Manufacturing process of heat-resistant ceramics coated with different glazes and heat-resistant ceramics using the same {manufacturing process of heat-resistant ceramic applied two kinds of glaze and heat-resistant ceramic using the same}
[9] The present invention relates to a heat-resistant porcelain manufacturing method coated with two kinds of glazes and a heat-resistant porcelain using the same, and more specifically, a heat-resistant porcelain manufacturing method for applying different glazes to all surfaces except the inlet and the inlet and the heat-resistant porcelain manufacturing method It relates to the ceramics produced using.
[10] Heat-resistant ceramics are formed by mixing or kneading inorganic materials, such as clay, acid, and ferrite, either alone or selectively, then putting them in a kiln by coating them with glaze selectively and firing them at high temperatures in the range of 1150 ℃ to 1300 ℃. This refers to a product manufactured to be hard, light and breathable.
[11] Heat-resistant ceramics, unlike ordinary ceramics is a durable against heat to put food inside and boil, and is manufactured so that the bonding structure is deformed and damaged even if repeated heating and cooling.
[12] Heat-resistant pottery is not damaged by direct fire due to its product characteristics, so it is closely used in our real life as a container for boiling food.
[13] Hereinafter, with reference to the accompanying drawings will be described with respect to the conventional heat-resistant ceramics and heat-resistant ceramics manufacturing method.
[14] Figure 1a shows a cross-sectional view of a conventional heat-resistant ceramics.
[15] As shown in FIG. 1A, a conventional heat-resistant pottery is adhered to the base 10 and the inner and outer surfaces of the base 10 formed by mixing alone or mixed with inorganic materials such as clay, acid blue soil, and ferrite, and is waterproof. Consists of a glaze 12 to increase the strength and hardness at the same time.
[16] Glaze 12 gives the surface of the base 10 to give a more beautiful and compelling to enhance the aesthetic decoration effect and at the same time smooth the surface to increase the resistance to water or chemicals.
[17] At this time, in order to fix the glaze 12 to the base 10, after applying the glaze 12 to the base 10 and put it in a kiln to apply a high temperature heat to modify the bonding structure of the glaze 12, If the glaze 12 is applied to the bottom of 10), the glaze 12 is also combined with the shelf plate in the kiln, so to prevent such a phenomenon, the bottom of the base 10 is wiped off the glaze 12 and put in the kiln.
[18] Figure 1b is a flow chart of a conventional heat-resistant ceramics manufacturing method.
[19] After making the material into the desired shape by using the soft soil kneaded with clay or small support material (step 20), the material is put in a kiln and subjected to the first firing step of applying high temperature heat (step 22).
[20] The molding of the base can be molded by various methods such as jiggering, casting, plastic forming by extruding, and pressing.
[21] Primary firing, also called a first bulb, is a firing mainly used in the manufacture of heat-resistant ceramics. This means that the base material is baked at a low temperature of about 800 to 900 ° C. to give the mechanical strength to the body so that the work such as painting or glazing can be easily and safely performed.
[22] At the end of the 1st firing (22 steps), apply glaze to the inner and outer surfaces of the base (24 steps), soaking the base that has undergone the first firing in the glaze to make the surface more beautiful and stand out. After the applied glaze is removed (step 26), the glaze is coated on the base of the glaze so that the glaze is fixed on the surface of the substrate, and then subjected to secondary firing to apply high temperature heat (step 28).
[23] At this time, the temperature of the secondary firing becomes a temperature (about 1,250 ° C.) much higher than the temperature of the primary firing. Through the secondary firing, the base has sufficient mechanical strength, and the glaze applied to the surface of the base is deformed and bonded to the surface of the base.
[24] However, the conventional heat-resistant pottery as described above, because the glaze is not applied to the bottom, not only aesthetically good, but also put the food inside, so that the flame and the base directly contact when heating the bottom soot is generated.
[25] In addition, the base material is made to be capable of expansion and contraction by heat so that it does not break even when heated to a high temperature by directly contacting the flame on the bottom of the base material to which the glaze is not applied. Thus, in order for the body to be able to expand and contract by heat, the body is not fully cooked and hardened, and it is fired so that the body is not fully cooked. Heat-resistant ceramics manufactured in this way have a disadvantage that food is permeated into the body. have.
[26] In addition, the bottom of the heat-resistant porcelain is not coated glaze is exposed directly to the outside of the coarse particles, there is a disadvantage that a scratch occurs when placing the heat-resistant porcelain on a small hardness object, such as a table.
[27] The present invention has been made to solve the above problems, an object of the present invention to provide a heat-resistant ceramics coated with glaze on all the inner and outer surfaces, including the bottom.
[1] Figure 1a shows a cross-sectional view of a conventional heat-resistant ceramics.
[2] Figure 1b is a flow chart of a conventional heat-resistant ceramics manufacturing method.
[3] Figure 2a shows a cross section of the base to be applied to heat-resistant ceramics coated with different glazes according to the present invention.
[4] Figure 2c shows a shape in which a low-degree glaze is applied to the upper surface of the mouth of the base.
[5] Figure 3 shows a flow chart of the manufacturing method of heat-resistant porcelain coated with different glazes according to the present invention.

[28] Heat-resistant ceramics coated with a heterogeneous glaze according to the present invention for achieving the above object is a bowl-shaped substrate made of one or more kinds of inorganic substances mixture, a low-grade glaze applied and fixed on the upper surface of the inlet of the base, It is fired at a temperature lower than that of the glaze and is composed of a high glaze that is applied to and adhered to all surfaces of the substrate except the portion to which the low glaze is applied.
[29] Low glaze can be applied to any kind of glaze that melts at a low temperature above 550 ℃ ~ 1150 ℃, and high glaze can be applied to any kind of glaze that melts at high temperature above 1150 ℃ ~ 1300 ℃. It is possible to apply even.
[30] Unlike conventional heat-resistant ceramics which are not exposed to the outside because the glaze is not applied to the bottom, heat-resistant ceramics coated with different glazes according to the present invention are coated with glaze over the entire surface, so the appearance is not soot and soot does not occur. Since the body is not directly exposed to the outside, there are many conveniences in use.
[31] In addition, the high-glaze glaze applied to the inside of the body because the body is inverted and fired, the adhesion to the body is more secured due to the internal radiant heat, and since the inlet of the body does not move close to the floor, the handle is placed on the outside of the body. Even if formed, the shape deformation of the body due to the sag of the handle does not occur.
[32] When the food is put inside the heat-resistant ceramics and heated, the bottom and the outer wall, which are in direct contact with the flame, are coated with a high-temperature glaze fired at a very high temperature, so that the heat-resistant ceramics are not damaged by the flame.
[33] In addition, according to the present invention, a method of manufacturing a heat-resistant pottery coated with different glazes includes: a first step of making bowl-shaped body using soft soil kneaded with water in a small support material; Step, the third step of applying a high-glaze glaze to the entire inner and outer surface of the body, the fourth step of removing a portion of the high-definition glaze applied to the body, seating the base so that the area where the glaze is removed to touch the floor A fifth step of fixing the high glaze to the surface of the substrate by applying heat above the temperature at which the high glaze is fired, the agent for applying the low glaze to the surface of the body including the portion where the high glaze is not applied; The sixth step consists of a seventh step of applying the heat below the temperature at which the low glaze is fired and below the temperature at which the high glaze is melted to fix the low glaze to the base.
[34] In order to ensure that the shape of the body does not deform even during the firing process so that the mouth of the body touches the floor, the high-strength glaze applied to the body of the body is removed in step 4. Apply glaze.
[35] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[36] Figure 2a shows a cross-section of the base to be applied to heat-resistant ceramics coated with different glazes according to the present invention.
[37] The body to be applied to the present invention is made of a material in which one or more kinds of inorganic materials such as kaolin, acid blue, petrite, clay, and the like are mixed and formed into a concave bowl shape.
[38] The strength of the substrate is increased by firing by applying the heat of 800 ~ 900 ℃ to the substrate formed as shown in Figure 2a.
[39] 2B shows a shape in which a high degree glaze is applied to a base.
[40] After applying high-temperature glaze to the entire outer surface of the body calcined by applying heat, the glaze applied to the upper surface of the base of the body is removed, and as shown in FIG. Add high glaze to the outer surface of the base.
[41] At this time, the high-glaze glaze used is a glaze fired at about 1250 ℃, in order to apply a high temperature heat to the substrate is used to put the body in a kiln generating high temperature heat of 1250 ℃ or more.
[42] In order to prevent the body from sticking to the bottom of the kiln, the applied glaze should be removed from the outside of the body which comes into contact with the bottom of the kiln.
[43] Therefore, when putting the body upright in the kiln as in the conventional heat-resistant ceramics, glaze can not be applied to the bottom of the base, in order to apply a high-definition glaze on the bottom of the base, as shown in Figure 2b upside down the base of the base Do not touch the bottom of the kiln. At this time, the applied glaze is removed from the upper surface of the inlet of the base which is in contact with the bottom surface of the kiln.
[44] Figure 2c shows a shape in which a low-degree glaze is applied to the upper surface of the mouth of the base.
[45] 2b immediately after the base to which the high degree of glaze is fixed is applied, as shown in FIG. 2c, a low degree glaze fired at 550 to 1150 ° C. is applied to the top surface of the mouth of the base to which the glaze is not applied and the low degree glaze is applied. The low glaze is fixed to the substrate by applying heat above the temperature to be fired.
[46] At this time, the heat applied to the substrate to which the low-glaze glaze is applied does not melt so that the high-glaze glaze that is already adhered to the body remains at a temperature below the melting temperature of the high-glaze glaze.
[47] Rough heat-resistant pottery is in a state where the glaze is fixed on all sides until the low-glaze glaze is fixed to the base.
[48] Figure 3 shows a flow chart of the manufacturing method of heat-resistant porcelain coated with different glazes according to the present invention.
[49] After making the bowl-shaped body using the soft soil kneaded with water in the supporting material (step 210), the body is fired by applying heat to the body to increase the strength (step 220), and the high-temperature glaze is fired. It is applied to the inner and outer surfaces of the step (230).
[50] At this time, the high-glaze glaze applied to the body is used glaze fired at about 1250 ℃, and the high-temperature glaze is evenly applied to the inner and outer surfaces of the body by immersing the base in the glaze filled with the high glaze glaze.
[51] When the high degree glaze is applied to the outer surface of the body through step 230, the high degree glaze applied to the upper surface of the base of the body is removed (step 240), and placed in a kiln generating heat above the temperature at which the high degree glaze is fired. Allow the high degree of glaze to adhere to the surface of the substrate (step 250).
[52] When placing high-glaze glazed coated material in the kiln, turn the glass upside down so that the high-glaze glaze does not touch the shelf in the kiln, so that it does not stick to the plate during the firing of the high-glaze glaze.
[53] When the body is heated in an upside down state, the internal temperature of the body rises above the temperature of the body surface due to radiant heat, so that the high-density glaze applied to the body surface of the body is more firmly fixed to the body, Since the inlet of the body is in close contact with the shelf plate, the shape of the body is not deformed.
[54] Therefore, when food is contained in the heat-resistant porcelain, food does not penetrate into the substrate, and the shape of the finished porcelain maintains the same shape as that of the substrate.
[55] When the firing of the high-glaze glaze is completed, apply a low-glaze glaze to the upper surface of the inlet of the base that is not applied to the high-glaze glaze (step 260), the temperature above the temperature at which the low-glaze glaze is fired and below the temperature at which the high-glaze glaze melts. The second glaze is fixed to the substrate by applying the heat of (S270).
[56] The low-glaze glaze used at this time is a glaze fired at about 850 ℃, and the temperature of the heat applied to the firing in step 270 to keep the high-glaze glaze that is already fixed to the base material below the melting temperature, During the firing process, the high-strength glaze must not be deformed.
[57] As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached claim.
[58] In particular, the site for removing the low-level glaze applied to the body is not limited to the inlet of the base can be applied to any site of the base. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
[59] When using heat-resistant ceramics coated with different glazes according to the present invention, the glaze is coated on all the inner and outer surfaces including the bottom surface, so that the appearance is beautiful and soot is not generated. The advantage is that when the heat-resistant ceramic is placed on another object, the surface of the object is not scratched.
[60] In addition, because the inlet of the base is in contact with the floor to be fired upside down, even if the handle is formed on the outside of the base there is an advantage that the shape deformation of the body by the deflection of the handle does not occur.
