3. a kind of leopard figure glaze ceramic process according to claim 2, it is characterised in that: sintering range of the present invention is wide
The application of leopard decorative pattern glaze, includes the following steps:
(1) ground coat enamel specific gravity is adjusted to gravity Baume 1.28-1.36, is 900-1100 DEG C of range in sintering temperature using glaze method
Between ceramic body on glazing 1.0mm-1.3mm；
(2) overglaze specific gravity is adjusted to gravity Baume 1.52-1.63, using glaze method, glazing on the basis of step (1) ground coat enamel
0.9mm-1.1mm；
(3) composite mineralizer raw material specific gravity is adjusted to gravity Baume 1.08-1.26, using glaze method, in the base of step (2) overglaze
Glazing 0.4mm-0.8mm on plinth；
(4) will step (3) resulting product drying after be packed into electric furnace, according to heating curve: with heating rate be 1.0 DEG C -1.5 DEG C/
Min, from room temperature to 350 DEG C -500 DEG C；With heating rate for 2.0 DEG C -3.0 DEG C/min, from 500 DEG C of -650 DEG C of heatings 800
℃-900℃；With heating rate for 0.4 DEG C -0.8 DEG C/min, 910 DEG C -1100 DEG C are warming up to from 800 DEG C -900 DEG C；(1040
DEG C -1100 DEG C) ± 5 DEG C when, keep the temperature 120-150min, finally open fire door and carry out cooling to obtain leopard figure glaze；
Cooling as described above is to open the gap fire door 3-8cm, and control cooling rate is 8 DEG C -10 DEG C/min, from (1040 DEG C -
1100 DEG C) ± 5 DEG C be quickly down to 800 DEG C -900 DEG C, then micro- wicket that closes carries out being naturally cooling to room temperature to 1-3cm.
