In the case where mentioned component and use above-mentioned raw materials, penniform furnace transmutation glaze can be made, be the life of people
Production increases more enjoyment, and the amount of dissolution of lead and cadmium is not detected in the furnace transmutation glaze, is used as ceramics and tableware for daily use
It decorates fool proof, ensure that the health of people's body.
In order to achieve the above objectives, the application also proposed the preparation method of above-mentioned feathery furnace transmutation glaze, specifically include as follows
Step:
(1) ground coat enamel glaze slip and overglaze glaze slip: the preparation of ground coat enamel glaze slip are prepared: ground coat enamel raw material wet ball grinding being sieved, is made
Ground coat enamel glaze slip, the specific gravity of control ground coat enamel glaze slip are 1.5-1.6g/cm3；The preparation of overglaze glaze slip: by overglaze material wet ball grinding,
Sieving, is made ground coat enamel glaze slip, and the specific gravity of control ground coat enamel glaze slip is 1.45-1.55g/cm3；
(2) glazing: ground coat enamel glaze slip equably being applied and is spread on ceramic biscuiting green body, is formed ground glaze layer, is dried in ground glaze layer
Overglaze glaze slip is applied again afterwards and forms cover coat on deposited ground glaze layer, glazing green body is made；
(3) green body is burnt into: glazing green body being roasted in oxidizing atmosphere, starting is with the heating of 120-150 DEG C/h speed, heating
To 1150-1180 DEG C, overglaze starts split-phase；Then continue to heat up with 40-70 DEG C/h speed, be warming up to 1250-1280 DEG C, heat preservation
20-60min, be finally cooled to room temperature to get.
Preferably, in step (2), when glazing, ground coat enamel glaze layer with a thickness of 0.2-0.5mm, overglaze glaze layer with a thickness of
0.1-0.3mm。
In the present invention, using Fe2O3And MnO2As colorant, suitable ceramic black element is added and is used as colour correction agent,
Under above-mentioned firing condition, feathery furnace transmutation glaze can be made ideally to show, firing temperature is especially limited to two sections
When, reach makes overglaze carry out split-phase first, forms the liquid phase of two kinds of different chemical compositions, and it is different to form two kinds of compositions after cooling
Vitreous enamel can be such that the color of ground coat enamel shows wherein the phase transparency is preferably, provide to there is penniform decorative pattern
Basic guarantee；Continue to heat up, maximum sintering temperature is made to reach 1250-1280 DEG C, overglaze starts to flow, and two-phase occurs staggeredly to mix
Phenomenon forms feathery furnace transmutation glaze after cooling.When firing temperature is lower than the lower limit of above-mentioned temperature range, ground coat enamel and overglaze cannot
Melting, glaze paint just will appear many pores, influence beauty completely；When firing temperature is higher than the upper limit of above-mentioned temperature range, bottom
Glaze and overglaze will be melted excessively, and plumage line will disappear, and the transmutation effect of anticipation is not achieved.
Further, overglaze is adversely affected to reduce organic matter in raw material, in step (1), is prepared in overglaze glaze slip
Before, precalcining is carried out to raw material zinc oxide and titanium dioxide first, precalcining temperature is 1200-1300 DEG C, soaking time 30-
60min.After completing precalcining, remaining organic impurities is disposed of in zinc oxide and titanium dioxide, avoids organic impurities by band
Enter into overglaze.
Further, to guarantee the smooth of glaze paint, in step (1), grit number is crossed when ground coat enamel glaze slip and overglaze glaze slip are sieved
It is 250 mesh, tails over as 0.08-0.12wt%.
Further, in step (2), the water absorption rate of the ceramics biscuiting green body is 12-15%.Water absorption rate within this range may be used
To guarantee glazed thickness, glazing defect is reduced.
