Embodiment 1

[0049] A firing process for a black gold bowl, comprising a biscuit firing process and a glazing firing process carried out in sequence, wherein the biscuit firing process comprises the following steps:

[0050] (1) Select materials, take the plain soil and put it into a ball mill, and ball mill it into clay particles with a particle size of 200 meshes for later use;

[0051] (2) Magnetic separation, adding water to the clay particles prepared in step (1), and mixing them into a slurry, and then putting them into a magnetic separator for iron removal treatment to remove ferric oxide and tetroxide in the clay three iron;

[0052] (3) Filter mud, filter the slurry that has completed the iron removal treatment in step (2), transfer the obtained filter residue to a mud filter machine, control the pressure of the filter mud to 0.9MPa, and press for 45 minutes to obtain a mud cake for future use ;

[0053] (4) Mud refining, transfer the mud cake obtained in step (3) to a vacuum mu...

Embodiment 2

[0064] A firing process for a black gold bowl, comprising a biscuit firing process and a glazing firing process carried out in sequence, wherein the biscuit firing process comprises the following steps:

[0065] (1) Select materials, take plain soil and put it into a ball mill, and ball mill it into clay particles with a particle size of 220 mesh, and set aside;

[0066] (2) Magnetic separation, adding water to the clay particles prepared in step (1), and mixing them into a slurry, and then putting them into a magnetic separator for iron removal treatment to remove ferric oxide and tetroxide in the clay three iron;

[0067] (3) filter the mud, filter the slurry that has completed the iron removal treatment in step (2), transfer the obtained filter residue to the mud filter, control the pressure of the filter mud to 1MPa, and press for 35 minutes to obtain a mud cake for later use;

[0068] (4) Mud refining, transfer the mud cake obtained in step (3) to a vacuum mud refining m...

Embodiment 3

[0079] A firing process for a black gold bowl, comprising a biscuit firing process and a glazing firing process carried out in sequence, wherein the biscuit firing process comprises the following steps:

[0080] (1) Select materials, take plain soil and put it into a ball mill, and ball mill it into clay particles with a particle size of 180 mesh, and set aside;

[0081] (2) Magnetic separation, adding water to the clay particles prepared in step (1), and mixing them into a slurry, and then putting them into a magnetic separator for iron removal treatment to remove ferric oxide and tetroxide in the clay three iron;

[0082] (3) Filtrate the mud, filter the slurry that has completed the iron removal treatment in step (2), transfer the obtained filter residue to a mud filter machine, control the pressure of the filter mud to 0.8MPa, and press for 50 minutes to obtain a mud cake for later use ;

[0083] (4) Mud refining, transfer the mud cake obtained in step (3) to a vacuum mu...

Abstract

A firing process of a black gold bowl comprises a biscuit firing process and a glazing firing process which are sequentially carried out, and the firing process can naturally form gold edges in the glazing firing process, a finished black glaze is uniform in texture, gentle and fine, the glaze surface is transparent and smooth, the interior has a complicated and overlapped polycrystalline structure, the density and hardness are high, the heat preservation property is good, and the glaze surface of the black gold bowl is fine, smooth and bright. According to the invention, the specially-made glaze is adopted, the black gold bowl is prepared by a unique firing process, a lost traditional process is restored to the greatest extent in glaze color, the ignition loss rate is extremely low, the fineness is better, and the overall performance is more excellent.

Description

technical field [0001] The invention relates to the technical field of ceramic production, in particular to a firing process of a black gold bowl. Background technique [0002] Black glazed porcelain is a kind of traditional glazed porcelain that first appeared in the Eastern Han Dynasty. Its glaze is black and contains iron oxide and various trace element colorants. The firing process of this glaze color is superb, and the firing process reduces the main color component iron and trace elements copper, manganese, cobalt, etc. to the best effect. The finished black glazed porcelain has the characteristics of bright glaze color, transparent and uniform, and mysterious atmosphere, and is loved by porcelain lovers at home and abroad. However, due to the change of dynasties and continuous wars, the firing process of black glazed porcelain with unique color rendering effect and permeability was lost, and it was difficult to restore its effect in subsequent imitation processes, ev...
