Problems solved by technology

[0002] Due to the decorative requirements of daily-use ceramic craft ceramics, various concave-convex lines, plates, patterns or reliefs are made on the surface. There are roughly two existing methods. One is to form concave-convex lines and curved surfaces when making ceramic blanks. Simple, lack of natural feeling, the other is the kiln deformation on the glaze surface to form bumps during the firing process, but the bumps appear randomly, which cannot be expected and controlled

Embodiment 1

[0014] Make ceramic product biscuit, be diameter 15cm, the pen container of height 20cm is totally 20.

[0015] The weight percentage: vanadium pentoxide 14%, antimony trioxide: 12%, titanium dioxide 6%, albite or potassium feldspar 12%, clay 15%, limestone 15%, quartz 10%, talc 14%, boric acid Materials with 2% sodium are mixed and ball milled, passed through a 200-mesh sieve, and water is added to make a glaze slurry with a solid content of 50%. The glaze slurry is sprayed on the biscuit to form the first glaze layer. The thickness of the first glaze layer is about 0.08mm.

[0016] Heat 900ml of water to 80°C, add 20 grams of sodium hydroxide and 10 grams of sodium vanadate, dissolve and add 100 grams of stearic acid, stir to form a paste, soak the cotton gauze in the paste and dry it. Coat paste on the green body of the glaze layer, paste cotton gauze on the green body to form 10 square grids and 10 rhombus grids, and dry.

Abstract

The invention discloses a method for forming regular convex blocks on glaze of ceramic. The method comprises the following steps: manufacturing a blank, spraying first glaze slip consisting of vanadium pentoxide, antimonous oxide, titanium dioxide, feldspar, clay, limestone, quartz, talc, sodium borate and ceramic pigment, pasting a cotton yarn mesh which is dipped in stearic acid ointment, soaking in second glaze slip consisting of feldspar, clay, limestone, quartz, talc, calcium phosphate and sodium borate, and sintering at 1250-1280 DEG C, thereby forming the regular convex blocks. Grid shaped grooves are formed in the glaze of a finished product, the convex blocks are arranged outside the grooves, the corners of the convex blocks are smooth without hand cutting feeling when being touched by hand, the depth of the grooves is generally identical to the thickness of a second glaze layer, and the effect of stereoscopic relief is achieved.

Description

technical field [0001] The invention relates to a method for manufacturing ceramic products, in particular to a method for forming regular bumps on a ceramic glaze. Background technique [0002] Due to the decorative requirements of daily-use ceramic craft ceramics, various concave-convex lines, plates, patterns or reliefs are made on the surface. There are roughly two existing methods. One is to form concave-convex lines and curved surfaces when making ceramic blanks. Simple, lacking natural feeling, the other is that the kiln deforms the glaze surface to form bumps during the firing process, but the bumps appear randomly, which cannot be expected and controlled. Contents of the invention [0003] The object of the present invention is to provide a method for making ceramic products with regular bumps formed on the ceramic glaze. [0004] The present invention comprises the following steps: [0005] A. Making green ceramic products; [0006] B. Percentage by weight: ...
