Will Nixi black pottery fade after charcoal burning?

Hello, it will not fade, the production of black pottery is mainly completed in three steps, namely: material selection, processing, and sintering. The selection of black pottery is the main link to ensure the quality, the processing depends on the artistic accomplishment of the maker, and the use of a unique sintering process to make the pottery black is the biggest feature of black pottery.

The materials of black pottery mainly contain: silicon oxide, alumina, iron oxide, titanium oxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, manganese oxide and other elements. The larger proportion is silicon oxide and alumina, which account for the sum respectively.

2] Judging from the many unearthed black pottery, most of the black pottery raw materials belong to the pure and delicate red clay impacted by the Yellow River, and because of the good plasticity of this material, it has been used to this day. Red clay is mainly distributed in the Yellow River Basin, and the middle and lower reaches are relatively delicate. Good pottery materials should go through several processes such as cooling, freezing, washing, and deposition.

The first condition is: there is enough sunlight, the ground is higher than the surroundings, and it is necessary to reflect on the sun frequently, and it is best to freeze the old mud for more than 5 years. The red clay that has been frozen by the wind is not easy to crack and is easy to use.

Most potters have such materials that are well preserved. When processing materials, be sure to note that all the slurry water must pass through the strainer! First of all, pour the air-frozen red clay into the mixing tank, then add water for careful stirring, and constantly observe the density of the mud while stirring; If it is too large to pass through the strainer, it is necessary to add more water to dilute the slurry.

The slurry through the strainer flows into the sedimentation tank, so that the entire material washing process is completed until the sedimentation tank is full. Finally, cover with a screen window to prevent dust from entering.

The above is just a personal opinion, hopefully, thank you.

Nixi black pottery is a pottery billet with high water permeability, that is, the body is porous, similar to the feeling of frozen tofu,,, after 600-800 firewood for an hour, and then attached to the straw will smolder, forcing the carbon element of the soot into the pores of the body, thus making the pottery black and colored... Carbon enters the body, the chemical elements are stable, it will not fade, and for the smoky smell, you only need to expose it to the sun for a few days, and then use it more to force the oil smoke out.

Around 800-1000 degrees.

The production of black pottery is mainly completed in three steps, namely: material selection, processing, and sintering. The selection of black pottery is the main link to ensure the quality, most of them are made of laterite, sand and weathered stone and other materials as raw materials, mixed according to the proportion, handmade into the initial adobe, the processing depends on the artistic accomplishment of the maker, followed by pattern carving, placement of handles or decorative accessories, after the production of adobe, it must be dried for about three days before it can be fired.

The use of a unique sintering process to make the pottery black is the biggest feature of black pottery. Sun Nuoqilin said: the firing temperature of black pottery is about 1000 degrees, there are three kinds of fine mud, mud and sand, among which the production level of fine mud thin-walled black pottery is the highest, and it has the reputation of "black as lacquer, thin as paper".

Hope it helps.
