BRIEF DESCRIPTION OF THE DRAWINGS FIG.

Disclosure of the Invention The present invention relates to a method for preventing the cracking and dropping of silver on the inner surface of a ceramics while suppressing bacteria and enhancing the deodorizing power for removing bacteria and odors, A method for manufacturing ceramics is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

Before the present invention is described, the production steps are: a forming step (S100) of molding a product by kneading clay in a semi-dry state after kneading; A preliminary step (S200) of completely drying the material and pulverizing the material in a kiln at 850 ° C; A step S300 of applying a glaze to the surface of the superimposed article; A chaebol step (S400) of energizing the spent material at 1250 ° C; After the chaebol step S400, a mixture of silver and water which has been diluted with the liquid is thinly spread with the inner surface brush of the chaotic material, and then the mixture is firstly fired, and the mixture is again fired on the surface of the primarily fired product A sintering step (S500) in which a thin layer is applied and then a second sintering is performed; A glossing step (S600) of emitting light to the inner surface of the fired body; Wherein the inner surface of the article is coated with a candle and the glaze is applied to the outer surface of the article in the applying step (S300), and the glaze embedded in the outer surface of the article is sponge Or a cloth to wipe the glaze, and the mixture in the firing step (S500) is diluted 1: 1 with silver and water, the first firing is performed at 650 ° C, the second firing is performed at 850 ° C , And the polishing step (S600) is configured to wipe the water flowing in the inner surface of the fired body by wiping it with a rubbing cloth or a rough cloth in one direction.

Generally, various kinds of ceramics such as a soup bowl, a spoon can, a cup, a mug, and the like are provided. As an embodiment of the present invention,

(Example)

(1) Forming step (S100)

The molding step S100 is performed by kneading using ordinary clay, followed by bending in a semi-dry state to form a mug. The shape of the mug (cup) and the size of the mug will be similar to that of a typical cup or the like.

(2)

In the preliminary step S200, the mug is completely dried and then dried in a kiln at 850 ° C.

(3) Sustaining Step (S200)

The step of applying a glaze to the surface of the mug is characterized in that the inner surface of the mug is coated with a candle or paraffin and the outer surface is glazed with a glaze embedded on the outer surface of the article, This is to wipe the glaze with a cloth so that silver is applied to the inner surface of the finished mug.

For the purpose of applying glaze only to the outer surface in the refining step and coating the candle or paraffin without glaze on the inner surface, food is contained in the finished mug (mug), and if necessary, It is also possible to apply glaze to the inner and outer surfaces of the mug.

④ Chaebol stage (S400)

The sieved material (mug) is massed at 1250 ° C so that the candle or paraffin put on the inside of the mug can be evaporated.

(5) Firing step (S500)

The sintering step (S500) is a key step of the present invention. The sintering step (S500) is a step of the present invention in which a mixture obtained by diluting silver and water in liquid at a ratio of 1: 1 after the chaebol step (S400) And then the mixture is again thinly applied to the surface of the primary sintered body and then the secondary sintering is performed again at 850 ° C to finally obtain the completely sintered body Thereby forming a mug.

That is, in the firing step (S500), the mixture is fired on the inner surface of the mug and then fired, and the mixture is baked again and then fired to form cracks of silver on the inner surface of the finally finished mug So that it can be used for a long period of time.

Although it has been described that firing is performed twice in the firing step (S500), it may be performed twice or more if necessary.

Test Items Kinds One time firing 2 times plasticity Experiment on durability The material (mug) Temperature 650 ° C 1 time temperature 650 ° C
2 times Temperature 850 ° C result 8.5 9.6 [Average results for the durability of the silver on the surfaces of the first and second fired products]

Table 1 shows the average value of the results of several times of durability such as cracking and falling of a mug (a mug) through one firing step and a mug with a repeated firing step in the case of Table 1, The durability of the finished silver through the one firing step was 8.5, and the durability of the silver after two firing steps was 9.6, indicating that the durability of the silver fired twice more than once was higher.

In other words, according to the firing provided by the present invention, the durability of silver is high, so that cracks do not easily occur and do not fall off, so that they can be used for a long period of time and economic efficiency can be improved.

(6) Luster Step (S600)

When the firing step (S500) is performed by wiping the water flowing on the inner surface of the fired article by wiping with water or a rough cloth in one direction, the surface of the object (mug) (S600). However, since only one direction is wiped, it is possible to add visually beautiful.

According to the method of manufacturing ceramics in which silver is incident on the surface of ceramics using silver according to the present invention, it is possible to keep the original purpose of the ceramics as it is, and at the same time, And it is a useful invention having high economic efficiency that can be used for a long time because it can prevent cracks and falling of silver on the surface of the completed ceramic through repetitive firing in the firing work.
