Problems solved by technology

[0006] However, among the basic ingredients of the above-mentioned celadon glazes, only copper oxide can turn green in an oxidizing atmosphere. Not only is it difficult to control the amount of the ingredients, but a little carelessness will cause the glaze color to be yellowish or bluish; is an oxidizing atmosphere, Fe 3+ converted to Fe 2+ less likely, the effect of auxiliary color development is weak, and the glaze color is inevitably yellowish

Embodiment 1

[0032] A method for making celadon glazed porcelain, comprising the following steps:

[0033] (1) Use the following raw materials to prepare glaze slurry:

[0034] In parts by weight, the raw materials are composed of: 20 parts of agate stone, 295 parts of quartz, 85 parts of potassium feldspar, 110 parts of limestone, 8 parts of purple gold soil, 180 parts of ridge root glaze soil, 5 parts of this medicine, 9 parts of talcum powder, 24 parts of copper ore, 6 parts of bovine bone, 3 parts of copper oxide, 1 part of zinc oxide, 2 parts of cobalt oxide, 2 parts of nickel monoxide, 3 parts of composite superplasticizer and 6 parts of tin oxide. The composite water reducer is a binary composite water reducer composed of sodium pyrophosphate-naphthalene series high-efficiency water reducer and sodium pyrophosphate-sodium citrate at a mass ratio of 1:1; The high-efficiency water reducer is compounded with a mass ratio of 2:3, and the other component is compounded with sodium pyroph...

Embodiment 2

[0049] A method for making celadon glazed porcelain, comprising the following steps:

[0050] (1) Use the following raw materials to prepare glaze slurry:

[0051] In parts by weight, the raw materials are composed of: 22 parts of agate stone, 290 parts of quartz, 155 parts of potassium feldspar, 75 parts of limestone, 6 parts of purple gold soil, 130 parts of ridge root glaze soil, 7 parts of this medicine, 14 parts of talcum powder, 22 parts of copper ore, 5 parts of bovine bone, 4 parts of copper oxide, 1 part of zinc oxide, 3 parts of cobalt oxide, 3 parts of nickel monoxide, 2 parts of composite superplasticizer and 7 parts of tin oxide.

[0052] The composition of the composite water reducer is the same as in Example 1.

[0053] The preparation method of the glaze slurry is as follows: the above raw materials are crushed and mixed according to a preset ratio, and then 35% of the total amount of mixed raw materials is added to water for wet grinding; the slurry obtained ...

Embodiment 3

[0062] A method for making celadon glazed porcelain, comprising the following steps:

[0063] (1) Use the following raw materials to prepare glaze slurry:

[0064] In parts by weight, the raw materials are composed of: 28 parts of agate stone, 356 parts of quartz, 93 parts of potassium feldspar, 86 parts of limestone, 10 parts of purple gold soil, 195 parts of ridge root glaze soil, 4 parts of this medicine, 12 parts of talcum powder, 23 parts of copper ore, 4 parts of bovine bone, 4 parts of copper oxide, 1 part of zinc oxide, 1 part of cobalt oxide, 2 parts of nickel monoxide, 3 parts of composite superplasticizer and 8 parts of tin oxide.

[0065] The preparation method of the glaze slurry is as follows: the above raw materials are crushed and mixed according to a preset ratio, and then 30% of the total amount of mixed raw materials is added to water for wet grinding; the slurry obtained through wet grinding is passed through a 300-mesh sieve, and the old After 30 hours, a...

Abstract

The invention discloses a celadon glaze and a preparation method thereof. In parts by weight, the raw material formula of the celadon glaze is as follows: 15-30 parts of agate stone, 280-400 parts of quartz, 60-160 parts of potassium feldspar, and 70-120 parts of limestone. 6-10 parts of purple gold soil, 70-230 parts of lingen glaze soil, 4-8 parts of this medicine, 7-15 parts of talcum powder, 22-26 parts of copper ore, 4-7 parts of bovine bone, 2 parts of copper oxide ~4 parts, 1~2 parts of zinc oxide, 1~3 parts of cobalt oxide, 1~3 parts of nickel monoxide and 1~4 parts of composite superplasticizer. The combination of zinc oxide, cobalt oxide and nickel monoxide makes the glaze color appear blue in different degrees, and the addition of nickel monoxide can avoid the phenomenon of yellowish glaze color caused by excessive ferric iron content in the glaze; after synergistic compounding with copper oxide, the glaze color It is more stable and less likely to appear bluish or yellowish; celadon glaze is fired in an oxidizing atmosphere, and the fuel is fully burned, saving energy and reducing harmful gases.

Description

technical field [0001] The invention belongs to the technical field of celadon firing, and in particular relates to a celadon glaze and a manufacturing method thereof. Background technique [0002] The coloring mechanism of traditional Chinese celadon glazes (including Guan Kiln, Ge Kiln, Brother Kiln, Ru Kiln, and Yaozhou Kiln) is basically the same. They are all colored by iron ions in transition elements and fired with a reducing flame to make the Fe in the glaze 3+ converted to Fe 2+ . Depending on the strength of the reducing flame, the Fe in the glaze 2+ and Fe 3+ The content of celadon will also vary, so that the celadon glaze will show different shades similar to pink green, shadow green, plum green and holly. [0003] However, due to the need to control the content of oxygen and CO in the kiln during the firing process, the atmosphere in the reduction stage is difficult to control, which leads to varying degrees of deviation in the glaze color of the product, sm...
