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, lacking 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, so ceramic products with the appearance effect of simulating snake skin scales cannot be formed

Embodiment 1

[0016] Make ceramic product biscuit, be diameter 15cm, the pen container of height 20cm is totally 20.

[0017] The weight percentage: tin dioxide 3%, zirconium dioxide 8%, nickel oxide 2.5%, cobalt oxide 1.5%, vanadium pentoxide 8%, antimony trioxide 6%, albite feldspar 15%, clay 10%, 15% limestone, 15% quartz, and 16% talc are ball milled, passed through a 200-mesh sieve, added water to make a glaze slurry with a solid content of 45%, and spray the glaze slurry on the biscuit to become the first glaze layer. The thickness is about 0.08mm.

[0018] Heat 900ml of water to 80°C, add 20g of sodium hydroxide, 10g of sodium vanadate, dissolve and add 100g of stearic acid, stir to form a paste, soak the paste with cotton gauze and dry it, apply the Paste is applied to the biscuit of the first glaze layer, and the cotton gauze is pasted on the biscuit to form a square grid and dried.

[0019] The percentage by weight: albite 12%, clay 20%, limestone 15%, quartz 10%, talc 20%, calc...

Abstract

The invention discloses a ceramic product having a snakeskin-scale appearance effect. The method comprises the following steps of preparing a biscuit, spraying a first glaze layer comprising tin oxide, zirconium oxide, nickel oxide, cobalt oxide, vanadium pentoxide, antimony trioxide, feldspar, clay, limestone, quartz and talc, adhering cotton gauze soaked with stearic acid pasty fluid, spraying a second glaze layer comprising feldspar, clay, limestone, quartz, talc, calcium phosphate, nickel oxide, cobalt oxide, spraying a third glaze layer comprising tin dioxide, zirconium dioxide, nickel oxide, cobalt oxide, iron oxide, manganese dioxide, diboron trioxide, sodaclase, clay, limestone, quartz, talc and calcining at 1200-1250 DEG C to obtain the finished product.

Description

technical field [0001] The invention relates to a method for manufacturing ceramic products, in particular to a method for forming the appearance effect of snakeskin scales 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 on the glaze surface to form bumps during the firing process, but the bumps appear randomly, which cannot be expected and controlled, so ceramic products with the appearance effect of simulating snake skin scales cannot be formed. Contents of the invention [0003] The object of the present invention is to provide a ceramic product with the appearance effect of snake skin scales. [0004] The present invention co...
