Description

CERAMICS MANUFACTURING METHOD

The present invention relates to a method of manufacturing ceramics, and more particularly, to a method of manufacturing ceramics by decorating clay on the surface of the ceramics body by drawing and firing the ceramics body with a cloisonna pigment.

Cilobo is literally craft made using colorful and colorful materials such as gold, silver, amber, transparent, coral, agate, and pearl. The cloisonne is a traditional craft which melts various glass materials on the basis of gold, silver and copper in a dictionary meaning and puts out a pattern.

Specifically, the cloisonne is a traditional metalwork that is made by applying a glassy cloisonne pigment on a base metal and then fixing it to a base metal by high temperature heat treatment at 700~820 ° C. The metal oxide (gold-red, silver- Opaque yellow color system, copper oxide green color system, etc.) have various colors through heat treatment and develop color with beautiful color together with the color of base metal, and they are used as various crafts and household goods or their ornaments.

Such cloisonne has excellent gloss, reflectance and refractive index, and is very beautiful in color, and has the advantage of design freedom and color expression, so it is used not only as a traditional ornaments but also as a decoration for various living things.

However, the above-mentioned cloisonne is formed on the metal material, and the cloisonne is not applied to the ceramics, and it is necessary to apply the cloisonne to the ceramics to enhance the quality of the ceramics and maximize the beauty.

However, when the clay is decorated with ceramics, the glaze applied to the surface of the ceramics due to the difference in thermal expansion between the ceramics, the glaze, and the cloisonne pigment during the heat treatment of the ceramics causes a peeling phenomenon, have.

A method of manufacturing a cloisonna pottery forming such a cloisonné decoration is disclosed in Korean Patent Publication No. 10-2013-0136897.

According to the method of manufacturing the Cloisonne ceramics described above, a space for the cloth to be decorated with the cloisonne is made, a water-repellent agent is applied to the scraped part so that the adhesive can adhere well to the space, (Second step) in which a gauze or embroidered cloth is adhered to a space to be decorated with a cloisonna by a glue (second step), a cloth is adhered with an adhesive, (The third step) for drying for a period of time (the third step), a sagging step (fourth step) for drawing a sack on the above-described porcelain when the bonded cloth is dried, a mixture of glue, glue and pigment, (The fifth step), which is followed by drying for 24 hours after the coloring process, and a coloring process (sixth process) for drying the coloring process for about 6 hours after the coloring process is completed, (7th step) in which the lacquer is applied to the painted figure evenly over two times and dried for 24 hours, and the rejuvenation process (the seventh step), in which the lacquer is applied, ), And a coating process (the ninth process) for finishing all the operations by performing the coating operation 2-3 times on the above figure after the re-finishing work.

Conventionally, in the method of manufacturing the cloisonna ceramics, the cloisonne is adhered to the ceramics body, and then the cloisonne is put on the bonded cloth by cloisoning the cloisonne, for example, It is not only difficult to mass-produce, but also the cost of the product is increased and the adhesive strength between the ceramic body and the cloisonne is easily lowered, so that the cloisonna is peeled off from the body of the ceramic article, resulting in defective products.

In addition, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flow chart of a method of manufacturing a ceramic according to an embodiment of the present invention, and FIGS. 2 and 3 illustrate an ornamental manufactured by a method of manufacturing a ceramic according to an embodiment of the present invention.

Hereinafter, a bag-like ornamental article will be described as an example of the ceramics 1, but the present invention is not limited thereto, and the method of manufacturing a ceramics according to the present invention can be applied to various articles such as porcelain containers, tableware, Leave.

First, a pottery body 10 in the form of a bag is formed by using a porcelain base, as shown in Fig. 2, in which a stilos decorating portion 20 is formed (S10). The ceramic body 10 can be formed by pressing the kneaded base material into a flat shape by pressing it into a bag-shaped mold or cutting it into a bag shape through a CNC milling machine.

The porcelain base is preferably made of a combination of at least one of clay, clay, stonite, zircon, feldspar, sericite and alumina.

Here, it is more preferable that the ceramic substrate is formed in a chemical composition ratio as shown in <Table 1> below.

<Table 1>

Next, the molded ceramic body 10 is dried (S20).

The ceramic body 10 is dried. When the drying of the ceramic body 10 is completed, the dried ceramic body 10 can be shaped and trimmed neatly.

Then, the remaining area of the dried pottery main body 10 excluding the stencil decorating part 20 is used as a ceramic glaze (S30). On the other hand, the reason why the remaining area of the ceramic body 10 excluding the cloisonne decoration section 20 is sour is that when the cloisonne decoration section 20 is coated with a glaze, the first cloisonel pigment and the second cloisonne pigment The glaze applied to the cloisonroom decorating section 20 at the time of firing is melted before the first cloisono pigment and the second cloisonne pigment so that the first cloisono pigment and the second cloisono pigment are stably And the first cloisono pigment and the second cloisono pigment can not be fused to the surface of the ceramics 1.

Here, it is preferable that the ceramic glaze component for the ceramics 1 is mixed at a ratio of 40 parts by weight of feldspar, 20 parts by weight of silicate, 30 parts by weight of limestone and 10 parts by weight of kaolin.

On the other hand, in this embodiment, the ceramics body 10 is described as being sown, but the souring process of the ceramics body 10 is not necessarily performed, but can be selectively performed.

Subsequently, the sintered ceramic body 10 is sintered at a temperature in the range of 1260 ° C to 1300 ° C (S40). By such a sintering at a high temperature, the ceramic body is sintered and the ceramic body 10 has a high strength.

The first cloisonob pigment is raised in one area of the cloisonroom decoration part 20 of the preliminarily fired ceramics body 10 (S50). When designing with the first cloisonne pigment, it is possible to express a more stereoscopic and beautiful color by allowing various colors to be naturally connected by the Bokashi technique which makes the border between color and color fade.

Here, a brief description of the cloisonne pigment will be given below.

Cloisonne pigments are vitreous particles that can be mixed and mixed together like paints, and even one color can have various levels of dark color, neutral color, and bluish color, and they are transparent, translucent and opaque. When making the cloisonne pigment from the manufacturer, the glaze and the oxidizing pigment are blended, put into a melting furnace, boiled at 1300 ° C, rapidly cooled, and made into granules. The size varies depending on the cooling rate and temperature, and has a range of 0.1 cm to 1 cm. The black and blue colors of the cloisonne pigment are produced at a high temperature and the size of the particles is small. Cyan and yellow are made at medium temperature and the particle size is medium. Red, blue and peach color are produced at low temperature. . In addition, the color of the cloisonne pigment varies depending on the baking temperature, the number of times it enters the kiln, and the type of the base plate.

On the other hand, the first cloisonob pigment is composed of a glaze and a first oxidizing pigment. It is preferable that the first cloisonob pigment is mixed in a ratio of 2 to 5 parts by weight of the first oxidizing pigment to 100 parts by weight of the glaze.

The glaze of the first cloisonob pigment is composed of a combination of at least one of silica, graphite, potassium nitrate, soda powder, boric acid, nephrite, arsenic, and antimony oxide. The first oxide pigment is selected from the group consisting of copper oxide, cobalt oxide, Iron oxide, chromium oxide, manganese oxide, and manganese dioxide.

The glaze contained in the first cloisonob pigment is classified into a transparent glaze and an opaque glaze.

In the case of a transparent glaze, it is more preferable that the composition is formed in a chemical composition ratio as shown in <Table 2> below.

<Table 2>

Further, in the case of the opaque glaze, it is more preferable to form the composition in the chemical composition ratio as shown in <Table 3> below.

<Table 3>

On the other hand, when the cloisoner 30 to be decorated in the cloisonne decoration section 20 is to be decorated with a blue-based color, it is preferable to mix the glaze contained in the first cloisone pigment with copper oxide or cobalt oxide. In addition, when the glaze and chromium oxide are mixed, the cloisonne (30) emits a green-based color. When the glaze and the oxidizer iron are mixed, the cloisonne (30) emits a brownish color. When the glaze and the manganese oxide chrome are mixed, (30) emits a black-based color, and when mixed with glaze and manganese dioxide, it emits a purple-based color.

Subsequently, the ceramic body 10 in which the first cloisono pigment is drawn is fired at a temperature in the range of 850 ° C to 950 ° C (S60). The first cloisonna pigment has a characteristic of being melted within a range of 850 캜 to 950 캜.

The first cloisonnote pigment is adhered to the surface of the cloisonne ornamental part 20 of the ceramic body 10 by firing the pottery body 10 with the first cloisonne pigment in the range of 850 캜 to 950 캜 So that the cloisonna 30 of the cloisonné decoration unit 20 composed of the first cloisonné pigment is not peeled off from the body 10 of the pottery. Here, if the cloisonné decoration unit 20 is used, the glaze component of the ceramics 1 melts before the first cloisone pigment is melted, so that the first cloisone pigment does not stably settle, The cloisonne bulb 30 of the cloisonné decoration unit 20 composed of the cloisonne pigment 1 is easily peeled off from the ceramics body 10.

Subsequently, a second cloisonel pigment having a melting point lower than that of the first cloisone pigment is formed in the remaining region of the cloisonné decoration section 20 of the ceramic body 10 (S70). When designing with the second cloisonne pigment, various colors can be connected naturally by the Bokashi technique which makes the boundary of color and color fade, and it becomes possible to express more stereoscopic and beautiful color.

The second cilobo pigment comprises a glaze and a second oxidizing pigment. The second cloisono pigment is preferably blended at a ratio of 2 to 5 parts by weight of the second oxidizing pigment to 100 parts by weight of the glaze.

On the other hand, the glaze of the second cloisonob pigment is composed of at least one of a combination of silica, podium, potassium nitrate, soda powder, boric acid, nephrite, arsenic and antimony oxide. Or a combination thereof.

In particular, the glaze contained in the second cloisono pigment is classified into a transparent glaze and a non-transparent glaze.

In the case of a transparent glaze, it is more preferable that the glaze is formed in a chemical composition ratio as shown in <Table 2>.

Further, in the case of the opaque glaze, it is more preferable that the composition is formed with the chemical composition ratio as shown in the above-mentioned <Table 3>.

On the other hand, when it is desired to decorate the cloisonné (30) decorated in the cloisonne decoration part (20) with a red-based color, it is preferable to mix the glaze and gold contained in the second cloisone pigment. In addition, when the glaze and cadmium oxide are mixed, the cloisonne (30) emits a reddish color, and when the glaze and silver oxide are mixed, the cloisonne (30) emits a yellowish color.

Subsequently, the ceramics body 10 in which the second cilio pigment is drawn is fired in the range of 780 ° C to 830 ° C (S80). The second cloisonna pigment has a characteristic of being melted in the range of 780 ° C to 830 ° C.

Thus, the second cloisono pigment is fired on the remaining surface of the cloisonne decoration section 20 of the ceramic body 10 by firing the ceramic body 10 having the second cloisono pigment in the range of 780 ° C. to 830 ° C. The cloisonné 30 of the cloisonné decoration unit 20 made of the second cloisonné pigment is not peeled off from the body 10 of the pottery. Particularly, since the second cloisono pigment designed in the cloisonne decoration unit 20 is fired at a temperature lower than the melting point of the first cloisone pigment, the cloisonne decoration area designed with the first cloisone pigment is not melted, 1 without being easily peeled off from the surface of the ceramic body 10.

On the other hand, when the cloisonné decoration unit 20 is used as a glaze component of the ceramics 1 and then the first cloisono pigment and the second cloisono pigment are designed, the glaze component of the ceramics 1 becomes the first cloisonob pigment The first cloisono pigment and the second cloisono pigment do not stably settle on the cloisonne decoration section 20 because they are melted before the second cloisonne pigment. As a result, the cloisonobo 30 of the cloisonné decoration unit 20 composed of the first cloisonob pigment and the second cloisonl pigment easily peels off the ceramics body 10, resulting in defective products.

Therefore, the method of manufacturing a ceramics according to an embodiment of the present invention is characterized by designing the first cloisono pigment and the second cloisono pigment in a state where the glaze of the ceramics 1 is not applied to the cloisonne decoration unit 20 .

The method of manufacturing a ceramic according to an embodiment of the present invention is characterized in that the cloisone pigment is painted and fired twice over several times without separately drawing and firing the cloisone pigment according to the melting point of the cloisone pigment.

When the ceramic kiln is opened at a high temperature due to the nature of the ceramic kiln, the cool air rapidly reaches the surface of the ceramic (1), and the ceramic body (10) The production cost is increased because it is required to be fired for a long time. Accordingly, the present invention is based on the results of a number of experiments, in which the cloisonne pigment having a similar melting point temperature is divided into a first cloisono pigment and a second cloisono pigment, and the cloisonne decoration unit 20 is designed and fired to minimize the number of firing . As a result, the manufacturing process can be simplified, mass production is possible, and the manufacturing cost can be reduced.

On the other hand, when the pottery body 10 is additionally painted with gold, the porcelain body 10 having the second cilobo pigment is fired, for example, after the firing of the pottery body 10 having the cilio- And gold is applied to one area of the ceramic body 10 (S90).

Then, the ceramics body 10 painted with gold is fired in the range of 780 ° C to 800 ° C (S100). On the other hand, the reason why the ceramics body 10 painted with gold is fired in the range of 780 ° C to 800 ° C is that since each cedar-base pigment is water-based, due to the nature of gold, . Therefore, the ceramics body 10 painted with gold is fired singly without being fired together with the cloisonna pigment.

As shown in Fig. 3, after the ceramics body 10 having the second cloisonnal pigment is fired, it is possible to obtain a bag-like ornamental article, for example, ceramics 1, do.

As described above, according to the present invention, after the ceramics body is preliminarily fired in the range of 1260 ° C. to 1300 ° C., the ceramics having a high melting point in a cloisonne pigment to which a ceramics glaze is not applied, So that the manufacturing process can be simplified, mass production is possible, manufacturing cost can be reduced, and occurrence of defective products can be reduced.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
