example 1

[0024] Take the following materials and carry out proportioning according to parts by weight:

[0025] Albite 25 parts Calcite 10 parts Talc 20 parts Zinc oxide 5 parts

[0026] 20 parts of quartz, 5 parts of kaolin, 15 parts of iron red

[0027] The above-mentioned ingredients are mixed and ball milled for 48 hours (material: ball: water=1: 1.8: 0.8) and the resulting slurry after passing through a 250 mesh sieve is the glaze of the present invention, and then the glaze is applied to the green body, (the thickness of the glaze layer is 0.3 -0.5mm), after drying, it is fired in a roller kiln at a temperature of 1280°C, and the firing cycle is 8 hours. It will produce a black base color, a yellow-green crystal product, and the crystals in the glaze are evenly distributed, and the effect is very good.

example 2

[0029] Take the following materials and carry out proportioning according to parts by weight:

[0030] Albite 20 parts Calcite 18 parts Talc 15 parts Zinc oxide 3 parts

[0031] Quartz 25 parts Kaolin 3 parts Iron Red 5 parts

Embodiment 2

[0032] The manufacturing process of the second embodiment is the same as that of the first embodiment. Mix the above ingredients and ball mill for 48 hours (material: ball: water = 1: 1.8: 0.8) and pass through a 250 mesh sieve to obtain the slurry of the present invention, which is applied to the green body, (the thickness of the glaze layer is 0.3- 0.5mm), after drying, it is fired in a roller kiln at a firing temperature of 1280°C and a firing cycle of 8 hours. It will produce a black base color and a yellow-green crystal product. The crystals in the glaze are evenly distributed, and the effect is very good.

Abstract

The iron and zinc augite crystalline glaze is prepared through introducing great amount of ferric oxide and zinc oxide into augite crystalline glaze and through a conventional color glaze sintering process. Chemically, the iron and zinc augite crystalline glaze consists of SiO2 50-60 wt%, AL2O3 5-8 wt%, K2O 0-1 wt%, Na2O 2.5-3.5 wt%, CaO 6-7 wt%, MgO 5 -6 wt%, Fe2O3 5-15 wt% and ZnO 3-10 wt%. The iron and zinc augite crystalline glaze is prepared with the materials including albite 20-35 weight portions, calcite 10-18 weight portions, talcum 15-25 weight portions, iron red 5-15 weight portions, zinc oxide 3-10 weight portions, kaolin 3-5 weight portions and quartz 20- 30 weight portions.

Description

Technical field: [0001] The invention belongs to a ceramic glaze and a preparation method thereof, in particular to a glaze for daily-use ceramics and surface crystalline glazes of furnishing ceramics and a batching method thereof, and belongs to the field of preparation of ceramic glazes. For decorating surfaces in ceramics for household use and for displaying ceramics. Background technique: [0002] Crystalline glaze is a kind of artificial crystal pattern glaze, which is a glaze that introduces a crystallization agent into the basic glaze and controls the formation of various shapes and patterns in the glaze layer through firing. Most of the current crystal glaze products are display ceramic products, and the products decorated with crystal glaze have special artistic effects and are favored by the market. However, there are deficiencies in daily-use ceramic tableware decorated with crystal glaze: [0003] 1. The crystalline glaze is unstable and cannot be matched with ...
