Description

METHOD MAKING THE GLAZE FOR TRADITIONAL POTTERY BACKGROUND OF THE INVENTION [0001]

The present invention relates to a method for producing lye, in which the re-powder is evenly dispersed and no additional additives are used to prevent the accumulation of lye, preventing the water from leaking while keeping the surface smooth and breathable, To a method of producing lye for traditional Onggi.

Onggi (甕 器) is a traditional vessel of our nation that developed in a long history, and explains the ash glaze used in Onggi and Onggi as follows.

1. Onggi

Ong (甕, 瓮) is the Korean word for "poison", which is a form of bowl.

Poison has been used since the prehistoric times and has been used as a store to store food or to put a body. In the Three Kingdoms period, it is more importantly used for life, and there are large and small venom lines on the tomb wall of Anak 3 of Goguryeo , Baekje and Silla records that they stored rice, liquor, oil, soy sauce, and salted fish.

Also in the first half of the 12th century, according to the 兢 고려 고려 고려 고려 使 使 使 使 使 使 使 使 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 고려 It is also used for drinking water storage.

In addition, in the early period of the Joseon Dynasty, there were 104 officers in 14 institutions such as Bongsung Temple, and there were two assistants.

Thus, it can be seen that poison has been used from the prehistoric age to the life of our people.

On the other hand, Onggi is not simply a poison in the form of a bowl, but rather a concept that collectively refers to a yellowish brown glazed earthenware bowl. It is a concept of poison, glaze, jar, vinegar bottle,药), and is distinguished from poison as a form.

Onggi, which is covered with yellowish brown glaze, has not been found in the spectators and white porcelain kilns of the 15th and 16th centuries. However, it has been found in the 17th century iron porcelain white porcelain kiln, It seems that the Onggi which was glazed on the surface of the conventional earthenware began to be made according to the new social change.

In the 18th and 19th centuries, these Onggi spread rapidly in people's lives according to the demands of society at the time, and they were used in everyday life. In the late 19th century, you can check on the everyday life of Onggi in a pottery with a kiln painted on the wind speed of Kim Jun -

Since the first half of the 20th century, during the colonial period of the Japanese occupation, Onggi was used, and Kwangmyedang was widely used in the making of Onggi since the 1960s.

Onggi, which has such a long history, has the following characteristics.

- Characteristics of Onggi -

① Air permeability: By heating at a high temperature, crystal water contained in the inner wall of the Onggi is discharged, and air is generated between the outside and the inside of the pot. For this reason, Onggi was recognized as a breathing vessel from ancient times.

② Shelf life: The pores of the pottery wall push out the impurities formed on the inner surface, so that the contents can be stored for a long time without decaying.

③ Fermentability: The most important characteristic of Korean food is fermented food. Fermented food is mostly fermented in Onggi. Dried, candied, and cooked rice are containers made for the purpose of fermentation.

④ Economy: Onggi, firewood, glaze, etc. used in Onggi production can be easily obtained from around us, so Onggi was traded at a cheap price that is not burdensome for ordinary people. Because of this economicity, Onggi has been able to occupy the master place of our life container for a long time.

⑤ Variety of Usage: Onggi is used as a diverse food container such as a jar.

However, Ash glaze ]

The ash glaze is a kind of glaze, called lye.

Soaking is made by soaking the ash in the water to make a glass membrane on the surface of the bowl. The plant material is composed of silicate (SiO2), calcium oxide (CaO), subcomponent, aluminum oxide (Al2O3), potassium oxide (K2O), sodium oxide (Na2O), ferric oxide (Fe2O3 ), Magnesium oxide (MgO), manganese oxide (MnO), etc., so that when the ash is in the water, it becomes a glaze.

Pure fluffing occurs when a high temperature is applied, which causes aggregation, and quartz or feldspar is put into it to prevent aggregation of glaze. This is the invention of the long stone glaze, which is believed to have originated in China's six-dynasty period.

In addition, there is a natural glaze phenomenon in the shirato earthenware, which is a phenomenon of vitrification that occurs when the ash falls off from the kiln or flies from the side of the kiln and flows on either side of the bowl. It is presumed that the phenomenon has become a clue to the use of glaze.

On the other hand, in the case of our nation, the use of persecution is universally used from the Gimhae earthenware pottery, which begins to burn earthenware from the high tide using the kiln before and after the Qing Dynasty, to Silla, Baekje, Gaya, Unification Silla, Has come.

As mentioned above, Onggi is clothed with lye in the traditional way, but from the period after the Japanese colonial rule until recently, it is mainly coated with Koryeongdae (chemical glaze). This is because Onggi using the Kwangmyeongdan is radiant enough to show its face on the surface, and it does not break well and is cheaper than anything else.

However, this bright name is fatal to the human body because it is contained in the glaze component which is harmful to the human body. Moreover, if you burn pottery at temperatures over 1200 ° C, the probability of clogging pottery holes in which the pottery buds breathe is increased, and it is difficult to expect the ventilation of pottery pots.

For this reason, more and more consumers are looking for pottery using lye again.

On the other hand, there is an example in which such lye is prepared by mixing soil and wood material (for example, pine wood) into water. However, since the wood is bulky, lumpy ash occurs when incinerated, It was difficult to produce high quality lye when producing lye using ash. This is because agglomerates are difficult to disperse evenly in water because of their large particle size, which makes it difficult to mix evenly with the soil.

In this case, it is possible to produce lye by crushing wood materials using a tool, or by crushing wood materials using a machine. However, when the ash, the material to be ground or crushed, A phenomenon occurs. In this case, since the ash is in the form of a lump, the ash powder does not disperse evenly when the ash is mixed with water.

Moreover, lye is a phenomenon that occurs when the high temperature is applied, and the larger the ash content, the worse the phenomenon becomes.

In order to prevent the accumulation of lye as described above, quartz or feldspar can be changed as mentioned above. However, since the volume of the ash itself is large, there is a limit to prevent the lye from clumping. In addition, mixing lime with quartz or feldspar changes the properties of lye, making it difficult to produce traditional lye.

In the present invention, it is preferable that the ash comprises the volume ratio of the pine needles 2, the pod 1 and the reeds 1, or the volume ratio of the pine needles 2, the bean pod 1,

In addition, in the present invention, the soil is preferably a soil having a viscosity lower than that of the clay but a fine, smooth and organic mixture, and it is also preferable to use a soil not mixed with yellow soil, sand soil and sand.

Further, in the present invention, it is preferable that water used in the sedimentation and water mixing step is a Rhus verniciflua extract.

The method for producing lye according to the present invention does not require a separate physical process in order to pulverize the ash, and it is not necessary to add a separate additive in order to prevent the accumulation of lye.

In addition, the lye produced by the method of producing lye according to the present invention has good dispersibility and can be applied evenly over the entire pottery when the pottery is used, and the pottery does not sink even when the time for the pottery operation is prolonged.

Further, the lye produced through the lye production method according to the present invention can be eco-friendly and can maximize the advantage of traditional Onggi (for example, breathable Onggi). In addition, when the lye produced according to the present invention is used, it is possible to produce a new colored pot of golden color.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a photograph of a golden pot made according to an embodiment of the present invention.

Hereinafter, a method for producing lye for traditional Onggi according to the present invention will be described.

1. Raw material preparation step

1-1. Preparation of fine raw materials

Dried pine needles, bean pods, sesame seeds, reed and aphids are burned to produce ashes. At this time, the pine needles, bean pods, lobsters, reeds and pine needles are burned in the form of fine powder.

On the other hand, the raw materials can go through the watering process. Defense is the work of putting grains of powder or soil in water and shaking them.

In the present invention, the pine needles, pods, spears, reeds and pine needles are well dried and incinerated, the ash is collected, and the pine is poured into a sufficient amount of water to stir and sieve the sieve. Then, Collected separately for a day or so, the settled particles will go down and separated from the crystal clear. Then, remove the separated supernatant, fill it with a sufficient amount of fresh water again, stir thoroughly, allow to stand for a day, and then remove the supernatant again. Repeating this process several times and then drying the thick lye (refined fine lye) that has settled down on the bottom, in the shade, results in a finely powdered ash-treated ash.

In this way, it is possible to prevent unevenness due to uneven and coarse particles on the surface of pottery painted with lye, and to compensate for defects such as change of color tone due to basic component.

1) Ashes

The remaining powder that remains after the burned object is fully burnt is that the nonvolatile inorganic component contained in most of the same plant material has become a non-combustible residue due to heat-hardening.

2) Reasons for using fine materials

When the ash is mixed with the soil, the ash can be mixed evenly. If the ash is mixed with ash and lye, or the lye is mixed, the mixture can be evenly applied to the pot. In other words, the surface of Onggi can be smooth and fine.

3) Reasons for using pine needles, pods, lumps, reeds, and pine needles as raw materials for manufacturing fine materials

Common woods (eg pine, fir, etc.) are burnt after charcoal-like lumps and are very troublesome to use as a material for lye production. In other words, ordinary wood should be finely pulverized by using a separate tool or by using a machine. However, even in such a case, the problem described in the background art occurs and is not an appropriate solution.

However, pine needles, bean pods, spinning reeds, reeds and pine needles are burned in fine powder form after burning, and these materials are very efficient in producing lye because they do not require a separate powdering step.

4) Determination of the mixing ratio of the desired ash

After mixing the pine leaves, bean pods, sesame seeds, reed, and pine ash in the same ratio as in Table 1 below, lye was made to make pottery, and the mixing ratio was determined by comparing the color and gloss. The mixing ratio is the volume ratio.

pine needles Pod Wake Reed That compare One One One Poor color, poor gloss 2 One One Poor color, poor gloss 3 One One Poor color, poor gloss 4 One One Poor color, poor gloss 5 One One One Poor color, poor gloss 6 One One One Poor color, poor gloss 7 One One One Poor color, poor gloss 8 2 One One Appropriately reflected in yellow and brown Light of traditional pottery, excellent gloss 9 2 One One Appropriately reflected in yellow and brown Light of traditional pottery, excellent gloss

As shown in Table 1, it was confirmed that the best lye was produced in the mixture ratio of pine needle 2, pine cone 1, reed 1, pine needle 2, pod 1, and reed 1.

1-2. Soil preparation stage

Prepare soil with a particle size of about 20 to 0.5 micron, which is less viscous than clay but is a mixture of fine, soft and organic materials. At this time, soil should not contain yellow soil, sand and sand.

1) Soil is less viscous than clay but should be fine and soft

When the viscosity is stronger than the clay, it is difficult to apply evenly when the lye is applied to the pot, and the surface of the pot is rough when the soil is thick. Therefore, in order to uniformly spread the lye on the whole Onggi and make a smooth surface and a fine-colored Onggi, the soil used for producing lye should be fine and soft soil although it is less viscous than clay.

2) Why should not it be mixed with loess, sand and sand?

Sand and sand are coarse and coarse particles. As mentioned above, when lye is applied to pottery, the surface becomes rough and it is difficult to uniformly spray lye on the whole pottery pottery.

In addition, the loess is a particle but it is difficult to color traditional pottery. This is because when the pottery containing the gray ash is painted, the traditional pottery of transparent brown is made. However, it is difficult to produce such traditional pottery by using the yellow pottery.

On the other hand, there are various classification methods of soil classification, but classified into four types according to the size of soil particle size: gravel, sand, silt, and clay. Table 1 shows the size of the particle size according to the soil type. Table 1 shows the size of the particle size of the soil particles.

Pebble More than 20mm (20000㎛) sand 2.0 ~ 0.25mm (2000㎛ ~ 250㎛) rough sand 0.25 ~ 0.05mm (250㎛ ~ 50㎛) Fine sand Mass (fine sand) 0.05 to 0.005 mm (50 탆 to 5 탆) clay 0.005mm (5㎛) or less

[Naver Knowledge Encyclopedia] Kind of soil [- Kind] (Industry Safety Dictionary, 2004.5.10, Book Publication Gold) Classification of soil particles by particle size

Also, the soil may be divided into gravel, sand and mud depending on the size of the particle. At this time, the mud is less than 1 / 16mm. Here, clay is classified more finely as needed, and silt of 1 / 16mm (62.5μm) to 1 / 256mm (4μm) is called clay.

According to the above-mentioned classification of the soil, the sand and the sandy soil (soil mixed with a lot of sand) are large in size and do not meet the criteria of the soil according to the present invention. In addition, the loess is loosely consolidated loose clay with calcium carbonate. It is composed mainly of silt-sized particles and meets the criteria of the soil of the present invention to some extent. However, when used in the lye of the present invention, It is difficult to color.

3) Reasons for using organic soil

a) Organic ( organic matter , organic substance , Organic)

It is a substance mainly composed of organic matter. Organic matter refers to carbon compounds, but does not include simple carbon compounds or metal carbonates.

b) Advantages of organic soil

Soils containing organic matter are beneficial to the human body without any harm, have excellent air permeability, and return to nature at the time of disposal, which is highly valuable in terms of environment. Therefore, pottery made from organic lye made from lye is beneficial to the human body and is very environmentally friendly.

However, in general, containers made of plastic material are not broken and convenient for storing, but when they are heated, environmental hormones are detected, food odor is easy to evacuate, the stain is good and the hygiene is not good.

Containers made from these plastics are divided into two types: semi-transparent polypropylene products, which are composed of carbon and hydrogen, and bisphenol A, which is a chemical material. Bisphenol A is harmful to the human body as defined by the Canadian Federal Ministry of Health. In addition, toxic substances such as cadmium and toluene are used in manufacturing plastic containers, which are more harmful to the human body, and it is difficult to recycle them when they are disposed of, resulting in serious environmental problems.

2. Raw material mixing and aging step

Mix ash and soil to a volume ratio of 1: 2: 1, then pour the mixture into water and knead. At this time, the degree of dough does not flow down like a porridge. In addition, ash and soil can be adjusted within the above-mentioned range in consideration of color and gloss. In many of the ashes, the green color becomes yellowish and in the case of many soils, the green color becomes dark red. The aging period of the mixture is preferably about 10 to 300 days.

1) The reason why the degree of dough is not enough to flow down like porridge

When the soil and the soil are kneaded, if there is too much pores in the water, the air will be filled in the pores. As a result, the ash and the soil will not be mixed evenly. If the pores are too small, the air will be difficult to communicate. It does not respond. In order to prevent such a phenomenon, the degree of the dough is set so that it does not flow down like porridge.

In addition, when the dough is aged, it is very easy to store the dough in the aging place if the degree of dough is not enough to flow down like dough.

2) Reasons for ripening

Ripening is the process of decomposing the molecular structure by itself in a natural state, usually storing the substance at a constant temperature and humidity.

In the present invention, through the aging process, the ash component reacts with the organic matter of the soil and has a unique color and luster, and has excellent dispersibility and coating ability of lye.

3. Batch manufacturing stage

The aged mixture is uniformly sieved with a sieve (300 to 800 mesh), and the sieved mixture is dispersed in water. Then, when the sieved mixture sinks, the water is discarded and the remaining sediments are obtained. Such a process may be repeated 2 to 4 times as needed. This process is often referred to as the watering process.

1) Reasons for evenly mixing the mixture

Since the aged mixture is in the form of a lump, it must be sieved and powdered, and when the lye is done, the sieved mixture is evenly coated on the pot. In other words, the surface of Onggi can be smooth and fine.

2) Reasons why sieved mixture is dispersed in water

The aged mixture may contain incompletely burnt coarse particles contained in the ash, or may contain a basic component. If the sieved mixture is not dispersed in water, it is possible to obtain undesired results such as unevenness on the surface of the lye-painted pottery due to uneven coarse particles and basic components, or change in color tone, So that the problem described above can be solved.

4. Mixture of sediment and water

When the sediments are dispersed in water, a potable lye is produced. At this time, the lye is mixed at a volume ratio of 5 to 4 at a sedimentation time of 5-6.

The lye produced in this way is highly dispersible and can be applied to the entire pottery at a uniform thickness throughout the pottery, and the sediment hardly sinks even when the time of the pottery work is prolonged.

On the other hand, Onggi has a small hole in its place as the water evaporates when it is dried during the manufacturing process. When the lye of the present invention is sown on the pottery pot, the pottery gently wicks the small hole, smoothens the surface of the pottery, prevents the water from leaking while maintaining the air permeability of the pottery, and makes the pottery appear traditional.

In addition, water for dispersing sediments can be used by cooling the hot water extract of Rhus japonicus or the bank pulp (the part remaining after removing the seeds from the fruit, which is usually used for edible purposes) and the hot water extract can be used for cooling. You can make a new color of pottery with traditional gold color and other luxurious gold.

When preparing the hot water extract, the weight ratio of lacquer or bank pulp to water is 1: 1, and when the water is completely boiled based on 10 liters of water, the boiling time is maintained for at least 4 hours. If the amount of water is increased or decreased, The extraction time may be adjusted in proportion to the amount of the extraction time.

In the hot water extract solution, Rhizome Extract was used to mix lignocellulosic material 2, pod 1 and reed 1 in volume ratio to produce lye, which was used to produce Onggi. The results are shown in Fig. In Fig. 3 attached, it can be seen that there is a golden colored Onggi which is distinctly different from the traditional traditional Onggi, which is brownish on the side.
