S4, preparing a sand grain basic color: mixing 90 parts of frit sand grains B and 10 parts of pigment to obtain a matched glaze A;

s5, preparing sand grain glaze: uniformly stirring 90 parts of ground glaze and 10 parts of sand grain color;

s6, coloring: uniformly painting the prepared sand glaze on the pottery clay blank for 3 to 4 times;

s7, firing: and directly calcining the painted product for 12 hours in a kiln at 1200 ℃ to obtain the sand glazed ceramic product.

2. The method for preparing a sand glazed ceramic according to claim 1, wherein the residue in the mixture is 0.08-0.12% after grinding for 12 hours in step S2.

3. The method for preparing a sand glaze ceramic according to claim 1, wherein the step of coloring in step S6 is to put the prepared sand glaze into a special vessel, stir it continuously, and paint it onto the pottery clay body 3 to 4 times uniformly with a T5 brush pen.

Technical Field

The invention relates to the field of ceramics, in particular to a preparation method of sand glaze ceramics.

Background

The traditional ceramic glaze is smooth and has single hand feeling, and the color of glaze water is changed to improve the ornamental value and the using effect mainly by using matt, semi-matt or bright glaze or processing stained paper, if necessary, some ornaments are stuck on the glaze to enhance the stereo degree, so that the working procedures and the cost are increased, the adhesive force is easy to drop, and the ceramic glaze cannot be durable.

Disclosure of Invention

The invention aims to solve the technical problems and provides a preparation method of sand grain glaze ceramics, which directly adds special sand grains into glaze water, directly grinds the sand grains into glaze slip, and manually paints the glaze slip on ceramics, so that the produced sand grain glaze ceramics has vivid effect, uniform and comfortable hand feeling, and the size and the density of the sand grains can be manually controlled to achieve ideal effect, extremely have ornamental and artistic properties, and greatly increase the grade and the additional value of the ceramics.

In order to achieve the purpose, the invention adopts the technical scheme that: a preparation method of sand glaze ceramic comprises the following steps:

s1, preparing sand grains: taking 10 parts of aluminum powder, 20 parts of kaolinite, 30 parts of potassium feldspar, 30 parts of quartz and 10 parts of calcium carbonate, and uniformly mixing; placing into a frit furnace, and placing into a kiln to calcine for 12 hours at 1200 ℃ to obtain frit;

s2, filtering: crushing the clinker calcined in the step S1, and filtering by a 120-mesh filter screen to obtain clinker sand grains B;

s3, preparing a base glaze: 30 parts of Suzhou soil, 20 parts of kaolin, 10 parts of talc, 10 parts of quartz, 20 parts of potassium feldspar and 10 parts of fluxing agent; mixing with water according to the proportion of 1: 0.6-0.8, grinding for 12 hours by a bottom grinder, and removing iron and filtering to obtain the ground glaze.

S4, preparing a sand grain basic color: mixing 90 parts of frit sand grains B and 10 parts of pigment to obtain a matched glaze A;

s5, preparing sand grain glaze: uniformly stirring 90 parts of ground glaze and 10 parts of sand grain color;

s6, coloring: putting the prepared sand glaze into a special vessel, continuously stirring, fully dipping the prepared sand glaze with a T5 brush pen, and uniformly painting the sand glaze on a pottery clay blank for 3 to 4 times;

s7, firing: and directly calcining the painted product for 12 hours in a kiln at 1200 ℃ to obtain the sand glazed ceramic product.

Compared with the prior art, the sand grain glaze ceramic prepared by the preparation method has vivid effect, uniform and comfortable hand feeling, and the size and density of the sand grains can be manually controlled to achieve ideal effect, extremely high ornamental and artistic properties, and greatly increase the grade and added value of the ceramic.
