Problems solved by technology

[0004] Due to the excessive pursuit of fine and pure raw materials in the existing technology, the cost is very high, and the process technology steps are numerous. Many kaolin with low purity are discarded at will, which also brings great pollution and damage to the environment, and also causes great damage to kaolin resources. It is wasteful, and it is unique and lacks characteristics. The output of similar products is seriously over-produced, and the differentiated characteristic products are phoenix horns, which seriously affects the development and effective promotion of ceramic culture.

Embodiment 1

[0043] A. Kaolin treatment

[0044] Put the kaolin collected from Guanlong Mountain in Shenzhen into a drying furnace, spread it evenly, raise the temperature to 120°C and dry it for 5 hours. After natural cooling, put the dried raw materials into a pulverizer and grind until the largest particle does not exceed 1 mm.

[0045] Place the pulverized kaolin at a height of 1 meter, set up a high-power fan (1.5 meters away from the raw material table), and adjust the wind power of the fan to 8-10 m / s, then put the pulverized kaolin at a speed of 60 kg / min. The rate is uniform and downward, forming a 2.0-2.5 meter long raw material pile on the ground; along the direction of the strong wind, the kaolin between 0-1m of the raw material pile is used as A 0-1 Raw material, kaolin between 1-2m of raw material pile as B 1-2 raw material.

[0046] Will B 1-2 Raw materials are placed in the first-level pool of the three-level water flow scouring pool, washed with a water flow of 1.0-1.5m...

Embodiment 2

[0065] A. Kaolin treatment

[0066] Put the kaolin collected from Guanlong Mountain in Shenzhen into a drying furnace, spread it evenly, raise the temperature to 120°C and dry it for 5 hours. After natural cooling, put the dried raw materials into a pulverizer and grind until the largest particle does not exceed 1 mm.

[0067] Place the pulverized kaolin at a height of 1 meter, set up a high-power fan (1.5 meters away from the raw material table), and adjust the wind power of the fan to 8-10 m / s, then put the pulverized kaolin at a speed of 60 kg / min. The rate is uniform and downward, forming a 2.0-2.5 meter long raw material pile on the ground; along the direction of the strong wind, the kaolin between 0-1m of the raw material pile is used as A 0-1 Raw material, kaolin between 1-2m of raw material pile as B 1-2 raw material.

[0068] Will B 1-2 The raw materials are placed in the first pool of the three-level water flow scouring pool, washed with a water flow of 1.3m / s, an...

Embodiment 3

[0088] The difference between this embodiment and Example 2 is that the proportioning composition of the preparation of the tire soil and the preparation of the glaze is different, and the proportioning composition of the tire soil of the present embodiment is: by weight, T 1 50 parts of fetal soil raw materials, T 2 35 parts of fetal soil raw materials, 3 parts of marble raw materials, 4 parts of diorite raw materials, 8 parts of white mulberry mud; the proportioning composition of solid powder in the glaze is: by weight percentage, Y 1 Glaze raw material 18%, Y 2 Glaze raw material 32%, marble 22%, diorite 22%, gum arabic 6%; Other technological conditions, method are identical with embodiment 2.

[0089] The celadon fired in this embodiment has the characteristics of relatively thick porcelain, uneven color, and a little dark gray spots.

Abstract

The invention discloses celadon and a preparation method thereof and belongs to the field of manufacturing of porcelain. The preparation method of the celadon comprises the following steps: processing kaolin, processing marble and diorite, preparing green body soil, preparing glaze, moulding and biscuiting a green body, applying glaze on the green body, and firing, wherein the kaolin is processed by the following steps: drying kaolin, spreading and blowing with strong breeze, distributing materials, scouring with water flow, precipitating, reclaiming layer by layer, screening out a kaolin raw material used for preparing the green body soil and the glaze, then firing by combining unique firing atmosphere and a warming curve to obtain the celadon which is steadier and more implicit in colour and lustre and semi-transparent in glazing colour and is provided with a grey or dark brown green body. The preparation method of the celadon is not fettered by a historic skill, body and glaze can be fine and smooth and also can be rough, glaze light is milder, the glazing colour is not pure, but differential regional characteristic is formed.

Description

technical field [0001] The invention belongs to the field of porcelain manufacture, and in particular relates to celadon and a preparation method thereof. Background technique [0002] Existing celadon varieties are few and relatively simple, basically represented by Longquan celadon, with delicate glaze, strong glaze, and pure glaze color; there are mainly two types: Ge kiln and younger kiln, which basically continue the style characteristics since the Song Dynasty and lack modern breath. [0003] Most of the celadon on the market today is Longquan celadon. In today's Longquan County, Zhejiang Province, there are many kiln sites such as Dayao, Jincun, Xikou, and Songxi. The glaze color of Longquan is generally thicker, no matter what kind of color it is, the glaze color is relatively pure, and the change of layers is not obvious, and porcelain stones containing silicon and iron are mostly used as raw materials. Flint red is found on the bottom and feet of almost every ute...
