The present invention is capable of various modifications and various embodiments and is intended to illustrate and describe the specific embodiments in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present invention, terms such as comprise, having, or the like are intended to designate the presence of stated features, integers, steps, operations, elements, parts or combinations thereof, and may include one or more other features, , But do not preclude the presence or addition of one or more other features, elements, components, components, or combinations thereof.
The present invention provides a celadon glaze composition comprising loess, elvan, and a solvent.
The loess is known to have antifungal, far-infrared and anion releasing action, physiological activating action and the like.
It is also preferred that the loess is also ground and added as a powder. Specifically, the loess may be a fine powder having a particle diameter of 1000 to 1500 mesh, more preferably 1200 to 1500 mesh. When the diameter of the loess is less than 1500 mesh, the antibacterial ability of the loess decreases. When the loess exceeds 1000 mesh, stirring with other granite powder may not be smooth.
Quartz Porphyry is a grayish white colored Ansan porphyry, which is named after the stone is like a barley grain. Component of quartz porphyry is Ge (germanium), SiO 2, Al 2 O 3, Fe 2 O 3, CaO, MgO, K 2 O, NaO, TiO 2, P 2 O 5, MnO, TiO 2, P 2 O 5, MnO, etc., and its use is expanding because it is rich in minerals and minerals beneficial to the human body. Strong adsorption, precipitation of minerals, control of water quality, and control of dissolved oxygen in water have been reported. Elvanite is a porous material with many pores and adsorbs through the pores to remove impurities in the solution, remove heavy metals, and capture cells, and exhibits mineral leaching, anion elution promotion effect, and far infrared ray generation effect.
The elvan is preferably pulverized and added as a powder. Specifically, the elvan stone may have a particle diameter of 100 to 500 mesh, more preferably 200 to 400 mesh. When the elvine stone is contained in the celadon glaze composition as powder within the above range, the far-infrared ray generating effect and the heavy metal catching effect are improved.
If the granite powder has a particle size of less than 500 mesh 탆, the effect of generating far infrared rays of the elvan stone may be deteriorated. If it exceeds 100 mesh, precipitation may occur after mixing the glaze, .
It is preferable that the fine clay and the elvan powder have an average particle size in the above range in consideration of the curing characteristics of the celadon glaze composition, the gloss of the celadon oil, smoothness, surface roughness and the like. The loess is pulverized into fine powder, and the loess powder and the elbow stone powder are mixed with different particle sizes to improve the durability by fixing the loess fine powder to the porous compact stone.
The loess and the elvan stone may be obtained by drying the loess and the elvan stone by hot air at 50 to 100 DEG C for 2 to 4 hours and then pulverizing the dried loess and the elvan to a particle diameter of 100 mesh or less, The ground loess and the elvan stone are respectively immersed in purified water to selectively flocculate loess and pulverized fine grains, and the dried loess and pulverized fine grains are secondly pulverized within the above range. Since a fine powder floating after dipping in purified water is used, a light and fine powder can be used.
And the mixture of the loess and the elbow is pulverized into the above range to prepare the loess-elvan mixture.
The above-mentioned loess-elvan mixture may be immersed in purified water and aged for use. When the above-mentioned aging step is carried out, it is preferable to aged at least 3 days at a low temperature of 0 to 4 ° C. It is possible to improve the dispersibility of the loess and argillaceous stones by aging the loess-elvan mixture, and to improve the far-infrared ray generation and the anion emission effect.
The loess and the elvan may be contained in a weight ratio of 1: 2 to 1: 4. If the amount of elvanite is less than 2 parts by weight based on 1 part by weight of the loess, the color of the celadon can be altered. If the amount of elvanite is more than 4 parts by weight based on 1 part by weight of the yellow clay,
When the loess and the elvan are mixed at the weight ratio within the above range, the durability is improved and the celadon applicable to the microwave oven can be manufactured, and the fixing of the loess and the elvan powder having different grains can be suitably performed.
The loess and elvan are added to the celadon glaze composition, which is stable, improves the smoothness of the oil surface, improves the surface roughness, and increases the strength.
In the preparation of the celadon glaze composition, it is preferable that the loess and the elvan are mixed and used first.
The solvent may be isopropyl alcohol (IPA), ethanol, distilled water, or the like.
The celadon glaze composition comprises 200 to 400 parts by weight of elvan, 200 to 300 parts by weight of feldspar, 80 to 90 parts by weight of limestone, 200 to 300 parts by weight of limestone and 50 to 70 parts by weight of clay with respect to 100 parts by weight of loess .
The feldspar, the silica and the limestone are the three major ingredients of the glaze and the glaze. The feldspar is added to the clay to dissolve the clay or the quartzite to serve as a flux, which helps to melt the clay and limestone and help the glaze to fuse on the clay face. The feldspar is an aluminum silicate mineral containing potassium, sodium, calcium, and barium and is represented by the formula (K, Na, Ca, Ba) (Al, Si) 4 O 8 .
The silica is mainly composed of glass and serves as a framework of glaze. Since the silica itself is melted only in glass or high temperature, it is combined with low-temperature feldspar or limestone to produce a glaze at a proper temperature. Increasing the silica in the glaze increases the melting temperature (also increases the fire resistance), increases the hardness and strength, and reduces the expansion coefficient.
The limestone is a kind of limestone, and it is a kind of abundant calcium, and it is added to the glaze, so that the surface of the glaze is smooth and even, and it emulsifies. The limestone is mostly used as a raw material for glaze and the powder state is slightly grayish white and affects the gloss and flexibility of the surface of the ceramics in addition to the above functions.
If the skeleton of the glaze is formed by the three elements of the glaze, that is, feldspar, silica, and limestone, it is possible to add a coloring agent such as oxide separately or add a colorant or a crystallizer to adjust the transparency or surface state of the glaze have.
The feldspar, the silica and the limestone may be added to ordinary glazes, but are not limited thereto.
The above clay is a white to light gray green kaolin clay containing a large amount of quartz grains having a diameter of about 1 to 3 mm in a scattered point shape and is used in a small amount in a glaze to prevent the glaze from sinking on the floor.
A technical method for achieving the above object provides a method for preparing a celadon glaze composition.
The celadon glaze composition comprises a step of separately crushing loess and elvan, a step of selectively filtering the yellow loam and elvan fractions floating in the solvent by immersing the loess and the quartz in a solvent, mixing the loess and pulverulent minerals to form an ocher- , Wet mixing the feldspar, zircon, limestone, and clay clays in powder form with a solvent to produce a wet mixture, and stirring the wet mixture with the mixed loess-elvin stone mixture.
The step of blending the celadon glaze composition may further comprise immersing the loess-elvin stone mixture in purified water before agitation with the slurry mixture and aging.
The stirring and mixing methods may be performed in various manners. Specifically, the loess-elvan mixture may be prepared by dry stirring in an agitator.
The wet mix preparation step may be a wet ball milling process. The ball milling process will be described below. Powdered feldspar, quartz, limestone, and persimmon are each put into a ball milling machine and wet-mixed with the solvent. The material is mechanically mixed by rotating it at a constant speed using a ball milling machine. In order to suppress the generation of impurities, the balls used for the ball milling preferably use ceramic balls such as alumina and zirconia. The balls may be of the same size or may be used together with balls having two or more sizes. It is possible. The size of the ball, the milling time, and the rotation speed per minute of the ball miller. For example, the size of the ball may be set in the range of about 1 to 50 mm, and the rotational speed of the ball miller may be set in the range of about 50 to 500 rpm. The ball milling is preferably performed for 1 to 48 hours. The wet mixture is mixed by ball milling and has a uniform particle size distribution. When the wet mixing process is performed as described above, the material is undifferentiated to form a slurry state, and such a slurry material can be used as a celadon glaze composition composition.
By mixing and stirring the loess-elvan mixture and the wet mixture, respectively, the effect of the loess-elvan mixture can be maximized.
Alternatively, a method of dry-glazing the glaze by using a mixture of a loess-elvan mixture (dry) and a wet mixture, instead of a conventional gel-type glaze, may be used.
Hereinafter, a method for producing celadon celadon using the celadon glaze composition will be described.
The celadon manufacturing methods are (1) selection of the body, water, stool, and molding (blue goods manufacturing), (2). 1st firing, (3). (4). Secondary firing, 5. spawning and screening.
The above-mentioned firing is an important process in the ceramics work, which refers to the making of earthenware vessels, porcelain vessels and ceramics by burning. 9 to 11 hours to 800 ~ 900 ℃ for 14 ~ 16 hours (950 reduction) to 1230 ~ 1300 ℃ for secondary firing (chrysery roasting) to show the color of celadon according to glaze. .
To prepare the celadon, prepare the soil (胎 土). The attic can be prepared according to a conventional celadon manufacturing method. The attitu is formed into a desired shape to form a blue luminescent material. The term "celadon" is used to mean a celadonite formed to produce a desired type of celadon. The molding can be carried out by various known methods such as injection molding, extrusion molding, and the like.
The above-mentioned formed blue-violet object is firstly fired. It is desirable to open the damper of the kiln door and the chimney up to 200 ° C in order to discharge water vapor from the gas kiln and firing for 9 to 11 hours slowly until the temperature reaches 800 to 900 ° C . The adsorption water in the material is completely evaporated between 180 ~ 200 ℃ when the damper of the kiln door and the chimney is opened and the chemically crystal water chemically bonded to the atmosphere between 510 ~ 710 ℃ and the gas contained in the organic material evaporate . In the first firing process, the temperature is gradually increased because the attic is shrunk and weakened considerably. It is important that the release of water vapor and gas increases the likelihood of cracks on the outer surface of the ceramics.
The celadon glaze composition is applied to the primary fired blue celadon. Suyu refers to the process of glazing the first fired pottery. The glaze forms a vitreous membrane on the surface of the celadon body where the micropores exist, inducing the strength enhancement and the absorption reduction, and exhibiting the inherent color and texture. In the first state, the glaze that is released into water is absorbed together with the water to make glaze on the surface. However, too rapid absorption may cause pores, which may increase the number of pinholes. In order to reduce the number of pinholes or prevent excessive absorption of glaze, the surface of the object can be wiped with a wet sponge or immersed in water for a moment. For example, the method may be carried out in various ways, for example, by immersing the first fired blue celadon in a celadon glaze composition prepared according to the above method, applying the celadon glaze composition to the surface of the celadon with a brush or the like, And a method of spraying the glaze composition onto the surface of the blue crayfish with a spraying device. In addition, it can be used by various methods such as dipping method, squeezing method, spraying method, painting method, vibration method, volume method, volatilization method and the like.
If you do not take the unglazed goods out of the kiln immediately, you should be careful not to get rid of the glaze if you keep touching the objects with dirty or sweaty greasy hands. Syringes should also be of adequate thickness.
Most of the above-mentioned souring methods are wet-type sourcing, or dry sour glaze is used to double-sour only the part where functions are required.
The celadon celadon can be manufactured by second firing at a temperature of 1230 to 1300 ° C. The secondary firing is gradually heated from low temperature until it reaches 700 ° C, and when the inside of the kiln reaches 700 ° C, the inside of the kiln becomes dark red, and all fire holes for glaze are closed and the temperature is rapidly raised to 1230 to 1300 ° C . From 900 ° C, the color of the glaze changes significantly depending on the firing atmosphere. The present invention is characterized in that it is baked in a reducing salt. Reduced salt burns less fuel when oxygen is lacking, and less carbon fuel requires oxygen, so it takes oxygen contained in glaze or tattoo and burns it. Minerals that have been associated with oxygen in glazes or fissures will give off oxygen and return to their original state. Since the minerals that released the oxygen are reduced to their original state, the copper becomes the original red, and the iron becomes the blue. In the second firing, the stones become glassy, and the glaze components melted and become glassy.
If the secondary firing temperature is lower than 1230 ° C, the celadon glaze composition may be incompletely melted, the surface of the celadonite may not be smooth or the gloss (shine) characteristics may be poor. If the temperature is higher than 1300 ° C, There can be a lot of non-economic. Further, it is preferable that the secondary firing is maintained at the firing temperature for 14 to 16 hours. If the second firing time is too long, it is not economical because it consumes a lot of energy, it is difficult to expect further firing effect, and if second firing time is small, incomplete firing can be achieved. The firing is preferably performed in a reducing atmosphere (for example, a liquefied petroleum gas (LPG) atmosphere or a liquefied petroleum gas (LPG) atmosphere and air mixed atmosphere).
A method for manufacturing a celadon glaze composition containing loess and elvan glaze by means of the solution of the present invention and a celadon produced by the method are not mixed with clay in the earth as a ceramics material, The celadon tableware according to the present invention is in direct contact with the food, and the far infrared ray emission and the anion elution effect of the tableware according to the present invention can be directly transmitted. In addition, durability is improved by the mixture of the loess-elvan mixture, and a celadon tableware which can be used in a microwave oven, an oven, a dishwasher, etc. can be provided.
