AI Technical Summary

Problems solved by technology

However, the technical requirements for inlay molding are relatively high. If you are not careful, the pot body cannot be rounded, and the surface of the pot is not smooth enough, and the surface cannot form cracks, so the mechanism effect is relatively monotonous, the visual effect is poor, and the shape is not good. beautiful

Embodiment 1

[0013] Raw material source is convenient among the present invention, and it mainly produces in Dingshu town, Yixing, Jiangsu, my country, and this potter's clay adopts sandy soil as main, and clay is secondary, and the kneading mud that adds water and forms can directly be bought on the market. The repurchased kneading mud is kneaded repeatedly by hand to improve the flexibility of the kneading mud. Then put the kneading mud at the center of the electric wheel of the special equipment, use both hands to pull the kneading mud into a hollow straight body, and then stay on the surface of the straight shape for 2-10 minutes, then pull it Blank expanded to the required shape of various pot blanks. The function of liquid sodium silicate is to quickly dry the surface of the hollow straight cylindrical body, and make the body wet inside and dry outside. The concentration of the liquid sodium silicate is 40-90% (percentage by weight). If the concentration of liquid sodium silicate i...

Embodiment 2

[0015] The concentration of liquid sodium silicate adopts 80% (percentage by weight) in this implementation. After the green body of the pot is coated with liquid sodium silicate, the surface of the green body is dried for 15 minutes, and the sintering temperature is 115°C. The purple sand teapot with cracks on the surface of the teapot body can be made by adopting the manufacturing process in the first embodiment.

Abstract

The invention provides a manufacturing process of a dark-red enameled pottery, and belongs to the technical field of ceramic manufacturing crafts. The manufacturing process of the dark-red enameled pottery is characterized in that kneading mud is adopted, the mud is repeatedly kneaded with hands and drawn into an inner empty straight cylinder body, the surface of the body is coated with sodium silicate to enable the body to quickly dry, then the body is expanded and drawn to a pot body shape, a spout and a handle are install for a whole pot, then drying is carried out, and finally the whole pot is put in a kiln to be sintered into a finished product. The manufacturing process of the dark-red enameled pottery has simple manufacturing process, low manufacturing cost and convenient sources ofraw materials; and for the use of a hand-drawn body forming mode, the pot body surface is coated with the easy-to-dry sodium silicate, cracks can be formed on the surface of the pot body, the aesthetic taste is enhanced and visual effect is improved, the texture beauty of purple clay can further be reflected, and appearance is elegant.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a manufacturing process of a purple clay teapot. Background technique [0002] At present, the raw material for making purple clay teapots is produced in Yixing, Jiangsu, my country. It is a very special kind of clay, which is mainly sandy soil with very little clay content. The purple sand utensils made of this kind of sand clay have good air permeability and are suitable for cold and hot performance. In the prior art, the purple clay teapot is made of this kind of sand clay, which is mixed with water and made into kneading mud, and then kneaded repeatedly by hand. Usually, it is made into various shapes by using the clay sheet inlay molding process or the stretching process. Zisha teapots are finished products after entering the kiln and sintering. This clay flake inlay molding process is a traditional and old-fashioned process, but it can also make the sand utensils made colorful. H...
