Embodiment 1

[0016] A golden spot red glaze prepared from the following raw materials in parts by weight: 40-50 parts of leiosite, 12-18 parts of yellow feldspar, 6-10 parts of quartz, 12-16 parts of calcite, and 4-8 parts of copper ore , 2-4 parts of tin oxide, 0.8-1.2 parts of copper oxide, 3-7 parts of calcined talc, 2-4 parts of zinc oxide, and 3-7 parts of acetone.

[0017] The preparation method of above-mentioned golden spot red glaze comprises the following steps:

[0018] (1) Mix the above raw materials with water, and ball mill to obtain glaze slurry;

[0019] (2) Glazing;

[0020] (3) Firing, the firing temperature is 1280-1300°C.

[0021] The firing process in step (3) specifically includes the following steps: ①Oxidation period: put the glazed green body into the kiln, and fire it in an oxidizing atmosphere, so that the temperature rises to 1000-1060 ° C evenly in 2-3 hours; ②Under reducing atmosphere, raise the temperature uniformly to 1280-1300°C in 6-8h; ③Under reducing ...

Embodiment 2

[0024] A golden-spotted red glaze prepared from the following raw materials in parts by weight: 45 parts of leiosite, 15 parts of yellow feldspar, 8 parts of quartz, 14 parts of calcite, 6 parts of copper ore, 3 parts of tin oxide, and 1 part of copper oxide , 5 parts of calcined talc, 3 parts of zinc oxide, and 5 parts of caustic soda.

[0025] The preparation method of above-mentioned golden spot red glaze, comprises the following steps:

[0026] (1) Mix the above raw materials with water, ball mill, and pass through a 250-mesh sieve to obtain glaze slurry;

[0027] (2) Glazing;

[0028] (3) Firing, which specifically includes the following steps: ① Oxidation period: Put the glazed green body into the kiln, and fire it in an oxidizing atmosphere, so that the temperature rises to 1030°C evenly in 2.5 hours; ② Under a reducing atmosphere, Raise the temperature uniformly to 1280-1300°C within 7 hours; ③Under reducing atmosphere, keep at 1280-1300°C for 3.5h; ④Cool to room tem...

Abstract

The invention discloses golden masaic red glaze and a preparation method thereof. The disclosed golden masaic red glaze is prepared from the following raw materials in parts by weight: 40 parts to 50 parts of white feldspar, 12 parts to 18 parts of melilite, 6 parts to 10 parts of quartz, 12 parts to 16 parts of calcite, 4 parts to 8 parts of copper ores, 2 parts to 4 parts of tin oxide, 0.8 part to 1.2 parts of copper oxide, 3 parts to 7 parts of burned talc, 2 parts to 4 parts of zinc oxide, and 3 parts to 7 parts of sodium silicate. The preparation method of the golden masaic red glaze comprises the following steps: (1) adding water into the raw materials and mixing the water with the raw materials, and carrying out ball milling to obtain glaze slurry; (2) glazing; (3) firing at firing temperature of 1280 to 1300 DEG C. After tests on the golden masaic red glaze are conducted for many times, after a plurality of mineral substances are introduced and the proportions are regulated, a variety of golden masaic are appeared on the conventional red glaze, so that the conventional glaze color that the golden masaic cannot appear on the red glaze is broken through, and the problem of dull color of the red glaze on the current market is solved.

Description

technical field [0001] The invention relates to the technical field of Jun porcelain manufacture, in particular to a gold-spotted red glaze. Background technique [0002] Jun porcelain originated in the Eastern Han Dynasty. It is one of the five famous kiln porcelains in the Song Dynasty. It is a treasure in the traditional Chinese porcelain making process. Hou Town's unique national treasure porcelain. The red glaze in Jun porcelain is red and thick, moist and even, gorgeous and not vulgar. Although the red glaze will flow downward during the high-temperature firing process, the colored glaze generally does not blur. Generally, copper oxide is used as the colorant, and the red glaze is fired in a reducing atmosphere. Red glaze has the disadvantage of monotonous color, and it is difficult to make, and the treasure rate is low. Contents of the invention [0003] The invention provides a gold-spotted red glaze and a preparation method thereof to solve the problems of mono...
