Jianshui (Country of Yunnan) purple pottery wood-fired pug and product firing method thereof

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 its firing method. Background technique [0002] Jianshui purple pottery products have two main uses in production and life. One is as a work of art for appreciation and collection; the other is as a living utensil, such as tea sets and tableware. 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...

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
