Embodiment 1

[0023] 1. Manufacture green body: Mix the following raw materials in parts by weight: 65 parts of laterite, 5 parts of feldspar, 5 parts of black limestone, 5 parts of fluorite, 5 parts of kaolin, 5 parts of quartz, 3 parts of lead-free frit, 2 parts of talc and 20 parts of water are mixed evenly and ground into a soil slurry. The soil slurry is injected into the mold for 0.5 hours and then demoulded, then air-dried at room temperature, and then dried naturally after trimming and wiping to obtain a green body;

[0024] 2. Manufacturing mud glaze: Mix the following raw materials in parts by weight: 85 parts of red clay, 5 parts of kaolin, 3 parts of natural river sand, 5 parts of frit, 6 parts of dry ice, and 5 parts of orange-red coloring material, and grind in a ball mill After 12 hours to form a soil slurry, take it out and filter, add 80 parts of water to the filtrate and stir, let it settle naturally for 48 hours, and remove the sediment to obtain the mud glaze;

Embodiment 2

[0028] 1. Manufacture green body: Mix the following raw materials in parts by weight: 60 parts of laterite, 6 parts of feldspar, 6 parts of black limestone, 6 parts of fluorite, 6 parts of kaolin, 6 parts of quartz, 4 parts of lead-free frit, 2.5 parts of talc and 25 parts of water are mixed and ground into a soil slurry. The soil slurry is injected into the mold for 0.75 hours, demolded and formed, air-dried naturally at room temperature, and then dried naturally after trimming and wiping to obtain a green body;

[0029] 2. Manufacturing mud glaze: Mix the following raw materials in parts by weight: 80 parts of red clay, 3 parts of kaolin, 1 part of natural river sand, 2 parts of lead-free frit, 4 parts of dry ice, and 3 parts of blue coloring material, and put them into the ball mill Grind in the ground for 10 hours to form a soil slurry, take it out and filter, add 60 parts of water to the filtrate and stir, let it settle naturally for 24 hours, and remove the sediment to ob...

Embodiment 3

[0034] 1. Manufacture green body: Mix the following raw materials in parts by weight: 63 parts of laterite, 8 parts of feldspar, 8 parts of black limestone, 8 parts of fluorite, 8 parts of kaolin, 8 parts of quartz, 4 parts of lead-free frit, 3 parts of talc and 30 parts of water are mixed and ground into a soil slurry. The soil slurry is injected into the mold for 0.8 hours and then demoulded to form. It is naturally air-dried at room temperature, and then naturally air-dried after trimming and wiping water to obtain a green body;

Abstract

The invention discloses clay glaze which consists of the following raw materials in parts by weight: 80-85 parts of red soil, 3-5 parts of kaolin, 1-3 parts of natural river sand, 2-5 parts of frit, 4-6 parts of cooling agent and 3-5 parts of coloring material. The clay glaze is natural, environment-friendly, non-toxic and beautiful, and the resources are abundant; with a unique formula, the clay glaze is firmly bonded with a blank, so that a breakthrough in joint decoration of the coloring material and clay glaze is realized, and a decoration effect on a red soil pottery product is greatly improved. The invention also discloses a production method of a red soil pottery product by use of the clay glaze, which comprises production of a red soil pottery blank, production of clay glaze, clay glaze application and sintering. After the blank is treated with the clay glaze and naturally dried, various patterns can be directly painted on the surface layer of the clay glaze as necessary; the phenomena such as clay glaze jump, bubbling, shelling and the like in sintering are avoided; after sintering, the surface layer of the clay glaze paint is smooth and has good hand feeling, so that the grade and market share of the product are greatly improved.

Description

technical field [0001] The invention relates to the technical field of ceramic technology, in particular to a mud glaze and a method for manufacturing a red soil pottery product thereof. Background technique [0002] The main raw material of red soil pottery products - laterite is rich in resources, the green body has good plasticity and is easy to shape, and the firing temperature range is wide. In the ceramic production technology, the decoration technology under red soil pottery can be generally divided into two methods: one is to add color to the unglazed adobe after trimming and wiping, and then apply a layer of transparent glaze on the surface. This method is relatively simple to operate and easy to control, and can be used for more delicate devices, but the glaze layer on the surface can only use transparent glaze to show the decorative effect of painting. However, with the improvement of living standards, the monotonous transparent glaze color has disappeared. I...
