Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a glazed earthenware having air permeability and a method for manufacturing the same,

The present invention relates to a method of manufacturing a glazed earthenware having air permeability and a pottery manufactured by the method, and more particularly, to a pottery of Onggi with a breathable function and a fine loess soil, The present invention relates to a method for manufacturing a glazed earthenware having air permeability by mixing well-dried ash-bearing ground flour and a glazed earthenware produced by the method.

In general, ceramics are formed by combining a raw material, a raw material, with a raw material, then molding the raw material into a kiln, and then performing a preliminary firing, and a glaze is applied to the preliminarily fired state.

Such ceramics are smooth and matte to prevent moisture from penetrating the surface. This is because the glaze is fired on the surface of the pre-fired state, and the glaze has a great influence on the quality of the ceramics, do.

Such a glaze is a thin glass layer adhered to the surface of a ceramics, lowering the absorptivity of the magnet, expressing aesthetic feeling, and imparting a strong strength to the ceramics. That is, the glaze is a preparation used for forming a glossy or matte surface layer on a surface of a ceramic, a pottery or the like, and is heat-treated and fused to increase the aesthetic effect and strengthen the pottery .

The glaze which is painted on the surface of ceramics and made glossy by firing is generally composed of feldspar, zircon, limestone, ornithine, talc, fluorite, bone powder and carboxymethyl cellulose as main components and a small amount of pigment added thereto.

Among these components, the lead name or the lead oxide obtained by heating lead oxide to 40 to 45 ° C or more is not only a pollutant harmful to the human body but also pollutes the working environment in the course of the firing process, Is known as a toxic substance. In addition, there are few labor costs and time-consuming price competitiveness besides the burden of having to bake second chaebol.

However, since the light is suitable as a fusing agent in the formation of glaze, it is necessary for the user to know the toxicity thereof.

In addition, conventional glaze for ceramics was easily used for coloring ceramics by mixing a separate pigment, but it was limited in that it could not save the luxurious and delicate Korean natural beauty like the celadon and white porcelain in the past in China or the Koryo dynasty.

Domestic registered patent No. 0831251

Accordingly, it is an object of the present invention to solve the problems of the conventional glaze containing a separate pigment such as a harmful substance such as a bright name and a ceramics during production of celadon, white porcelain and Onggi, And does not cause pollution to the environment and harmless to the human body. The glaze is applied without glazing so as to save the beauty of Korea. It reproduces natural color and aesthetics and emits Korean natural beauty and manufactures beautiful surface earthenware It has its purpose.

In particular, the present invention relates to a method for manufacturing a glazed earthenware having air permeability by mixing ongyo with a breathable function and a fine loess dipped in water into pure ocher soil, The present invention has been made in view of the above problems.

In order to solve such a technical problem,

A first step of aging the aged mortar mixed with 60 to 80 parts by weight of loess, 5 to 9 parts by weight of pine wood, and 2 to 4 parts by weight of pine wood, based on 20 parts by weight of Onggi soil; A second step of joining and drying the earthenware to form the green body and drying it in the shade; And a third step of putting the earthenware into the kiln and firing and cooling the earthenware.

At this time, in the first step, the Onggi soil is pulverized twice or three times using a jet mill, and is filtered through 60 to 100 kinds of wood to be used as a material. The yellow soil is collected as red , And it is filtered using 60 ~ 100 kinds of woods and used as the material of the fine loess that has settled down. The above-mentioned sacred land material is dried at 60-100 neck And the pine wood is melted in water to make lye, and the pine wood is filtered with about 60 to 100 kinds of wood, and the precipitated pine lye is used as a material.

The second step is a step of performing a complete drying in which the earthenware is formed in the form of a holy thing or a living bowl, and is dried after the primary drying and removing the moisture.

In the third step, the earthenware is placed in a kiln, and the mixture is reduced and calcined in a temperature range of 1100 to 1200 ° C., followed by cooling the kiln for 2 to 3 days.

The present invention also provides the earthenware produced by the above method.

The method of manufacturing a glazed earthenware pot with air permeability according to the present invention and the earthenware manufactured by the method are different from the pottery products containing chemicals such as ceramics which are harmful to the human body and which are expensive and have been baked with glazed kaolin and glaze Not only does it reduce the cost of manufacturing earthenware by producing earthenware with materials obtained from natural materials that are completely harmless to human body without causing environmental pollution such as air, water quality, soil, etc., There is no proof and it is baked in a kiln with a temperature higher than that of Silla pottery.

Particularly, the present invention has a great significance in producing holy things by using sacred saints having important meaning in the Catholic faith at the time of manufacturing the earthenware, Not only can reduce environmental pollution, but also glaze is not applied to the inner and outer surfaces of the earthenware to ensure ventilation, and it is advantageous to maintain freshness for a long time when used as a jar and a living bowl which can store rice and various foods.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flow chart for manufacturing a glazed pottery having breathability according to the present invention. FIG. According to this, the airless glazed earthenware pots are made of Onggi soil, which has the function of breathing, and the fine loess, which picks up our pure ocher soil and drains the soil, The saffron material is finely grinded by using a mortar mill and finely dried. The saffron material is mixed with a certain ratio of materials such as onion soil, loess soil, and sacred material. .

The raw materials of the earthenware use only the material obtained by collecting natural materials which are harmless to the human body, so that they do not cause environmental pollution such as air, water quality and soil, and are harmless to the human body.

Of course, at the time of manufacturing the earthenware according to the present invention, it is possible to mix the pongee materials with the Onggi soil, the loess soil, the sacred pine trees (for example, Dough and stamina.

In this case, the above-mentioned sacred branches (for example, unshiu wood, spruce tree, etc.) and pine wood not only form pores in the production of earthenware but also function as natural pigments that beautifully express the color of earthenware.

Hereinafter, the production method according to the present invention will be described in detail.

(A) Step: Material preparation process

The materials used in the production of the earthenware of the present invention include onggitto, loess, sardine (e.g.

First, onggi soil is generally used as soil for making pottery, adding viscosity and imparting a good blend with other materials. It is desirable to use the soil that has been proven to be the most effective of the Onggi soil to be used in the Onggi soil, and the Onggi soil is a unique unique Onggi soil. In order to make the soil of the present invention, It is crushed 2-3 times using earthenware, and it is filtered after filtering through 60 ~ 100 chest. In this case, it is preferable to remove the impurities in the petroleum process.

The loess is extracted from red loess, and the loess is firstly extracted into water, and the loess is firstly filtered using 60 ~ 100 kinds of poles. The loess dirt that passed through the stalks is a little over time and the loess is submerged and the upper side becomes clear water. Here, clear water is removed and the remaining loess loess is used as a material.

In the present invention, the earth as it is collected from the gravel soil is screened and used. The eastern loess most commonly received in the eastern sunshine is the loess of the loess, which is famous for its eastern loess, and 46.3% of the total area of Gochang-gun occupies 46.3% of the total area.

Hwangto consists of various mineral particles such as quartz, feldspar, mica, and calcite, and it has a characteristic of changing into clay when water is added. Hwangto contains a large amount of calcium carbonate (CACO ₃ ) In general, the metal oxides are composed of 35 to 45% of SIO ₂ , 20 to 35% of AL ₂ O ₃ , 5 to 15% of Fe ₂ O ₃ , 2 to 3% of MgO, 2 to 3% of K ₂ O, Na ₂ O: 1 to 2%, and Ge: 1 to 2%. Co., flatulence when ocher is compared to each ingredient content about the Korea Testing by the SIO _2, the main component of ocher by the component analysis of flatulence ocher AL2O commissioned a researcher _3, Fe ₂ O ₃ and other areas ocher flatulence Loess SIO ₂ The content is much higher than other localities. This means that Gochang Roe emits more far infrared energy absorbed by the human body than the other loess soil, which means that there is much far-infrared radiation energy absorbed by the human body. This is because the loess is composed of a honeycomb-shaped multi-layered structure. The larger the SIO ₂ content is, the more the honeycomb structure. The honeycomb structure absorbs and stores far infrared rays in the air. It acts as the energy of the new core and lightens the body.

On the other hand, the above-mentioned sacred trunks are burnt woods and shrubs which are dried by drying well (for example, one year of drying). Generally, in every church in Korea, in order to prepare Lent Lent in Lent. (February to March), there is a ceremony where the priest builds a sacred branch in the Catholic Church during the annual event on the Sunday before the resurrection of Jesus last year. We have a ceremony to draw the ashes on the forehead of Lent this Wednesday, giving them back to the believer families, taking the duty of hanging them together behind the cross of Jesus, and bringing back the sacred boughs that have been dried for about a year during the Lent , And then use the sacred branches that have been brought to the cathedral from each family to be used for the occasion. At this time, a small amount is used for the ceremony, and the remaining abandoned ash is purchased from the cathedral of the whole country, and it is filtered after 60 ~ 100 trees.

At this time, the sacred pine tree or plain wood is used.

Leaves and fruit are used as medicinal materials in Oriental herbaceous plants. Leaves of bamboo leaves stop bleeding and cool the heat of hot blood. Therefore, it is used for hematemesis, nosebleeds, hemorrhage, and anemia, and is used alone or in skin diseases and mumps. Seabird seeds stabilize the mind, which is effective for insomnia, nervous breakdown, heart beating, constipation and physical weakness, and strengthens sexual function. The leaves of the perennials contain about 1% essential oil, 1.72% of flavonoids, and contain tannins and resins. Cranberry extract has the effect of eliminating sputum and calming the cough. The effect of relaxing the bronchial smooth muscle of experimental rats was proved. Injecting 250 mg / kg of flavonoid contained in the leaves into the abdominal cavity showed a clear cough suppression effect. When the amount is increased up to 1000 mg / kg, . It also has the effect of expanding the blood vessels of the rabbit ears and lowering blood pressure. Extracting the leaves of Alabaster tree with alcohol also shows inhibitory action against Mycobacterium tuberculosis, Pneumococcus, and Qatar. In addition, we can cure acute chronic bacterial dysentery, and can treat chronic bronchitis. We observed 64 patients with pulmonary tuberculosis for more than one month, 38 patients were improved, 12 were unchanged, The case was about 5 days and had a considerable effect. There are also clinical reports that it is effective against pertussis and gastroduodenal ulcers.

It is an effect that promotes blood circulation and metabolism because phytoncide is home to the unicorn tree. Cottonwood contains phytoncide more than five times that of ordinary wood. The antimicrobial activity of phytoncide contained in large amount helps various circulation of the respiratory, atopic, sick house syndrome and stress relieving head to help the sleeping.

The pine wood is an optional material. It is prepared by burning the pine tree to prepare the ash, and the pine wood is poured into water to make lye. The pine wood is cured in water for 2 ~ 3 days to remove the alkali, It filters out. After a certain period of time, the pine material is settled downward and the upper part becomes clear water. At this time, the clear water is discarded and the remaining pine lye is used as a material.

(B) Step: Material mixing and aging process

The prepared materials are mixed, for example, in a mixing ratio of 20% by weight of ongogi, 70% by weight of loess, 7% by weight of sardine, and 3% by weight of pine wood.

When the mixing ratio of each material for the production of the above-mentioned raw materials is converted into parts by weight, 60 to 80 parts by weight of loess, 5 to 9 parts by weight of pine wood, and 2 to 4 parts by weight of pine wood are used relative to 20 parts by weight of Onggi soil . Water can be added to the soil at various weight ratios (water: water = 1: 1 ~ 1: 1.5) depending on the type of earthenware produced when mixing the materials. It is aged 5 ~ 7 days in the aging room to increase the viscosity.

(C) Step: Molding and drying process

Through various works such as manual work, spinning work, and molding works using gypsum mold, it is possible to use the form of statue, crucifix, jasmine statue, Joseph adult statue, Jamo statue, water bottle, It carries out the shaping of earthenware molding, bending or shaping. Then slowly dry in a shady or cool place.

In this case, the primary drying process is performed in which the water is removed from the earthenware with the earthenware and the shape of the product is fixed. In this case, the direction is changed so that the sunlight does not rise and the wind is not blown in the shade, Slowly (trim) it dries once again better. After that, the earthenware is subjected to a drying process such as smoothing and shaving, a drying process in which the drying process is completed after sufficient time to dry thoroughly and to remove moisture. When the earthenware is completely dried, it is preferably carried out in the shade for 3 to 5 days.

(D) Step: Firing Step

The earthenware material completed in the step (C) performs a jar preparation work for accumulating the material in the kiln. It takes a lot of labor and cost to bake the earthenware, so fill it with the maximum amount at once and ignite. It is most important to check that there is no gap inside and work after perfect repair. In this way, the earthenware is filled into the kiln, the kiln inlet is sealed with the loess, and the fire is burned.

That is, the baking process is a process of determining the strength and color of the dried earthenware and baking it out of the kiln so that a certain product is produced. The fire is about 24 hours. The burning work to grind the molding from the kiln is fired. At this time, the sintering process is divided into four stages of burning fire, medium fire, big fire, First, warm the inside of the kiln for about eight hours, and when the humidity in the kiln dries up by the heat of the burning fire, it gradually raises the temperature and raises it by the medium fire. In mid-fire, soot on the surface is burned and all are dark red. When you begin to plow a large fire that grows a fire in a medium fire, the temperature in the kiln slowly goes up to 850 ° C, and the loess regenerates the atomic arrangement after chemical reaction. At this time, the body of the molding is warmed to near orange color and the entire surface of the kiln is wrapped. When it reaches the highest temperature, it will have a unique color and harden more firmly. When the fire is out, the chimney is closed and cooled slowly so that the molding does not shrink. Failure to control the temperature during this process will result in distortion or cracking of the shape, so care must be taken.

In other words, if the earthenware is placed in a traditional kiln (kiln) or a gas kiln, and then the earthenware is calcined at a temperature in the range of 1100 to 1200 ° C to complete the earthenware, the earthenware As the surface of the glaze has been applied, beautiful and beautiful earthenware products are completed with natural natural beauty.

(E) Step: Ejecting process

When the firing of the earthenware is completed through the step (D), the earthenware is cooled by cooling the pot for 2 ~ 3 days without taking out the earthenware directly from the kiln. When the cooling of the kiln is completed, the entrance of the kiln is closed and the finished earthenware is taken out. Carry the finished earthenware by hand.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
