The formula and preparation method thereof of green glaze
Technical field
The present invention relates to ceramic fields, and in particular to a kind of formula and preparation method thereof of blueness glaze.
Background technique
Green glaze is the famous conventional color glaze of Chinese porcelain, and also known as " celadon glaze ", the green glaze in ancient times south, is the earliest face of porcelain
Color glaze, so-called " green glaze ", color is not pure blueness, is had: bluish white, reddish black, pale blue, plum green, pea green, pea green, emerald green blueness etc.,
But some dark greens how much can be glowed, meanwhile, often by green, green, blue three-color, one is referred to as " cyan " ancients, such as
Perhaps weighing apparatus " drink stream vegetarian say porcelain " claims: " old china is still green, it is all it is green also, Lan Ye, it is all included with blueness." in Liu Zifen " bamboo plantation Tao Shuo "
Say: " cyan is a kind of, often with it is blue mutually mixed, the sun shines again after the rain, the blueness of an ancient unit of weight kiln, first kiln, all close blue " " only thousand peaks in emerald colour, plum green,
It is pea green, be for pure green ear.This indigo plant of the colour of sky is sometimes blueness ".
But present porcelain green glaze for using when firing usually requires higher temperature and could be burnt into, and fires simultaneously
Green glaze color out is generally all dimer.
Summary of the invention
The purpose of the present invention is to provide a kind of formulas and preparation method thereof of green glaze, solve the firing that existing green glaze needs
Temperature is excessively high, and burns out the typically more dim problem of rear color.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of formula of blueness glaze, including following raw material: potassium feldspar, albite, quartz, dolomite, kaolin and talcum.
It is fired using dolomite, since dolomite is compared to calcite, contains magnesium elements, and magnesium is having oxygen
In the case where be easy to generate magnesia, fluxing agent can be played the role of, therefore it is lower to make to fire required temperature, using potassium feldspar
With two kinds of feldspar mixing of albite, the transparency of albite is good, solution high temperature viscosity is small, varies with temperature fastly, and potassium feldspar is burnt
It is wider at temperature range, can make after the two mixing glaze when firing variation more evenly, after firing, glaze colours just more evenly, and color
More highlighted, the effect burnt out is good.
As present invention further optimization, the mass fraction of the raw material is as follows: 23-28 parts of potassium feldspar, albite
15-22 parts, 23-28 parts of quartz, 15-20 parts of dolomite, 5-10 parts of kaolin, 3-7 parts of talcum.
As present invention further optimization, the mass fraction of the raw material is as follows: 24-27 parts of potassium feldspar, albite
17-21 parts, 23.5-26.5 parts of quartz, 16-19 parts of dolomite, 7-9 parts of kaolin, 3.5-6.5 parts of talcum.
As present invention further optimization, the mass fraction of the raw material is as follows: 24.5-26 parts of potassium feldspar, sodium are long
18-20.5 parts of stone, 24-26 parts of quartz, 16.5-18.5 parts of dolomite, 7.5-8.8 parts of kaolin, 4-6 parts of talcum.
As present invention further optimization, the mass fraction of the raw material is as follows: 24.8-25.5 parts of potassium feldspar, sodium
19-20.4 parts of feldspar, 24.5-25.5 parts of quartz, 16.6-18 parts of dolomite, 7.7-8.5 parts of kaolin, 4.5-5.6 parts of talcum.
As present invention further optimization, the mass fraction of the raw material is as follows: 25 parts of potassium feldspar, albite 20
Part, quartzy 25 parts, 17 parts of dolomite, 8 parts of kaolin, 5 parts of talcum.
Further include as present invention further optimization, in the raw material 2-4 parts of mass fractions chrome ore, 1-3 parts
The plant ash of mass fraction.
Joined chrome ore is because containing Cr2O2 in chrome ore, and Cr2O2 can be used as colorant under high temperature, instead of
Fe2O3 reduces the use of colorant, while the plant ash calcium P elements rich in being added in this way, can be used as fluxing agent,
The suspension having in glaze slip can reduce the high temperature viscosity of glaze and the melting temperature of further reduction glaze, but also have
Opaque has facilitation to chun glaze split-phase.
A method of green glaze is prepared by any of the above-described green glaze formula, includes the following steps: a, grind raw material
Grinds, the time of grinding are 48 hours;B, it is filtered after the completion of grinding, is subsequently placed in shady place and dries.
Grinding 48 hours is to adequately grind uniformly, and In Shade to dry rather than dry be then in order to prevent
Ingredient in raw material occurs oxidation reaction in drying and generates impurity, reduces the quality burnt out.
Compared with prior art, the present invention can at least reach one in following beneficial effect:
1. melting temperature is lower, 1290 DEG C can be reduced to from 1400 DEG C, the green glaze color burnt out be evenly distributed and brightness more
It is high.
2. joined chrome ore and plant ash in raw material, the melting temperature of glaze can be further reduced, and can be reduced
The use of colorant.
3. the green glaze quality that grinding sufficiently, is burnt out is high.
