Description

Ceramic Cloisonne {Ceramic cloisonne}

The present invention relates to porcelain cloisonne, and more particularly, cloisonne of various colors are formed on the surface of the engraved porcelain, and among the engraved surface, metal lines are attached to the cloisonne to form an arbitrary pattern, thereby making the existing metal cloisonne. Unlike soil, as a raw material, it is easy to combine, soft, and free to deform without being constrained by design, reducing costs and applying to tableware. In addition, unlike the traditional cloisonne pottery was flat or limited in pattern, it is possible to express three-dimensional and various patterns with distinct lines to increase the artistic value of the product, and to use the Jeju to make local features to be used as new tourist souvenirs. It is about the ceramics.

Cloisonne literally refers to a craft made from colorful and brilliant colored materials, such as jewels of seven colors.The origin of the cloisonne is Egypt, and through Christianity through Greece and Rome, to Europe and to India. After coming through the Buddhist culture to the East.

Cloisonne is a work of glazing glaze on metal or other materials, drawing patterns or shapes on it, firing it at a temperature of 700 to 800 ° C, and repeating it several times depending on the artist. It refers to a wide range of craft and art activities, up to murals. In Korea, the range of use ranges from trinkets and ceremonial items, which is popular with tourists because it shows a cross section of living culture and history.

Cloisonne consists of the underlying metal (pure gold, pure silver, pure copper or single copper), glazes, or fire. The main components of the glaze are silica (SiO ₂ ), soda ash (Na ₂ CO ₃ ), borax, boric acid, opaque, transparent, and translucent glaze, and the color is metal oxide (gold-red, silver oxide-opaque yellow, copper oxide- Green color) as a raw material. There are more than 20 techniques for cloisonne, such as multicolored cloisonne (over 100 colors), sun chilbo (gold, silver, copper brass), park chilbo (gold, silver, copper foil), and a little chilbo (silver There is).

Cloisonne is excellent in cold and fire resistance, semi-permanent, and beautiful in color. In addition, it is possible to join most other objects, so the range of use is wide and varied, and the pattern has any advantage possible. On the other hand, when using large-scale materials, mold making costs are expensive, so it is difficult to produce them arbitrarily, and it is not only difficult to make the flexibility of lines in the design of cloisonne products, but also suitable for food in the case of copper products. There is no problem.

As a method for solving such a problem, there are a manufacturing method of press-formed patterned cloisonne pottery [Korea Patent Registration No. 20324] and line patterned cloisonne pottery [Korean Utility Model Registration No. 29659]. The cloisonne was formed in the groove between the embossed patterns of, and since the outline of the cloisonne was embossed with porcelain, it was difficult to produce a delicate expression and was mostly flat.

On the other hand, tourism souvenirs are related to the expenses that tourists spend almost essentially during their travels, and thus there is a potential for continuous growth with the growth of the tourism industry. However, tourist souvenirs have a lot of imitations of materials and designs, which makes it difficult to develop unique local products. In addition, similar tourism souvenirs are sold to any tourist spot in the country due to innovations in distribution methods, causing clichés on tourist souvenirs, and the purchasing power for them is lost.

Thus, the present inventors made an effort to solve the drawbacks of the cloisonne product and at the same time to develop a local cloisonne craft that can symbolize tourism Jeju using Jeju. As a result, when ceramic porcelain is manufactured by forming intaglio on the surface of ceramics, applying lacquer glaze, and then attaching a metal wire, unlike conventional metal cloisonne, which has a high cost and is difficult to deform and manufacture, or a planar or limited design cloisonne pottery, The inventors have realized that the cost of raw materials can be reduced and applied to tableware as well as being molded in three dimensions to form a wider cloisonne surface, significantly diversifying the design, and improving the artistry.

Therefore, the porcelain lacquerware according to the present invention has a purpose to provide a porcelain lacquer cloth that can contribute to the tourism industry by promoting purchasing power as a rich history and cultural tourism souvenir.

[Description of Symbols for Main Parts of Drawing]

1: metal wire 2: cloisonne

3: porcelain

The present invention is in the ceramics formed with cloisonne on the surface,

A cloisonne (2) is formed on the surface of the intaglio patterned porcelain (3), and the engraved pattern is characterized by a ceramic cloisonne formed by attaching a metal wire (1) on the cloisonne.

In order to manufacture the present invention, 1) by putting the soil containing sodium silicate in the plaster mold to form an intaglio pattern, and then drying the step after firing; 2) pressing black oil onto the surface of the intaglio pattern and then baking at high temperature at 1250 to 1300 ° C .; And 3) applying a lacquer glaze to the surface of the porcelain including the intaglio pattern, attaching a metal wire to the surface of the intaglio pattern, and then firing at 750 to 800 ° C.

When the present invention is further described in detail by dividing the process based on the manufacturing method as follows.

1) First process

Sodium silicate-containing soil is put into the plaster mold to form an intaglio pattern, and then dried and burned.

At this time, in the gypsum work it is important to make the thickness of the gypsum constant. This is to make the distribution of heat uniformly in the kiln after applying the glaze with uniform thickness of the injected soil. If the thickness is not constant, it is likely to break. In addition, 5 parts by weight of sodium silicate is added to the soil used to mix sodium silicate with respect to 100 parts by weight of soil, which is intended to harden the substance. In the present design, the basalts distributed in Jeju island can be powdered and mixed with the general soil to show regional characteristics.

2) second process

The black oil is pushed onto the intaglio pattern surface and then subjected to high temperature firing at 1250 to 1300 ° C. Here, black oil is a black glaze for high-definition, naturally absorbed by the engraved surface of the porcelain to be cloisonne to give a deep color, making the outline of the pattern more clear.

3) 3rd process

A lacquer glaze is coated on the surface of the porcelain including the intaglio pattern, a metal wire is attached to the intaglio pattern surface, and then calcined at 750 to 800 ° C. The metal wire may be a brass wire, red copper wire, bronze wire, silver wire and the like, and is preferably used with a thickness of 0.6 to 1.5 mm in diameter. In order to attach such a metal wire to a specific part of the surface of the porcelain, when an appropriate amount of carboxy methyl cellulose (CMC) is added to the lacquer glaze and mixed and used, the metal wire can be easily attached. At this time, the CMC is preferably used by mixing in a ratio of 0.01 to 1.0 parts by weight with respect to 100 parts by weight of lacquer. In this way, it is possible to freely attach a line to a three-dimensional pottery shape, so that the design can be diversified. At this time, since the melting point of the transparent glaze and the opaque glaze is not only different, but also slightly different melting point for each color, it is necessary to adjust the appropriate temperature in the firing, and to constantly adjust the rate of temperature rise and fall. If the temperature is out of the above range, there is a risk that it will not smooth or burn, and if the temperature changes suddenly, it will burst. Therefore, the temperature is gradually raised from 600 ° C. to the firing temperature for 5 to 40 minutes, then maintained for 3 to 5 minutes to melt the glaze, and then the temperature is lowered at the same rate as the temperature rising rate.

Ceramic lacquer produced in this way is a three-dimensional cloisonne ornament is fixed smoothly and stably, it is possible to express a flexible and various lines. At the same time, the cloisonne is placed on a clean porcelain table to show off its brilliant colors, and it is very economical in the manufacturing process and raw materials, and thus it can be widely applied to ornaments, interior items, tableware and tourist souvenirs.

Hereinafter, the present invention will be described in more detail based on Examples, but the present invention is not limited to the Examples.

Example

First, after making a plaster mold, 5g of sodium silicate per 100g of clay collected from Jeju Island was mixed and put into the plaster mold to form a negative pattern, and then dried and fired. Then, the black oil was pushed on the surface of the intaglio pattern, and then calcined at 1250 ° C. at high temperature. After the lacquer was coated, brass wire was attached to the intaglio surface, and then fired. At this time, the firing was completed by raising the temperature for 10 minutes from 600 ℃ to 750 ~ 800 ℃ and after 4 minutes to turn off the light and cooled for 8 minutes in a kiln with residual heat.

The cross-section of the ceramic porcelain thus completed is shown in FIG. 2, and FIG. 3 is a three-dimensional view of FIG. 2.

Further, according to the same method as above, harbang (FIG. 4), a candlestick (FIG. 5), and a prop (FIG. 6) were manufactured, and photographs thereof are shown in FIGS. 4 to 6, respectively.

As described above, the ceramic porcelain according to the present invention can be expected to diversify the product because there is no restriction of the pattern by the expression of a flexible line, and can be applied to tableware, so the desire of the consumer who prefers the brilliant colors like the cloisonne. It has the effect of contributing to the tourism industry as it meets the needs of the government and has a historical and cultural disposition.
