Problems solved by technology

[0003] Traditional ceramic handicrafts generally use more traditional colors such as blue, bright red, etc. Handicrafts are usually products processed by hand or machine from raw materials or semi-finished products. The existing preparation methods of ceramic handicrafts are too complicated and the surface gloss Insufficient, uneven color, not bright color, easy to break under sudden cold and hot conditions, affecting the appreciation value of porcelain

Abstract

The invention discloses a preparation method of ceramic artware. The method comprises the following steps that colorant preparation is performed; 2, glaze preparation is performed: 10 to 16 percent ofcolorants and 84 to 90 percent of lime glaze obtained in the first step are weighed; the colorants and the colorants are diluted and are uniformly mixed to pass through a 500-mesh sieve; glaze is obtained; 3, the ceramic artware subjected to biscuit firing is soaked for 1 to 2h in soaking liquid; after natural air drying, the soaked ceramic artware is put into a refrigeration house being -10 to -20 DEG C to be frozen for 8 to 12h; after being taken out, the ceramic artware is placed at room temperature for 12 to 16h; then, glazing is performed; the glazed ceramic artware enters a kiln; calcination is performed at the temperature of 1000 to 1200 DEG C; the ceramic artwork is obtained; the soaking liquid is a medical stone water solution; the prepared artware has bright color and uniform color luster; after being used for a long time, the ceramic artware is beneficial for the human body.

Description

technical field [0001] The invention relates to ceramic handicrafts, in particular to a method for preparing ceramic handicrafts. Background technique [0002] Green glaze, also known as malachite green glaze, is red in a reducing atmosphere and green in an oxidizing atmosphere, and is widely used in the field of ceramics. [0003] Traditional ceramic handicrafts generally use more traditional colors such as blue, bright red, etc. Handicrafts are usually products processed by hand or machine from raw materials or semi-finished products. The existing preparation methods of ceramic handicrafts are too complicated and the surface gloss Insufficient, uneven color, not bright color, easy to break under sudden cold and hot conditions, affecting the appreciation value of porcelain. Contents of the invention [0004] In order to solve the above problems, the present invention provides a method for preparing ceramic handicrafts. The prepared handicrafts are bright in color and uni...
