For example, the overflow of oily pigments leads to blurred picture layers, and some pigments are not bright enough; the pastels and other pigments prepared with water, kerosene, etc., are not rich enough in color levels; ceramic floating color technology also has certain defects: ceramic works drawn using it After firing, although it can form a certain concave-convex color image on the porcelain surface, it can only be a dot-like three-dimensional effect, and the painted area will expand, and it will cause cracks in the picture when the color is baked.

[0039] The present invention also provides a method for preparing the Nijincai gold foil patch described in the above technical solution, comprising the following steps:
[0040] a) After the gold hammer is ground into gold foil, and the brass hammer is ground into copper foil, the gold foil and copper foil are cut into pieces, mixed and put into a crucible to heat and melt to obtain a melt; then the melt is cooled and taken out, Hammering into gold foil with a thickness of 0.1mm~0.5mm;
[0041] b) Divide the gold foil obtained in step a) into seven pieces of length×width (8cm~12cm)×(4cm~6cm), and then put the seven-color ceramic paint into seven pieces of gold foil according to the color and wrap them up. Repeatedly kneading and hammering to obtain metal wires of seven colors; finally, the seven colors of metal wires are twisted into spiral strips and hammered to obtain neon gold color gold foil patches.
[0042] In the present invention, firstly, the gold hammer is ground int...
Embodiment
[0080] (1) Take a gold hammer with a purity of 99.99% and grind it into gold foil, take a brass hammer and grind it into copper foil, cut the gold foil and copper foil into pieces, mix them according to the mass ratio of 8.3:1.7 and put them in a crucible and heat until Melt at 1080°C to obtain the melt, take it out after cooling, and hammer and grind it into seven gold foils with a thickness of 0.3mm and a length and width of 10cm×5cm.
[0081] (2) Use a small spoon to scoop 2g each of red, orange, yellow, green, blue, blue and purple ceramic paints into the gold foil, then roll the gold foil containing the pigments into cylindrical shapes, and roll them on Get seven gold foil paint sticks at both ends; then use the gold foil hammer tool to knead and hammer repeatedly to make metal wires with a diameter of 1mm; finally twist the seven-color metal wires into spiral strips, and then hammer them Formed into a neon gold color gold foil patch with a thickness of 0.05mm.

Abstract
The invention provides a neon-colored gold foil patch and its preparation method and application. The neon-colored gold foil patch is formed by hammering gold foil and seven-color ceramic paint; the gold foil is composed of a mass ratio of (8.3 ~7.3): (1.7~2.7) composed of gold and brass; the colors of the seven-color ceramic painting pigments are red, orange, yellow, green, blue, blue and purple respectively. Compared with the prior art, the neon gold color gold foil patch and its mordant agent provided by the present invention are suitable for neon gold color painting and neon gold overpainting. The seven-color rainbow halo is looming; it is specifically applied in the neon gold color painting and neon gold color overlay painting of ceramics. The visual effect of neon color gold greatly improves the artistic appreciation and commercial value of ceramic utensils.
Description
technical field [0001] The invention relates to the technical field of ceramic handicrafts, and more specifically relates to a neon gold color gold foil patch and a preparation method and application thereof. Background technique [0002] The painted decoration process of ceramics can be divided into overglaze color, in-glaze color and underglaze color. Among them, the overglaze color is divided into several categories such as ancient color, pastel color, new color, floating color, etc. Overglaze color is one of the main decorative techniques of ceramic handicrafts. Various patterns are drawn on the glazed surface of the ceramic vessel, and then baked in a kiln. There are three methods of underglaze color: one is to paint on the plain body, cover it with transparent glaze, and fire it once at high temperature; into porcelain; the third is to glaze the blank body, first bisque-fire it at a temperature of about 800°C, paint on the biscuit-fired blank body, then spray a thin ...
