Embodiment 1

[0034] Take 60 parts of Dongni and 40 parts of Xini to make blanks, and after the blanks are formed, trimmed and dried, the blanks are fired.

[0035] Firing the green body: first put the dried green body into a kiln with a volume of 5 cubic meters, place 200 teapots, and gradually increase the temperature, first at a heating rate of 110°C per hour , after rising to 500°C, then increase the temperature at a rate of 150°C per hour until it rises to 1150°C, and continue firing at this temperature for 0.5 hours; put 10kg of ignited kiln-changing materials from the holes of the kiln at multiple points Put it into the kiln, including 2 parts of pine branches, 2 parts of raw leaves, 3 parts of wood chips, 2 parts of coal, and 3 parts of turpentine; then continue firing at 1200 ° C for 0.5 hours, and gradually reduce the temperature in the kiln to 1100 ° C. At ℃, put in 5 kg of kiln materials again, including 2 parts of pine branches, 2 parts of raw leaves, 3 parts of sawdust, 2 part...

Embodiment 2

[0037] Take 50 parts of Dongni and 50 parts of Xini to make blanks, and after the blanks are formed, trimmed and dried, the blanks are fired.

[0038] Firing the green body: first put the dried green body into a kiln with a volume of 1 cubic meter and 200 teapots, and gradually increase the temperature, first at a heating rate of 120°C per hour , after rising to 450°C, then increase the temperature at a rate of 130°C per hour until it rises to 1180°C, and continue firing at this temperature for 0.5 hours; put 12.5kg of ignited kiln-changing materials into the kiln holes Points are put into the kiln, including 3 parts of pine branches, 1 part of raw leaves, 1 part of mahogany chips, 3 parts of coal, and 2 parts of turpentine; then continue firing at 1150 ° C for 0.8 hours, and gradually reduce the temperature in the kiln , After the green body is cooled, the fired green body is taken out, and 24 of them have undergone kiln transformation. These teapots undergoing kiln transform...

Abstract

The invention discloses a characteristic kiln change technology of Nixing ceramics, comprising the steps of preparing a blank body, molding the blank body, trimming the blank body, drying the blank body and sintering the blank body. The step of sintering the blank body comprises the following steps: 1) putting the dried blank body in a kiln, heating the temperature up to 450-550 DEG C with a heating speed of 80-120 DEG C/h, then heating the temperature up to 1100-1200 DEG C with a heating speed of 130-180 DEG C/h, and continuously sintering for 0.5-1 h at the temperature of 1100-1200 DEG C; 2) putting materials for kiln change in the kiln from a kiln hole, wherein, the additional quantity of the materials for kiln change is 2-3 kg/m<3>, and the materials for kiln change comprises 1-4 weight portions of pine, 1-3 weight portions of raw leaves, 1-3 weight portions of wood chips, 2-5 weight portions of coal and 2-4 weight portions of turpentine; 3) continuously sintering for 0.5-1 h at the temperature of 1150-1200 DEG C; 4) gradually decreasing the temperature in the kiln; and 5) after cooling, taking out the sintered blank body.

Description

technical field [0001] The invention relates to a preparation method of pottery, in particular to a characteristic kiln transformation technology of Nixing pottery. Background technique [0002] Nixing pottery refers to Qinzhou Nixing pottery. Qinzhou Nixing pottery, Jiangsu Yixing pottery, Yunnan Jianshui pottery, and Sichuan Rongchang pottery are named as my country's "Four Famous Pottery". The traditional preparation process of Nixing pottery in Qinzhou mainly includes the following steps: (1) Preparation of blank: the blank is made of pottery clay, and the soil from the east of the Qin River across the urban area of ​​Qinzhou (commonly known as Dongni: soft clay, The color is yellow-white, containing a small amount of quartz sand) and the soil in the west of the Qinjiang River (commonly known as Xini: it is a purple mudstone with high iron content, the color is purple, and there is a small amount of iron on the surface. Clay), mix the two with a certain weight ratio, an...
