The invention provides a method for optimizing a technology for painting,
glazing and firing porcelain on a
crystal surface, the optimized
crystal belongs to a high-temperature-resistant material which is hard in texture, high in density and poor in
adhesive force and has very high requirements on coloring and
glazing of
underglaze color, and pigments and
glaze materials with strong
adhesive force need to be manufactured, firstly, the surface of an optimized
crystal object is polished to be in a moderate frosted state; then,
pigment with moderate
water content and extremely fine
granularity is used for drawing, first-time fixation firing is carried out after coloring, and the highest firing temperature is 600 DEG C; after cooling,
glaze is sprayed for 1-2 times for secondary firing, the temperature is selected according to the
glaze, repeated coloring and
glazing and repeated firing can also be performed according to creation requirements, and the highest firing temperature does not exceed 1650 DEG C. And the peak high-temperature time is controlled to be 10-20 minutes, so that the effect of fusing the glazing color and the crystal surface can be realized. According to the method, the defects that in the prior art, crystal and glaze are difficult to combine, and the firing effect is not ideal are overcome, and the exquisite and lasting crystal surface decoration effect is achieved.
