Embodiment Construction

[0022] As a preferred embodiment of the present invention, a method for preparing a single-layer kiln-changing glaze comprises the following steps:

[0023] Ⅰ. Preparation of glaze: 10-15 parts of medium-temperature lead-free high-sodium frit, 10-15 parts of borosilicate, 15-20 parts of nepheline, 15-20 parts of quartz, 8-10 parts of calcium carbonate, 4 1 part of barium carbonate, 8-10 parts of calcined zinc oxide, 10 parts of kaolin, 5-10 parts of titanium oxide or rutile, 2-8 parts of colored oxides or lead-free ceramic pigments are mixed to make a mixture, and then proportioned by weight It is a mixture: water = 1:0.75-0.85, add water, and make glaze after ball milling. The prepared glaze is passed through a 220-mesh sieve. The above-mentioned colored oxides are one or a combination of copper carbonate, cobalt oxide, manganese oxide, and iron oxide. The above-mentioned lead-free ceramic pigments are lead-free rare earth pigments. The purity of the above-mentioned boron s...

Abstract

The invention relates to a single-layer fambe colored glaze which is directly applied to the surface of an artistic porcelain body. The glaze is composed of the following components in parts by weight: 10-15 parts of moderate-temperature lead-free high-sodium fusion cake, 10-15 parts of borosilicate, 15-20 parts of nepheline syenite, 15-20 parts of quartz, 8-10 calcium carbonate, 4 parts of barium carbonate, 8-10 parts of calcined zinc oxide, 10 parts of kaolin, 5-10 parts of titanium oxide or rutile, and 2-8 parts of coloring oxide or lead-free ceramic pigment. The invention also relates to a preparation method of the single-layer fambe colored glaze. According to the single-layer fambe colored glaze, anorthite and niter microcrystals are formed in sodium borosilicate glass by high-temperature calcination, wherein the anorthite forms bundles, and the niter forms crystal points; and the two microcrystals are mutually staggered to form the unique fambe effect. Different coloring oxides or lead-free ceramic pigments can be added to prepare the series fambe colored glazes with different colors and similar fambe effects.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a single-layer kiln color-changing glaze and a preparation method thereof. Background technique [0002] Kiln glaze has always been regarded as artistic glaze and loved by people. The so-called kiln change refers to the fact that during the firing process of porcelain, various colored oxides contained in the glaze are oxidized or reduced due to changes in the temperature in the kiln, which may show unexpected glaze effects after the porcelain comes out of the kiln. Because the kiln-changed glaze appeared by accident and has a special shape, people only know that it is obtained from the changes in the firing process in the kiln, so it is called "kiln-changed glaze". As the saying goes, "the kiln is unparalleled", which means that the kiln's glaze is unpredictable and unique. But for batches of ceramic industrial production, stable product quality is also indispensable. Therefor...
