Problems solved by technology

Most of the peers in the ceramic industry use copper oxide as the main coloring material for making red glazes, and let it be obtained in a reduction firing environment; but because the reduction firing environment is difficult to control, the coloring effect is extremely unstable, so Dahong glaze is a kind of glaze color that is extremely difficult to develop in ceramic glaze colors

Embodiment 2

[0032] A kind of medium-temperature bright red glaze, which is composed of the following raw materials: potassium feldspar 23.8%, albite 3.2%, frit 14.2%, three treasure powder 7.2%, quartz powder 18.7%, calcite 14.7%, zinc oxide 1.2% %, zirconium silicate 1.4%, kaolin 11%, talcum powder 2.8%, wollastonite 1.8%.

Embodiment 3

[0034] A medium-temperature red glaze, which is composed of the following raw materials: 27.9% potassium feldspar, 5.8% albite, 13.5% frit, 7.5% three-treasure powder, 14.2% quartz powder, 13.2% calcite, and 1 zinc oxide %, zirconium silicate 3.2%, kaolin 9.7%, talc 2.4%, wollastonite 1.6%.

[0035] The present invention also provides a preparation method for preparing the above-mentioned medium-temperature scarlet glaze, comprising the following steps:

[0036] S1, weigh raw materials according to the above ratio;

[0037] S2. Pour the raw materials weighed in step S1 into a ball mill tank for ball milling;

[0038] S3, filtering, filtering the ball-milled raw materials through an ultrafine screen, and mixing the filtered raw materials;

[0039] S4. Add water and mix thoroughly according to the component requirements.

[0040] In this embodiment, in the step S2, each raw material needs to be finely ground for 20-24 hours during the ball milling treatment.

Abstract

The invention discloses a medium-temperature bright red glaze and a preparation method thereof. The medium-temperature bright red glaze is prepared from the following raw materials in percentage by weight: 22-28% of potassium feldspar, 3-6% of albite, 10-15% of frit, 4-8% of Sanbao powder, 12-19% of quartz powder, 10-15% of calcite, 0.8-3% of zinc oxide, 1-4% of zirconium silicate, 8-12% of kaolin, 1-3% of talcum powder and 0.7-2% of wollastonite. The glaze has the beneficial effects that the glaze is smooth in hand feeling, uniform in color, durable, resistant to abrasion, good in smoothnessand thermal stability and wide in firing range, the range brightness is good when the temperature ranges from 1,195 DEG C to 1,250 DEG C, color development is bright, the standard of high-quality porcelain is met, and the glaze is suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a medium-temperature bright red glaze and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life and the change of consumption concept, daily-use ceramic products are required to be practical, artistic and ornamental. In order to improve the practicability, artistry and appreciation of daily-use porcelain, it is often necessary to adopt a variety of surface decoration methods, such as the use of bright red to express a cheerful and festive atmosphere. Most of the peers in the ceramic industry use copper oxide as the main coloring material for making red glazes, and let it be obtained in a reduction firing environment; but because the reduction firing environment is difficult to control, the coloring effect is extremely unstable, so Dahong glaze is a kind of glaze color that is extremely difficult to develop among ceramic glaze...
