Embodiment 1

[0032]Example 1: On the fine blank of the 480mm bone china vase, draw the outline of the dragon and the phoenix with a brush dipped in peelable glue, and then apply a layer of golden-yellow glaze on the outer surface of the fine blank of the 480 mm bone china vase. , The golden yellow color glaze is prepared according to the following formula: 25 parts of quartz powder (325 mesh), potassium feldspar powder (325 mesh): 25 parts, 10 parts of kaolin, 12 parts of borax, 5 parts of zinc oxide, 1 part of zirconium silicate, carbonic acid 11 parts of calcium, 5 parts of phosphorus pentoxide, 1 part of strontium carbonate, and 5 parts of lithium carbonate. After the above-mentioned raw materials are mixed uniformly, they are melted at 1400°C to 1450°C, and then quenched in cold water to form a frit. Put the frit into the ball mill, add water, high alumina ball stone and 6% kaolin to grind into glaze slurry, the fineness is controlled to be less than 0.03% of the 10,000-hole sieve, and...

Embodiment 2

[0035] Embodiment 2: on the 400mm hard porcelain flat disc fine blank, use a writing brush to dip the paraffin and draw the outline of the peony flower, and then on the outer surface of the 400mm hard porcelain flat disc fine blank, a layer of bright red color glaze, The bright red color glaze is prepared according to the following formula: 44 parts of quartz powder (325 mesh), nepheline powder (325 mesh): 20 parts, 6 parts of kaolin, 8 parts of borax, 6 parts of zinc oxide, 1 part of yttrium trioxide, calcium carbonate 9 parts, 2 parts of magnesium carbonate, 2 parts of strontium carbonate, 2 parts of lithium carbonate. After the above-mentioned raw materials are mixed uniformly, they are melted at 1450° C. and then quenched in cold water to form a frit. Put the frit into the ball mill, add water, high alumina balls and 10% kaolin to grind into glaze slurry, the fineness is controlled to be less than 0.03% of the 10,000-hole sieve, then dried at 80 ℃, and made into powder and...

Abstract

The invention discloses an enamel glaze which belongs to the technical field of ceramic materials, and the enamel glaze comprises a colored glaze basic glaze, an enamel glaze basic glaze and coloring pigments. The invention further discloses a preparation process of the enamel glaze and an application of the enamel glaze. The preparation process can improve the firing temperature of the enamel colored glaze, expand the firing range of the glaze, improve the viscosity of the enamel colored glaze and ensure that coloring metal oxides can not be diffused or the color can not be dimmed due to the flowing of the glaze by optimizing the formula of the enamel colored glaze, adopting an appropriate amount of zinc oxide for replacing heavy metal flux materials, such as lead oxide and the like, integrating the applicable color development performances of a variety of coloring materials and introducing a rare earth compound of yttrium oxide. The preparation process can further ensure that the coloring metal oxides in the enamel glaze can not be oxidized by oxygen or water vapor in the air through the way of underglaze color, thereby further ensuring that a product can not change the color or fade forever, closing heavy metals contained in the coloring oxides for avoiding solventing-out and solving the problem of heavy metal pollution.

Description

technical field [0001] The invention belongs to the technical field of ceramics, in particular to an enamel ceramic glaze and a preparation process thereof. Background technique [0002] With a long history, the enamel colored porcelain known as the "Queen of Color Porcelain" and "the official kiln in the official kiln" evolved from cloisonne, which is made of enamel glaze on a copper body, and enamel colored porcelain is in The enamel glaze is placed on the porcelain body and then fired, so the enamel colored porcelain is also called "the porcelain body painted enamel". The traditional low-temperature on-glaze color technique of painting enamel glaze on the porcelain body is used. Because the decorative pattern protrudes from the glaze surface by about 1mm, it is easy to fall off and change color after long-term friction. The glass base glaze with a large expansion coefficient contains quartz, and the melting temperature of quartz itself is high, as high as more than 1,700...
