Under glaze, sprinkle the preparation method of color ceramic
Technical field
The invention belongs to under-glaze decoration ceramic goods and make field, be specifically related to sprinkle under a kind of glaze the preparation method of color ceramic, be particularly useful for making the different ceramic art works of porcelain plate, porcelain dish and other type.
Background technology
Underglaze colour is the main decorative means of the one of ware, is above to draw various decorative patterns with colorant at the molded biscuit drying (being semi-finished product), then covers with white clear frit or other light cover-coat enamels, once-firing. Pattern after burning till is covered below by the glaze film of layer of transparent, surface-brightening is soft, smoothly do not protrude, seem sparkling and crystal-clear bright, under tradition glaze, Ceramic Painting material is all water and glue modulation, but the colorant that glue modulates, its texture that can not well naturally trickle, can not form picture sense, can only be to hook line drawing, the freehand brushwork of Extension pen, point water, pick the forms such as flower and carry out artistic decoration, exist manufacturing speed slow, require the deficiencies such as high, common producer difficult control in short-term to decorating skill.
Summary of the invention
The object of this invention is to provide the preparation method of sprinkling color ceramic under the glaze that a kind of manufacturing speed is fast, decoration technique is simple and easy to control.
In order to realize goal of the invention, the technical solution used in the present invention is: the preparation method of sprinkling color ceramic under a kind of glaze, comprise the preparation of sprinkling color high temperature decorating colour under the making of ceramic material and glaze, it is characterized in that: under glaze, sprinkle color high temperature decorating colour and comprise formula A: frankincense oil 15%~25%, camphorated oil 35%~40%, kerosene 40%~45%, additional toner; Or formula B: frankincense oil 25%~35%, camphorated oil 65%~75%, additional toner; In ceramic material, add talcum and sodium humate; Carry out according to the following steps successively:
(1), put into electrical kiln baking after the moulded pottery not yet put in a kiln to bake of moulding is dry, cooling after 700 degrees Celsius to 1150 degrees Celsius barbecues;
(2), splash on moulded pottery not yet put in a kiln to bake surface sprinkling color high temperature decorating colour under glaze, more in addition flow fluid flows in the desired direction colorant on moulded pottery not yet put in a kiln to bake, formula A taking camphorated oil with kerosene as flow fluid, formula B, taking camphorated oil, alcohol as flow fluid, forms the beautiful picture trickling;
(3), show after beautiful picture at the colorant of splashing, then an apt word added to clinch the point the in addition overall picture of having painted;
(4), spray bluish white clear frit, become porcelain through 1300 degrees Celsius of left and right high-temperature firings, form the ceramic that sprinkles colour painting face under glaze.
Under glaze, sprinkling color carrier is moulded pottery not yet put in a kiln to bake, and quality is loose, if do not take the step 1 in the present invention, after absorbent solution, easily ftractures.
The colorant that glue modulates sprinkles the maturation of application on coloured silk on glaze, and it is to draw on the ceramic whiteware having burnt till, because the not absorbent solution of porcelain smooth surface after firing is easy to flow while splashing on ceramic whiteware, technology is relatively simple; And be applied directly under glaze sprinkle color upper, its texture that can not well naturally trickle.
In the present invention, by add talcum and sodium humate in ceramic material, can increase the hardness of pug and moulded pottery not yet put in a kiln to bake, reduce the water imbibition of moulded pottery not yet put in a kiln to bake simultaneously, and take steps 1, make moulded pottery not yet put in a kiln to bake surface reach certain density and intensity, solve under glaze and sprinkle color carrier moulded pottery not yet put in a kiln to bake, quality is loose, the problem easily ftractureing after absorbent solution, also coordinate with flow fluid by the colorant of selecting special formulation, realized the texture that naturally trickles, the object of the painting products that fast and convenient formation nature sky becomes.
Detailed description of the invention
Embodiment 1
By volume percentage frankincense oil 15%~25%, camphorated oil 35%~40%, kerosene 40%~45%, preparation colorant, taking camphorated oil and kerosene as flow fluid; Splash and on moulded pottery not yet put in a kiln to bake, naturally trickle texture picture;
1, in ceramic material, add talcum and grind, to increase the hardness of pug;
2, in moulded pottery not yet put in a kiln to bake moulding, add rotten sodium, strengthen the hardness of moulded pottery not yet put in a kiln to bake, reduce the water imbibition of moulded pottery not yet put in a kiln to bake, the intensity of favourable moulded pottery not yet put in a kiln to bake simultaneously;
3, moulding moulded pottery not yet put in a kiln to bake is put into electrical kiln baking after being dried, cooling after 700 degrees Celsius to 1150 degrees Celsius barbecues;
4, modulate under glaze and to sprinkle color high temperature decorating colour, splash on moulded pottery not yet put in a kiln to bake surface, more in addition flow fluid flows colorant, forms the picture of trickling, can not cause moulded pottery not yet put in a kiln to bake cracking because of absorbing flow fluid simultaneously;
5, make the colorant of splashing trickling in the desired direction on moulded pottery not yet put in a kiln to bake, show after beautiful picture, more in addition an apt word added to clinch the point the overall picture of having painted;
6, spray bluish white clear frit, become porcelain through 1300 degrees Celsius of left and right high-temperature firings, form the product that sprinkles colour painting face under glaze.
Embodiment 2
By volume percentage: frankincense oil 25%~35%, camphorated oil 65%~75%, taking camphorated oil, alcohol as flow fluid;
1, in ceramic material, add talcum and grind, to increase the hardness of pug;
2, in moulded pottery not yet put in a kiln to bake moulding, add rotten sodium, strengthen the hardness of moulded pottery not yet put in a kiln to bake, reduce the water imbibition of moulded pottery not yet put in a kiln to bake, the intensity of favourable moulded pottery not yet put in a kiln to bake simultaneously;
3, moulding moulded pottery not yet put in a kiln to bake is put into electrical kiln baking after being dried, cooling after 700 degrees Celsius to 1150 degrees Celsius barbecues;
4, modulate under glaze and to sprinkle color high temperature decorating colour, splash on moulded pottery not yet put in a kiln to bake surface, more in addition flow fluid flows colorant, forms the picture of trickling, can not cause moulded pottery not yet put in a kiln to bake cracking because of absorbing flow fluid simultaneously;
5, make the colorant of splashing trickling in the desired direction on moulded pottery not yet put in a kiln to bake, show after beautiful picture, more in addition an apt word added to clinch the point the overall picture of having painted;
6, spray bluish white clear frit, become porcelain through 1300 degrees Celsius of left and right high-temperature firings, form the product that sprinkles colour painting face under glaze.
