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
Some handicrafts are prone to mildew in a humid environment due to their storage place or climate problems, making their appearance ugly and affecting people's health

Abstract

The invention discloses a preparation method of a mould proof ceramic artwork. The method comprises the following steps: 1) preparing a colorant; 2) preparing a glaze, namely, weighing 10-16% of the colorant obtained in step 1), and 84-90% of lime glaze; diluting and uniformly mixing the colorant and the lime glaze; then sieving through 500 meshes to obtain the glaze; 3) soaking the biscuited ceramic artwork in a soaking solution for 1-2h; naturally drying by air; freezing in a freezing warehouse under the temperature of -10 to 20 DEG C for 8-12h; moving out; and standing under normal temperature for 12-16h; glazing; and roasting through a kiln under the temperature of 1000-1200 DEG C to obtain the ceramic artwork. The prepared artwork is bright in color, hard to mould, uniform in color, and good to human health after long-term use, and is particularly used in humid coastal regions.

Description

technical field [0001] The invention relates to ceramic handicrafts, in particular to a method for preparing mildew-proof 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. Some handicrafts are prone to mildew in a humid environment due to their storage places or climate problems, making their appearance ugly and affecting people's health. Contents of the in...
