Problems solved by technology

[0002] Coloring the surface of daily-use ceramic dishes is a common method to increase the beauty of the product. Generally, screen printing, hand-painted patterns on the glaze or direct drawing of patterns are used; water-blocking oil-adjustable glaze powder is also used to scrape patterns under the glaze. These methods cannot naturally integrate the rendering effect between the pattern and the glaze layer. The products produced are relatively dull, the glaze effect is flat, the glaze layer is not easy to grasp, it is difficult to control the quality, and it is easy to form defects such as shrinkage glaze and dirty color, which affect the quality of the product. The overall decorative effect of the product, a little further improvement

preparation example Construction

[0039] A method for preparing craft porcelain with a glazed surface having the effect of raised particles, comprising the steps of:

[0040] Step 1, weighing the raw materials of the green body according to their weight parts, crushing and sieving to obtain powder, and wet ball milling the powder to obtain mud;

[0041] Step 2, degassing, aging and drying the mud material to obtain a green body;

[0042] Step 3, placing the green body in a kiln, firing at 950-980°C for 6-8 hours to obtain a ceramic green body;

[0043] Step 4, weighing the raw materials of the glaze slurry according to their weight, crushing, sieving, and wet ball milling to obtain a glaze, and then mixing the prepared glaze and frit dry particles evenly in a certain proportion to obtain a surface glaze;

[0044] Step 5, applying glaze on the ceramic biscuit;

[0045] Step 6, sending the glazed ceramic biscuit into a kiln for sintering, so as to obtain craft porcelain with the effect of raised particles on t...
