preparation example A1

[0056] A base glaze slurry, the preparation method of which is as follows: weigh 8.8 kg of dry purple mud powder, 2.6 kg of ferric oxide powder, 3.2 kg of magnesium oxide powder, 2.3 kg of limestone powder, 75 kg of base glaze preparation water, and high alumina ball stone ball mill. 9kg mixed ball mill, the bottom glaze preparation water is made of water and calcium hydroxide in a mass ratio of 100:1.3, ball milled for 3 hours, and then sieved with a 200-mesh sieve to remove large particles, the sieve retention rate is less than 0.2wt%, and then add the bottom glaze to prepare water Slurry adjusted to 35 Baumé. The total amount of water used to prepare the base glaze is 9.7kg.

preparation example A2～A4

[0058] A base glaze slurry, based on the preparation example A1, the difference lies in the amount of raw materials of the base glaze slurry.

[0059] The amounts of raw materials used in Preparation Examples A1 to A4 are shown in the following table.

[0062] [Example of preparation of glaze paste]

preparation example B1

[0064] A kind of surface glaze slurry, its preparation method is as follows:

[0065] M1: Weigh 2.15kg of ferric oxide powder, 7.4kg of purple clay dry powder, 8kg of water, and 5kg of high-alumina ball stone ball mill, and mill them together for 3 hours. Then use a 200-mesh sieve to remove large particles, and the sieve retention rate is less than 0.15wt. %, and then add the bottom glaze to prepare the initial grinding slurry with water adjusted to 45 Baume degrees;

[0066] M2: The initial grinding slurry is stirred and aged for 18 hours, and then defoamed and supplemented with water to adjust the consistency to 45 Baume to obtain the glaze slurry.

[0067] The amount of active water added in steps M1 and M2 is 9.06kg.

Abstract

The present application relates to the field of ceramics, and discloses a black-ground silver-light reticulated glaze, a preparation method, and a porcelain body with a black-ground silver-light reticulated glaze. The following raw materials by mass: 88-93 parts of purple mud dry powder, 2.6-3.4 parts of ferric oxide powder, 3.2-3.7 parts of magnesium oxide powder, 2.3-2.8 parts of limestone powder; the glaze slurry includes the following raw materials by mass: tetroxide 21.5-24.6 parts of tri-iron powder, 74-77 parts of purple clay dry powder; preparation and firing includes the following stages: heating to 558-565 ℃, heating time 290-310min; continue heating to 895-908 ℃, heating time 185-210min, After the heating is completed, keep the temperature for 8~15min; continue to heat up to 1235~1260℃, the heating time is 350~365min, after the heating is completed, keep the temperature for 25~35min; cool down to 1126~1160℃, the cooling time is 140~160min; The components of the glaze are fired at a specific temperature. When the top glaze is sintered and melted, it diffuses and turns black after cooling. When the bottom glaze is sintered and melted, it converges and shrinks and bulges out to reveal the top glaze. Bottom silver pattern" glaze.

Description

technical field [0001] The present application relates to the field of ceramics, more specifically, it relates to a black-base silver-gloss reticulated glaze, a preparation method, and a porcelain body with a black-base silver-gloss reticulate glaze. Background technique [0002] Glaze is a colorless or colored vitreous thin layer covering the surface of ceramic products. It is made of mineral raw materials and raw materials in a certain proportion after grinding to make a glaze slurry, which is applied to the surface of the body and calcined at a certain temperature. The glaze not only protects the ceramics, but also has the effect of beautifying the decoration of the ceramics. Existing ceramic glaze layers include paste glaze, painted glaze or solid color glaze. Among them, the paste glaze is obtained by attaching the pre-prepared glaze flowers to the porcelain and then firing. Painted glaze is made by artificially using glaze paste to draw the imagined pattern on the gr...
