When heat preservation 1~2 is small at this temperature, kiln discharge after cooling is Nixing pottery device.
Pottery is one of five big kiln porcelain of Song Dynasty, and the treasure in Han nationality's tradition technology in producing porcelain is referred to as national treasure, rarity,
It is world-famous for unique transmutation art.The transmutation phenomenon of pottery refers to chun glaze melt-flow at high temperature, milkiness and coloring
Staggeredly changing for complexity occurs for color, and glaze colours is made to become bright and colourful, and purple, red, blue, white friendship is mutually set off, and gives people one kind greatly certainly
So fast changing beautiful impression.Pottery transmutation art is that the wound of rough flambe burns till work(, is able to the flowing at high temperature glaze
Trace shows the magnificent color glaze with special aesthetic feeling and artistic temperament and interest occur with reality.This transmutation skill of pottery
Art changes successive dynasties porcelain that glass texture for covering all at one glance, and the distinctive natural beauty of porcelain, artistic beauty and lofty reason
Think that U.S.A combines together, create riot of color and the art piece with individual style.
To enhance the decorative effect of Nixing pottery, Nixing pottery and pottery are combined, retaining traditional Nixing pottery feature
On the basis of, addition chun glaze fires the mud Xing Juntao formed, can not only retain the antique traditional transmutation feature of Nixing pottery, but also have an ancient unit of weight
The color and luster of porcelain is sparkling and crystal-clear, can greatly enhance the properties of product and artistic value of Nixing pottery.But the chemistry of Nixing pottery green body and chun glaze
Composition difference is larger, and chun glaze is incompatible with green body, and the body-glaze intermediate layer thickness formed is only 15~20 μm, and interlayer is dredged
Pine, by substantial amounts of stomata and bulky grain, be very easy to occur to deform, burst, peeling, sucking the defects of.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation process of mud Xing Juntao, among finished product base glaze obtained
Thickness and densification so that glaze-body bonding is close, does not crack, not peeling.
Technical solution provided by the invention is there is provided a kind of preparation process of mud Xing Juntao, including preparing blank, green body
Shaping, body drying, green body decoration and green body are fired, and the green body decoration is one layer of low temperature glaze of application on dry base substrate；Institute
Raw material of the low temperature glaze including following parts by weight is stated to be made：50~60 parts of quartz, 6~10 parts of calcite, 8~15 parts of borax, feldspar 8
~12 parts, 2~5 parts of spodumene, 3~5 parts of cordierite, 1~3 part of copper oxide, 3~5 parts of zinc oxide, eastern 2~3 parts of mud, western mud 1~
2 parts.
The addition of quartz is mainly to provide SiO2, the mechanical strength and hardness of glaze are improved, and reduces the coefficient of expansion of glaze；
The addition of calcite improves the hardness and reflecting feel of glaze primarily to provide CaO.And CaO and SiO2With reference to life
Into glass, the binding ability of base glaze can be enhanced；
Borax is strong cosolvent, substantially reduces the sintering temperature of glaze, and the sintering temperature and green body for making glaze are adapted, boron
Sand can also reduce the coefficient of expansion of glaze so that the coefficient of expansion of glaze is less than green body, substantially reduces glaze and splits phenomenon；
Potassium feldspar provides alkali metal, is strong cosolvent, substantially reduces the melting temperature of glaze, has glaze good transparent
Degree can also reduce the coefficient of expansion of glaze；
The reaction of cordierite and spodumene is violent, contributes to the rapid development in interlayer, promotes interpenetrating for green body and glaze,
Increase the thickness in interlayer, improve the associativity of base glaze；
Zinc oxide, copper oxide are respectively provided with certain solvent effect, reduce glaze melting temperature, reduce the coefficient of expansion.
Eastern mud and western mud are clay, to improve the adhesiveness of glaze and green body.
Due to the collective effect of above-mentioned dispensing so that the sintering temperature of glaze and green body is with being adapted, and the coefficient of expansion omits
Less than green body, the binding ability of base glaze is substantially increased.
The thickness of the low temperature glaze layer is 0.5~1mm.
In green body fires this process, it is divided into three-stage firing, initial stage is fired, to raise 80~100 DEG C per hour
Temperature is risen to 500~600 DEG C by heating rate, and the heating rate in this stage is relatively low, primarily to slowing down clay mineral
Dehydration shrinks so as to slow down green body, prevents blank cracking；
Mid-term is fired, temperature is raised to 900~950 DEG C with the heating rate for raising 200~250 DEG C per hour, this rank
The heating rate of section is very fast, this is because the moisture in this stage green body and glaze layer excludes substantially, accelerating speed will not cause
The cracking of green body and glaze layer keeps the temperature 1~2h at a temperature of this, it is ensured that SiO at 900~950 DEG C2And Al2O3It is formed enough
Aluminium silicon spinel (2Al2O3·3SiO2), and aluminium silicon spinel is made to have time enough to be uniformly distributed in body-glaze intermediate layer, make
Body-glaze intermediate layer thickens and fine and close, without big particle and stomata, mainly based on small crystal grain and glass phase, by green body
It combines closely with glaze, improves flexural strength, thermal shock resistance, crack resistance energy.
The later stage is sintered, the heating rate to raise 100~150 DEG C per hour rises to 1000~1020 DEG C, is formed at this time big
The mullite of amount, extend soaking time to 3~4 it is small when, forming the new amount of liquid phase of mullite will greatly increase, and have enough time
It is uniformly distributed in body-glaze intermediate layer so that body-glaze intermediate layer thickness greatly increases and densification, and intensity greatly enhances, so as to improve
The binding ability of base glaze.Simultaneously because firing temperature is only 1000~1020 DEG C, less than Nixing pottery routine firing temperature, avoid
Long-time heat preservation causes the problem of Nixing pottery product burning.
Preferably, above-mentioned green body firing is that the green body decorated is sent into kiln, temperature is stepped up, first with every
Temperature is risen to 550~600 DEG C by the heating rate that hour raises 80~100 DEG C, then to raise 200~250 DEG C of liter per hour
Temperature is raised to 925~950 DEG C by warm speed, keeps the temperature 1.5~2h at such a temperature, then to raise 100~150 DEG C per hour
Heating rate rises to 1000~1020 DEG C, and when heat preservation 3.5~4 is small at such a temperature, kiln discharge is to get mud Xing Juntao after cooling.
Compared with prior art, the invention has the advantages that：
1) glaze sintering temperature of the invention is adapted with green body, and the coefficient of expansion is slightly below green body so that among base glaze
Thickness and densification, can effectively avoid glaze split, peeling phenomena such as appearance.
