Abstract

The invention relates to a preparation technology of white ceramic artwork. The preparation technology of the white ceramic artwork includes the following steps that S1, a clay process is carried out, wherein impurities in a clay manufacturing raw material are removed, even mixing is carried out to obtain clay, and the clay is divided and piled into columnar piled clay; S2, a blank pulling process is carried out, wherein the piled clay obtained in the step S1 is placed into a large rotary disc, the rotary disc is rotated, and the ceramic clay is pulled into a ceramic blank with the hands and a blank pulling tool; S3, a copper plate process is carried out, wherein a white film and a white copper plate are manufactured according to drawing design; S4, a discharge print process is carried out, wherein blank discharge print powder is added into discharge print raw stock, even mixing is carried out to obtain blank discharge print pigment, and discharge print coloring is carried out a printing zone according to drawing design; S5, a biscuiting process is carried out, wherein a green blank is subject to biscuiting for 3 h to 5 h; and S6, a glaze firing process is carried out, wherein a blank obtained in the S5 biscuiting process is glazed, and then glaze firing is carried out for 1 h to 1.5 h. The white ceramic artwork has the beneficial effects of being pure in color and luster, high in mechanical strength and good shock resistance.

Description

Technical field [0001] The invention relates to the technical field of ceramics, in particular to a preparation process of white ceramic handicrafts. Background technique [0002] Ceramics is the general term for pottery and porcelain. The Chinese invented pottery as early as about 8000-2000 BC (Neolithic Age). Ceramic materials are mostly oxides, nitrides, borides and carbides. Common ceramic materials include clay, alumina, and kaolin. The main raw material for it is silicate minerals derived from nature, so it belongs to the category of "silicate industry" with industries such as glass, cement, enamel, and refractory materials. Ceramic materials generally have higher hardness but poor plasticity. In addition to the use of food utensils and decorations, it also plays an important role in the development of science and technology. The ceramic raw materials are made by quenching a large amount of earth's original resource clay. The nature of clay is tough. It can be plastic...
