Problems solved by technology

Firewood firing is the oldest firing technology for ceramics and purple pottery. However, due to the difficulty in temperature control, high firing cost, and difficult control of product quality, a large number of manufacturers now use it. Low gas furnace firing, electric furnace firing technology
However, it is precisely because of the uncertainty of the firing process and results of firewood that the finished products obtained by the natural color changes during the firing process are all works that cannot be copied. The colors are ever-changing, and there are no identical works, which are unique , making modern potters even more obsessed with firewood
The traditional Jianshui pottery clay formula includes white clay, blue clay, loess, red clay, and purple clay, also known as five-color clay. The refined clay mainly includes red clay and white clay, and red clay is composed of white clay, blue clay, loess, and red clay. , mixed with purple clay and then refined. White clay is made by mixing white clay and green clay. The firing temperature of white clay is relatively high and suitable for firewood firing conditions; It is difficult to form a good ash glaze effect during firing. However, because red clay has a high iron content, and iron is an important colorant in glaze, if the firing temperature of red clay can be raised, it will be different from white clay. Special effect

Embodiment 1

[0021] A method for preparing purple pottery products with Jianshui purple pottery wood burning mud, the steps are as follows:

[0022] (1) Preparation of red mud mud for Jianshui purple pottery firewood burning:

[0023] 1) Mixing of mud materials: weigh 10% of white clay, 30% of green clay, 20% of loess, and 40% of red clay according to the weight percentage, and add it to a ball mill for ball milling;

[0024] 2) Mud screening system: After ball milling, put the mud into the mud pool, and then transport it to the vibrating screen for filtration, and the filter screen size is 200-300 mesh;

[0025] 3) Mud pressing: the filtered mud is pumped into the filter press for dehydration and pressed into mud cake;

[0026] 4) Mud refining: put the filtered and dehydrated mud cake into the vacuum mud refining machine for refining, repeat 2 to 3 times, and the mud is refined immediately;

[0027] (2) Prepare the green body of the purple pottery product by artificially drawing or pres...

Embodiment 2

[0030] The method for preparing purple pottery products with Jianshui purple pottery firewood and burning mud material, weighing 10% of white clay, 32% of green clay, 18% of loess, and 40% of red clay according to weight percentage, and refined according to the method of Example 1 to obtain red clay mud. Then prepare the green body of purple pottery product with the red mud mud material prepared by refining; The green body of purple pottery product prepared at last is put into smokeless firewood together with the white mud body prepared with Jianshui purple pottery white mud in addition Co-firing in the kiln adopts the bare-firing method of modern wood firing, and uses pine wood for firing. After firing at a temperature of 1190°C to 1210°C, the firing ends, allowing the green body to form a natural ash glaze. The fired products can be discharged from the kiln after cooling in the kiln.

Embodiment 3

[0032] The method for preparing purple pottery products with Jianshui purple pottery firewood and burning mud material, weighing 8% of white clay, 30% of green clay, 22% of loess, and 40% of red clay according to weight percentage, and refined according to the method of Example 1 to obtain red clay mud. Then prepare the green body of purple pottery product with the red mud mud material prepared by refining; The green body of purple pottery product prepared at last is put into smokeless firewood together with the white mud body prepared with Jianshui purple pottery white mud in addition Co-firing in the kiln adopts the bare-firing method of modern wood firing, and uses pine wood for firing. After firing at a temperature of 1190°C to 1210°C, the firing ends, allowing the green body to form a natural ash glaze. The fired products can be discharged from the kiln after cooling in the kiln.

Abstract

The invention discloses Jianshui (Country of Yunnan) purple pottery wood-fired pug and a product firing method thereof. The wood-fired pug is red mud pug prepared by adding water into 8 to 12 percent of argil, 28 to 32 percent of blue earth, 18 to 22 percent of loess and 38 to 42 percent of red soil. The product firing method comprises the following steps: manufacturing a purple pottery product blank from the red mud pug, then putting the blank into a smokeless wood-fired kiln, and firing pines by adopting a wood firing method, or firing the blank together with a Jianshui purple pottery argil blank, ending firing till the temperature is 1,190 to 1,210 DEG C, and cooling in the kiln to obtain a product. The firing temperature of the conventional red mud is changed via preparation of a new red mud formula, so that the difficulty in firing of Jianshui purple pottery is solved, a Jianshui purple pottery wood-fired product with rich kiln changes is obtained, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of Jianshui purple pottery clay and a firing method thereof. Background technique [0002] Jianshui purple pottery products mainly reflect two main purposes in production and life, one is as a work of art for viewing and collection; the other is used as living utensils, such as tea sets and tableware. Wood burning is the oldest firing technology for ceramics and purple pottery. However, due to the difficult temperature control, high firing cost, and difficult product quality control, a large number of manufacturers now use firing temperature and product quality that are easy to control and have a relatively high rejection rate. Lower gas furnace firing, electric furnace firing technology. However, it is precisely because of the uncertainty of the burning process and the results of wood burning that the finished products obtained from natural changes in color during the burning process are all works that can...
