Slow heating, kiln were warming up to firing temperature from 1100 DEG C through 3-4 hours, and small in firing temperature guarantor 1-2
When；
Chilling cooling, kiln are cooled to 400 DEG C through 1-2 hours, from firing temperature；
Slow cooling, kiln were cooled to kiln discharge after the room temperature stage from 400 DEG C through 0.5-1 hours.
According to the method described above, the dark metal glaze ceramics of environmental-friendly lead-free are made, for dark metal glaze ontology at black, surface is substantially unglazed
It is bright, its physicochemical property measured using vancometer and spectrophotometric color measurement instrument are as follows: glaze glossiness: 33%, the glaze coefficient of expansion:
155×10- 6/ DEG C, glaze can reflect the dizzy shape after the ferroso-ferric oxide oxidation of the metal such as black of black color under the illumination
Hot spot meets light side view, and may be seen indistinctly light colourful aperture, and light is soft, rich in color.
The dark metal glaze ceramics of environmental-friendly lead-free provided by the invention, with the gas in reasonable raw material proportioning and control sintering process
Atmosphere and temperature, the dark metal glaze body color burnt out in black or grey dark-coloured system, surface substantially without light, illumination it
Lower glaze can reflect the dizzy shaped laser spot after the ferroso-ferric oxide oxidation of the metal such as black of black color, meet light side view, indistinctly may be used
See light colourful aperture, light is soft, rich in color；The production work of the dark metal glaze ceramics of environmental-friendly lead-free of the invention
Skill uses the group of a variety of oxidants such as manganese oxide, iron oxide, copper oxide, nickel oxide, cobalt oxide, tungsten oxide, niobium oxide in raw material
Color development is closed, the method that " slow heating " is used in glaze sintering process uses the method for " slow cooling " in High-temperature cooling,
It avoids being quickly cooled down, makes the oxidant in glaze that fine crystals be precipitated during slow cooling, be evenly distributed in the table of glaze
Face.
It above are only the specific embodiment of the present invention, but the design concept of the present invention is not limited to this, all benefits
It is made a non-material change to the present invention, should all be belonged to behavior that violates the scope of protection of the present invention with this design.
