In a preferred embodiment, the inspection apparatus is a CT scanner or a nondestructive inspection apparatus.
At present, no prior art discloses implanting an implant different from the ceramic product material to achieve the anti-counterfeiting effect in the chinaware product. It is generally accepted by those skilled in the art that chinaware articles cannot be implanted with an implant other than chinaware material to provide anti-counterfeiting benefits. This is because, when the anti-counterfeiting material is embedded in the material body of such products, the anti-counterfeiting material needs to be embedded before the material body is fired, and then the anti-counterfeiting material is obtained by firing and molding. However, since the density of the chinaware material is different from that of the security material, the shrinkage rate of the two materials is different during the firing process, and the implant will bulge out after the firing and cooling, thereby changing the appearance of the container wall and even breaking.
As is well known to those skilled in the art, porcelain is not contaminated with impurities during firing, and if contaminated with impurities, cracking may occur, resulting in unsuccessful firing. Therefore, those skilled in the art have long attempted to avoid the infiltration or incorporation of foreign matter into the porcelain material to prevent firing failures.
The invention discovers for the first time through experiments that the purple sand material can be just selected, and the anti-counterfeiting material is implanted into the purple sand material body, even if the materials are different and the densities are different, experts in the field are surprised that the purple sand container body can still keep the original shape after being fired, the anti-counterfeiting material is not protruded, and the container body is not cracked. This is the first discovery and initiative of the present invention.
Of course, if the purple sand is replaced by porcelain, glass or the like, the result is failed.
Preferably, when the purple sand container is implanted with metal or alloy or nonmetal material, the melting point or firing temperature of the implant material is selected to be within a certain range.
The purple sand container obtained by the method of the invention has the advantages that the anti-counterfeiting material with the density different from that of the purple sand container is implanted in the container body, and when the anti-counterfeiting material is scanned by an instrument, the displayed colors are different, so that the size, the shape, the direction and the like of an implant can be identified, and the anti-counterfeiting purpose is achieved. Such anti-counterfeiting purposes are essentially impossible for counterfeiters to reproduce. Because the orientation of the fired security material is varied. Even though a counterfeiter imitates the anti-counterfeiting implantation of any commercially available purple sand container in an identification mode, for example, the counterfeiter imitates the exact anti-counterfeiting material size, shape, position and the like. However, the anti-counterfeiting material in the purple sand container is implanted before firing, and in the firing and forming process of the purple sand container, due to the effects of thermal expansion and cold contraction, the implant in the purple sand container has some complicated unpredictable changes such as volume change, displacement, uncertain bubble elimination and the like, so that the anti-counterfeiting material is necessarily different from the initial implantation position of the anti-counterfeiting material. Therefore, no one can simulate the completely consistent purple sand container containing the anti-counterfeiting material.
In another aspect, the invention provides a preparation method of the anti-counterfeiting purple sand container, which comprises the following steps:
(1) Performing yard weathering on the purple sand mud raw material, then grinding and sieving, blending, adding water, uniformly mixing, and then primarily refining into mud serving as cooked mud;
(2) Uniformly stirring the mixture by using a vacuum pug mill before using the cooked mud to obtain blank-making pug for later use;
(3) Manually beating the pug into pug pieces, sticking the pug pieces to a mould, adding an anti-counterfeiting material to implant the pug pieces into a container body, and beating and forming the pug pieces to obtain a blank body;
(4) And (3) drying the blank body, and then carrying out biscuit firing: putting the mixture into an oven for drying, putting the mixture into a kiln for firing, and obtaining a finished product of the purple sand container after firing;
(5) And (4) after the finished product container is processed, feeding the finished product container into the kiln again for firing, and taking out the tea container after firing is finished to obtain the purple sand container product.
The invention has the following beneficial effects:
1. when the purple sand container is manufactured, anti-counterfeiting materials meeting specific requirements are implanted into the container body of the purple sand container, and after the purple sand container is manufactured, the anti-counterfeiting materials are detected by instruments such as a CT scanner and a nondestructive flaw detector, so that the implant and the position of the implant in the container body can be visually distinguished, and the anti-counterfeiting purpose is achieved.
The invention has the breakthrough point in thinking that not only the simple characteristics of density and melting point of the anti-counterfeiting implant are utilized, but also no one thinks that another particle substance is implanted into the main body material of the anti-counterfeiting implant for anti-counterfeiting, and the invention is just suitable for the purple sand material, and the anti-counterfeiting material is implanted into the purple sand material body, so that even if the materials are different and the densities are different, experts in the field are surprised that the container body of the fired purple sand container can still keep the original shape, the anti-counterfeiting material is not prominent, and the container body is not cracked. This is the first discovery and initiative of the present invention. After the implant is implanted, the surface characteristics of the device and the main body material of the device are not changed.
Compared with a surface anti-counterfeiting mode or a mode of changing the formula of a main material, the anti-counterfeiting liquid has high anti-counterfeiting concealment performance, is not easy to copy and has great advantages.
2. In addition, the purple sand container is safe and nontoxic.
In conclusion, the anti-counterfeiting method for the purple sand container has better application prospect.

The anti-counterfeiting dark-red enameled pottery of the invention is characterized in that: the anti-counterfeiting material non-metal aluminum oxide spheres which have the density difference with the self material of the pot and the firing temperature of more than 1350 ℃ are implanted into the dark-red enameled pottery. After the dark-red enameled pottery is manufactured, scanning detection is carried out through a CT scanner, and nonmetal aluminum oxide particles implanted in the kettle body can be visually distinguished.
The preparation method of the dark-red enameled pottery comprises the following steps:
(1) Removing waste soil, included stones and relatively obvious ferro-sulphur minerals from the mined purple sand mud serving as a raw material, carrying out yard weathering, grinding and sieving after forming bean-shaped particles, adding water to refine the mixture into blocks, and placing the blocks for two months to serve as cooked mud for later use;
(2) Before use, the cooked mud needs to be put into a vacuum pug mill and stirred uniformly, and pug for blank making is obtained after kneading for later use;
(3) Pressing the pug in a pressing machine to obtain 3mm thick pug slices, measuring according to the specification of the kettle, cutting off the unnecessary part, sticking the pug slices on a mold, adding 55% mass percent of pug slices with the volume density of 2.8g/cm 3 Alumina balls with the diameter of 2.5mm are implanted into the pot handle mud, then the mud pieces are flapped and formed, and then polishing treatment is carried out by a polishing machine;
(4) Before firing the dark-red enameled pottery, the green body needs to be dried, and when the dark-red enameled pottery is placed in a kiln for firing, the firing temperature is controlled to be 1150-1200 ℃, and then a finished product is obtained;
(5) After the product is processed, the product is sent into the kiln again to be fired, the highest temperature is not more than 1350 ℃, and the required product is obtained;
(6) The manufactured dark-red enameled pottery is detected by a CT scanner, and a scanning pattern is shown in figure 6.
The results show that: the anti-counterfeiting ball made of the non-metallic material aluminum oxide which meets the conditions is implanted into the product, and the position of an anti-counterfeiting object can be clearly distinguished through detection of the CT scanner, so that the dark-red enameled pottery achieves the anti-counterfeiting effect.
Comparative example 2
Except that the mass% in the experimental step (3) of example 5 was 55% and the bulk density was 2.8g/cm 3 The aluminum oxide particles are changed into 20 percent by mass and 2g/cm by volume density 3 The same procedure as in example 5 was repeated except for the use of the alumina fine particles of (1).
As a result: as shown in FIG. 7, the alumina particles implanted in the dark-red enameled pottery can not meet the specific requirements (the mass percentage of alumina is more than 50%, and the volume density is 2.5 g/cm) 3 Above), no implant in the pot body can be detected by the non-invasive detector. So that the dark-red enameled pottery can not achieve the anti-counterfeiting effect.
Therefore, the non-metallic material is required not only for its material type but also for its mass percentage and volume density.
The anti-counterfeiting dark-red enameled pottery of the invention is characterized in that: the zirconia wafer which is a non-metal anti-counterfeiting material and has the density difference with the material of the dark-red enameled pottery and the firing temperature of more than 1350 ℃ is implanted into the dark-red enameled pottery. After the dark-red enameled pottery is manufactured, scanning detection is carried out through a CT scanner, and nonmetal zirconium dioxide implanted in the kettle body can be visually distinguished.
The preparation method of the dark-red enameled pottery comprises the following steps:
(1) Removing waste soil, included stones and relatively obvious pyrite minerals from the mined purple sand mud serving as a raw material, performing yard weathering, grinding and sieving the purple sand mud after the purple sand mud is formed into beans and filled with particles, adding the beans and refining the beans into blocks, and placing the blocks for two months to serve as cooked mud for later use;
(2) Before use, the cooked mud needs to be put into a vacuum pug mill and stirred uniformly, and pug for blank making is obtained after kneading for later use;
(3) Making the pug processing factory into 3mm thick pug, measuring according to the specification of the kettle, cutting off the unnecessary part, sticking the pug onto the mold, adding 35% mass percent and 4g/cm bulk density 3 Zirconium dioxide round piece with diameter of 2.5mm is implanted into the pot handle mud. Then beating and forming the mud pieces, and polishing with a polishing machine;
(4) Before firing the dark-red enameled pottery, the green body needs to be dried, and when the dark-red enameled pottery is placed in a kiln for firing, the firing temperature is controlled to be 1150-1200 ℃, and then a finished product is obtained;
(5) And (4) after finishing the finished product, feeding the finished product into a kiln again for firing, wherein the maximum temperature is not more than 1350 ℃, and obtaining the required product.
As shown in FIG. 8, the product is implanted with a non-metallic zirconium dioxide anti-counterfeiting object wafer meeting specific conditions, and the anti-counterfeiting object position can be clearly identified through detection of a CT scanner, so that the prepared dark-red enameled pottery achieves the anti-counterfeiting effect.
Comparative example 3
Except that in the experimental step (3) of example 6, the mass percent was 35%, and the bulk density was 4g/cm 3 The zirconia fine particles are replaced by 20 percent by mass and the volume density is 2g/cm 3 Zirconium dioxide particles, the other steps are the same as in the example6。
As shown in FIG. 9, the non-metallic zirconium dioxide material implanted into the body of the dark-red enameled pottery does not meet the specific requirements (the mass percent of zirconium dioxide is more than 30%, and the volume density is more than 3%), so that the implant can not be detected by a nondestructive detector, and the anti-counterfeiting effect of the dark-red enameled pottery prepared by the method can be achieved.
Therefore, not all non-metal materials are available, and metal meeting certain conditions can be used for anti-counterfeiting of the dark-red enameled pottery. The implanted anti-counterfeiting material is different from the material of the dark-red enameled pottery, and the density of the implanted anti-counterfeiting material is different; however, the non-metallic material meeting the density requirement can be used as the anti-counterfeiting material of the dark-red enameled pottery only when the firing temperature of the non-metallic material meets 1350 ℃, so that the mass parts and the volume density of different non-metallic materials can meet specific requirements.
