Abstract
The invention discloses a production method of potteries decorated with engobe. The production method comprises following steps: 1, preparation of preform bodies; 2, preparation of engobe slurry; 3, preparation of clear glaze for further use; 4, preparation of clay bodies; 5, decoration of the clay bodies with the engobe slurry; 6, sintering; 7, glazing; and 8, sintering so as to obtain the finished products. The potteries are made of low quality materials, so that both waste utilization and low cost production are realized, and both the appearance and the quality of the finished products can reach top grade.
Description
Technical field
The present invention relates to the manufacture method of ceramic, especially relate to a kind of pottery production method that adopts engobe decorating.
Background technology
Modern ceramic, particularly ceramic ware for daily use is to becoming more meticulous and high-quality future development, and the starting material of its use require higher, more become more meticulous, cause the meticulous and high-quality raw material supply anxiety of part, and low grade or coarse starting material are dropped, and are not used.For example, the potter's clay that iron-holder is higher, when making ceramic, the whiteness of goods descends, and outward appearance is plain, and these mineral material storages are very large, and price is lower.How to adopt the potter's clay that iron-holder is higher, produce the ceramic of high-quality, the sexual development held that is related to ceramic industry, also be directly connected to the products production cost, utilize the potter's clay that iron-holder is higher to make carcass, adopt special trailing, as cosmetic soil (engobe) is decorated, improve the visual appearance of ceramic, be the problem of research of technique in ceramic industry always.
Summary of the invention
The invention provides a kind of pottery production method that adopts engobe decorating, specifically, is the method that adopts engobe decorating on the made ceramic matrix of potter's clay that iron-holder is higher adopting, and makes outward appearance and the quality of the pottery product made reach higher class.
A kind of pottery production method that adopts engobe decorating comprises the following steps:
