body into a firewood kiln, use citrus branches or leaves as fuel, heat up to 1175°C at a heating rate of 80°C, stop heating, and leave the kiln after natural cooling.

Embodiment 3

[0031] 1) Prepare the blank: mix 5.6 parts of eastern mud, 1.3 parts of western mud, 1 part of ashes from burning pine branches and / or leaves, and 2.1 parts of high white mud, and make a blank through a series of processes such as grinding and dehydration;

[0032] 2) Body molding: the blank is made into various types of green bodies by plastic method or grouting method;

[0033] 3) Trim the green body: trim the green body to meet the design requirements;

[0034] 4) drying: adopt air-drying method to dry green body, make green body water get rid of;

[0035] 5) Firing the green body: put the dried green body into a firewood kiln, use pine branches and / or leaves as fuel, first raise the temperature to 450°C at a rate of 80°C per hour, and then increase the temperature at a rate of 80°C per hour. Raise the temperature to 900°C at a heating rate of 150°C, and then raise the temperature to 1160°C at a heating rate of 120°C per hour, stop heating, and leave the kiln after natural...
