Artistic pottery fancy glaze and manufacturing method thereof

Abstract

An artistic pottery fancy glaze mainly comprises 65 parts of sodium potassium feldspar, 3 parts of kaolin, 7 parts of lithium carbonate, 4 parts of bone ash, 4 parts of calcium carbonate, 11 parts of borax, 1 part of barium and 5 parts of quartz. Compared with the prior art, the method provided by the invention changes a formula of the glaze to reach changed fancy glaze effect, reduce expansion factor of the formula of the glaze, prevent glaze crack at low temperature and prolong utilization rate of the product; meanwhile, ceramic with the glaze has higher strength, brilliant glaze and good glossiness, compared with common ceramic.

Description

technical field

[0001] The invention relates to the technical field of ceramic glazes, in particular to an art pottery glaze and a manufacturing method thereof. Background technique

[0002] Ceramic products often need to use glaze in the production process at present, and the pottery product that existing glaze is made, its surface glossiness is poor, and color is not bright-coloured and can not form the shortcoming of various color change; On the other hand, existing If high-temperature glazed pottery kiln-transformed products are put into cold water at room temperature, the glaze on the surface of the pottery will be severely cracked, resulting in extremely poor thermal stability of the product. Contents of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a kiln-changing glaze, a variety of art pottery glazes, which can improve the glaze effect of not bright colors, single tone and anti-cracking. [0...

Examples

Embodiment Construction

[0019] A method for making artistic pottery flower glaze, comprising the following steps:

[0020] ⑴, measured by mass percentage, put 65 parts of potassium albite feldspar, 3 parts of kaolin, 7 parts of lithium carbonate, 4 parts of bone ash, 4 parts of calcium carbonate, 11 parts of borax, 1 part of barium and 5 parts of quartz at 1200 ℃ The frit is first made in the furnace;

[0021] (2) Ball mill the frit for 72 hours to make the fineness reach 250 mesh, add 2 parts of low-temperature clay, 5 parts of zinc oxide and 8 parts of coloring agent, and then continue ball milling for 12 hours;

[0022] (3) After the ball milling, in order to prevent the fluidity and precipitation of the glaze slurry, add 1 part of hydrogel in the glaze slurry;

[0023] ⑷. Fill them into containers respectively, let them stand still, and the finished art ceramic glaze is finished.

[0024] The above ceramic glazes contain chemical components such as SiO2, Al2O3, LiO2, Na2O, K2O, Fe2O3, P2O5, B2O...
