Preparation method of black pottery artware

Abstract

The purpose of the invention is to provide a preparation method of a black pottery artware. First, blank material yellow clay is selected, and processes of crushing, deposition, mud extruding, and fermentation are carried out on the yellow clay to obtain black pottery mud. Then, moulding processing is carried out on the black pottery raw material, and after the processes of shade drying, shape modification, polishing, painting, engraving, polishing once again and shade drying are carried out on an unburned earthenware body, surface treatment is carried out on the unburned earthenware body. Finally, the unburned earthenware body is put into a kiln special for black pottery sintering to carry out sintering, and the sintering process comprises preheating, heating, cooling, smoke drawing, kiln closing, and kiln moistening. In sintering, both the surface and the interior of the unburned earthenware body of the black pottery artware sintered in the invention can be carbonized uniformly, and present a black color. Fine channels favor the penetration of soot, so that the black pottery artware is pitch black and bright from inside to outside, has a natural, smooth, and non-fading color, and has no peculiar smell of asphalt or impurities. In addition, the preparation method of the invention has short sintering time, and saves both energy and labor.

Description

technical field [0001] The invention belongs to the technical field of black pottery technology, and in particular relates to a preparation method of black pottery technology. Background technique [0002] At present, the mud of clay handicrafts on the market is mostly silt, and the texture is relatively soft after firing. It is afraid of water, and the black color will fade within two or three years. After carving and firing, it will lose its gloss. The reason is that many manufacturers lack the mud refining process, and directly process the imported clay by ball milling and vacuum drying, resulting in the above shortcomings in the product. [0003] Patent No. 2004100504870 relates to a black pottery handicraft and its preparation method. It uses shale soil and low-temperature clay from Changbai Mountains as the main raw materials, and uses the shale soil and low-temperature clay from Changbai Mountains to evenly mix them. After ball milling, aging, mud refining, casting, a...

Problems solved by technology

There are certain defects in this method, that is, the asphalt is in a liquid state when firing, and the odor of the asphalt and the soluble substances when the asphalt is liquefied are not easy to remove, which affects the quality of black pottery, the firing temperature is not enough, and it breaks after soaking in water
