Description

Technical Field

[0001] The present invention relates to a method for drawing and firing overglaze pictures in order to improve the clarity of pictures drawn in an overglaze manner on porcelain. Background Art

[0002] Cultural heritage is the product of human cultural activities and is recognized as having cultural value in the fields of archaeology, history, art, science, religion, folklore, lifestyle, etc. Countries around the world are continuously making various efforts to explore and protect their own cultural heritage.

[0003] Among them, porcelain, whose traditional manufacturing method has been passed down to this day, refers to porcelain that is shaped into cups, plates, flowerpots, bowls, etc. using fine clay, then coated with glaze, and then fired to make it smooth.

[0004] Due to the characteristics of the material, this kind of porcelain can be preserved for a long time without special measures, and due to its unique shape and atmosphere, it is still used in various places or has the value as an ornament to this day.

[0005] Generally speaking, in order to show patterns on the surface of porcelain, a method of directly drawing pictures on the surface of porcelain using a brush or a tool similar to a brush can be adopted, or a method of transferring the printed pattern to the surface of porcelain using a transfer paper attached with pigment can be adopted.

[0006] Among them, the ways of drawing pictures on porcelain can be roughly divided into overglaze and underglaze methods.

[0007] The overglaze method is carried out through the following steps: first firing for the first time, then coating with glaze, then drawing pictures on the glaze, and then carrying out the final firing; the underglaze method is carried out through the following steps: first firing for the first time, then drawing pictures on the ware fired for the first time before coating with glaze, then coating with glaze, and then carrying out the final firing.

[0008] Such various methods can be appropriately selected considering the nature of the clay raw material of the porcelain product, the intention of the picture to be shown, pigments, glaze, etc.

[0009] However, the disadvantage of the existing overglaze method is that since the picture is drawn on the glaze after coating with glaze, if the coated glaze has good reactivity with the pigment, the pigment may not be applied to the surface of the ware as intended by the artist and may be distorted (bleeding, erasing, etc.) by the glaze.

[0010] Therefore, a method is needed to solve these problems. Summary of the Invention

[0011] Technical Problem

[0012] The present invention is an invention proposed to solve the problems of the above-mentioned prior art, and its purpose is to provide a method for drawing and firing pictures on glaze, which can improve the clarity of the pictures and obtain better works by using the glaze-on method to draw pictures on porcelain.

[0013] The technical problems of the present invention are not limited to the above technical problems, and those skilled in the art will be able to clearly understand other technical problems not mentioned from the following description.

[0014] Technical solution

[0015] In order to solve the above problems, the glaze-on picture drawing and firing method of the present invention for improving the clarity of the pictures drawn on porcelain includes the following steps: the first firing step of firing for the first time after manufacturing the porcelain product; the second firing step of firing after coating the porcelain product with a matte glaze; the particle removal step for removing the particles of the matte glaze formed on the surface of the porcelain product; the picture drawing step of applying a pigment composition on a drawing tool and drawing a picture on the surface of the porcelain product; and the third firing step of coating the surface of the porcelain product with a glaze and firing after the picture is dried.

[0016] At this time, in order to enable the pigment composition used in the picture drawing step to be properly absorbed and fixed on the porcelain product during firing, the second firing step can be carried out under the temperature conditions of optimal fixation, and the temperature conditions of optimal fixation can be a maximum temperature of 1065 °C to 1075 °C.

[0017] In addition, the second firing step can be carried out under the temperature conditions of optimal fixation so that the supercooling degree of the matte glaze coated on the porcelain reaches 70% to 80% of the maximum supercooled state, at the time when the surface of the porcelain product is formed into a state capable of absorbing and fixing the pigment composition.

[0018] In addition, the particle removal step may include the following steps: a dry particle removal step of removing the particles of the matte glaze formed on the surface of the porcelain product in a dry manner; and a wet particle removal step of removing the particles of the matte glaze formed on the surface of the porcelain product in a wet manner.

[0019] In addition, the dry particle removal step may be to remove the matte glaze formed on the surface of the porcelain product by spraying compressed air on the surface of the porcelain product by using a compressed air spraying tool.

[0020] In addition, the wet particle removal step may be to remove the matte glaze formed on the surface of the porcelain product by wiping the surface of the porcelain product with a water-absorbent cleaning tool impregnated with a cleaning solution.

[0021] In addition, the third firing step may be carried out at a maximum temperature of 1250 °C to 1300 °C after applying the transparent glaze.

[0022] Advantages of the Invention

[0023] To solve the above technical problems, the present invention provides an overglaze painting drawing and firing method for improving the clarity of the drawing on porcelain, which performs two firing steps of firing after applying glaze on the porcelain article, and a particle removal step of removing the particles of the glaze formed on the surface of the porcelain article thereafter. Since the drawing step of drawing the picture on the surface of the porcelain article is carried out after such a particle removal step, it is possible to prevent the phenomenon that the glaze particles adhere to the drawing tool or aggregate together during the drawing process, and has the advantage of being able to express very clear, three-dimensional and vivid pictures compared with the existing methods.

[0024] The effects of the present invention are not limited to the above-mentioned effects, and those skilled in the art will clearly understand other effects not mentioned according to the description of the claims. Description of the Drawings

[0040] In the following, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0041] Figure 1 It is a schematic diagram showing the overall process of the method for drawing and firing an overglaze picture according to the first embodiment of the present invention.

[0042] As Figure 1 shown, the method for drawing and firing an overglaze picture according to an embodiment of the present invention may include a first firing step S100, a second firing step S200, a particle removal step S300, a picture drawing step S400, and a third firing step S500.

[0043] The following description is based on this Figure 1 and, with reference to the remaining drawings, each process will be described in detail.

[0044] The first firing step S100 is a process of the first firing after manufacturing a porcelain article.

[0045] In addition, Figure 2 It is a schematic diagram showing the detailed process of the first firing step S100 of the method for drawing and firing an overglaze picture according to the first embodiment of the present invention.

[0046] As Figure 2 shown, in this embodiment, the first firing step S100 may specifically include: a porcelain article manufacturing step S110 of manufacturing a porcelain article, a semi-drying step S120 of semi-drying the porcelain article at normal temperature (20 °C to 25 °C) once, a foot scraping step S130 of scraping the foot formed at the bottom of the porcelain article, and a complete drying step S140 of completely drying the porcelain article at normal temperature twice.

[0047] The subsequent second firing step S200 is a process of firing after applying a matte glaze to the porcelain.

[0048] In addition, Figure 3 It is a schematic diagram showing the detailed process of the second firing step of the method for drawing and firing an overglaze picture according to the first embodiment of the present invention.

[0049] As Figure 3 shown, the second firing step S200 in this embodiment may specifically include a glazing step S210 of applying a matte glaze and an optimal fixing temperature firing step S220.

[0050] The matte glaze glazing step S210 is a process of applying a glaze having a non-glossy, matte texture.

[0051] The reason for using such a non-glossy matte glaze is that the non-glossy matte glaze is less smooth and has a rough nature compared to the glossy glaze. Therefore, it exhibits more excellent characteristics when drawing a picture in the subsequent picture drawing step S400.

[0052] The optimal firing temperature step S220 is a step of firing under optimal temperature conditions to maximize the fixing property of the pigment so that the pigment can be well fixed on the surface of the porcelain product when drawing a picture in the subsequent picture drawing step S400.

[0053] At this time, the optimal fixing temperature condition for maximizing the fixing property can be that the highest temperature during firing is in the range of 1065 °C to 1075 °C. Regarding this, the following will be described with reference to Figures 4 to 6 description.

[0054] Figures 4 to 6 It is a schematic diagram conceptually showing the states of the porcelain and the picture according to the temperature in the second firing step S200 of the glaze-on picture drawing and firing method according to the first embodiment of the present invention.

[0055] First, as Figure 4 shown, if the highest temperature during the second firing is lower than 1065 °C, the matte glaze 20 coated on the surface of the porcelain 5 cannot be sufficiently liquefied. As a result, the glaze powder 20a adheres to the brush of the picture tool T, and the pigment composition 10 becomes entangled on the matte glaze 200, so that the picture that the writer wants to express may not be able to be expressed.

[0056] On the contrary, as Figure 5 shown, when the highest temperature during the second firing exceeds 1075 °C, the supercooling degree after the liquefaction of the matte glaze 200 develops to the extent of forming a surface coating glassy substance.

[0057] Therefore, in this case, when drawing a picture on the surface of the porcelain 5, the pigment composition 10 cannot penetrate the porcelain product 5 but remains on the surface of the vitrified matte glaze 200. After that, in the case of the subsequent third firing step S500 of coating and firing glaze thereon, the picture may also not be expressed as expected, such as diffusion or erasure.

[0058] The inventor finely adjusted the temperature conditions and conducted hundreds of experiments. As a result, it was found that when the highest temperature of the second firing is 1065 °C to 1075 °C, the pigment composition 10 can penetrate well into the porcelain product 5, and even after the subsequent third firing step S500, the picture can be presented very clearly.

[0059] As Figure 6As shown, when the maximum temperature during the second firing is 1065°C to 1075°C, the degree of undercooling of the matte glaze 200 can proceed to a level where no vitreous substance is formed.

[0060] After the solid powder state formed by mixing the raw materials of the matte glaze 200 is liquefied and then undergoes undercooling treatment, a vitreous substance that smoothly covers the surface of the porcelain can be formed. Here, it is understood that the best state for the pigment composition 10 to be well absorbed and fixed on the porcelain product is when the undercooling proceeds to a level where the vitreous substance is not fully formed and the solid powder does not stick.

[0061] Thus, when the maximum undercooled state is set to 100%, the degree of undercooling at which the vitreous substance is completely formed can be defined as 70% to 80%.

[0062] Next, the particle removal step S300 is a process of removing the matte glaze particles formed on the surface of the porcelain product.

[0063] That is, in this embodiment, after the second firing step S200 is performed and before the subsequent drawing step S400, the particle removal step S300 is carried out. This step is to remove the matte glaze particles on the surface of the porcelain product to an appropriate level so that the pigment composition can be absorbed and fixed on the surface of the porcelain product.

[0064] In addition, Figure 7 FIG. is a schematic diagram showing the detailed process of the particle removal step S300 of the on-glaze drawing and firing method according to the first embodiment of the present invention.

[0065] As Figure 7 shown, the particle removal step S300 in the present invention may include a dry particle removal step S310 of removing the particles of the matte glaze formed on the surface of the porcelain product in a dry manner, and a wet particle removal step S320 of removing the particles of the matte glaze formed on the surface of the porcelain product in a wet manner.

[0066] At this time, the dry particle removal step S310 can remove the matte glaze formed on the surface of the porcelain product by spraying compressed air onto the surface of the porcelain product.

[0067] For example, in the dry particle removal step S310, a compressed air spraying tool, such as an air gun, can be used to spray compressed air onto the surface of the porcelain product to initially remove the particles of the matte glaze formed on the surface of the porcelain product.

[0068] In addition, the wet particle removal step S320 can remove the matte glaze formed on the surface of the porcelain product by wiping the surface of the porcelain product with a water-absorbent cleaning tool impregnated with a cleaning liquid.

[0069] For example, in the wet particle removal step S320, a hygroscopic cleaning tool (such as a sponge) can be immersed in a cleaning liquid (such as water) to wipe the surface of the porcelain article, thereby removing the particles of the matte glaze formed on the surface of the porcelain article for the second time.

[0070] Figures 8 to 9 A schematic diagram showing the state of the picture in the method of drawing and firing a picture on glaze according to the first embodiment of the present invention according to whether the particle removal step is performed.

[0071] As described above, when the second firing step S200 is fired at the optimal temperature, the matte glaze is in a supercooled state where it is not completely melted, so the matte glaze remains on the surface of the porcelain article in the form of invisible particles.

[0072] Therefore, if the particle removal step S300 is not performed and a picture is directly drawn on the surface of the porcelain article, the particles of the picture drawing pigment and the matte glaze will Figure 8 aggregate together as shown, resulting in abnormal picture drawing. In addition, the particles of the matte glaze will adhere to the brush of the picture drawing tool, causing the picture drawing to be unable to continue.

[0073] In contrast, after performing the particle removal step S300 and directly drawing a picture on the surface of the porcelain article, it can be confirmed that since there is no phenomenon of the particles of the picture pigment and the matte glaze aggregating together, the drawability is greatly improved, as Figure 9 shown.

[0074] After the above particle removal step S300, a picture drawing step S400 is performed, and a picture is drawn on the surface of the porcelain article by applying a pigment composition to the drawing tool.

[0075] This process can prepare a pigment composition for drawing a picture and use this pigment composition to draw a picture on the porcelain article.

[0076] At this time, the pigment composition may include a colored pigment and a transparent glaze, and the weight ratio of the transparent glaze to the colored pigment is about 10:1.5 to 2, which is 20:3 to 4 when converted.

[0077] In the past, it was inclined to directly use colored pigments, but in the case of this embodiment, when using a picture drawing tool to draw a picture, the transparent glaze and the colored pigment can be mixed and used in the above ratio to help evenly coat the pigment and be able to draw a smoother picture.

[0078] In addition, the transparent glaze can be configured to contain 15 wt% or more of phosphorus oxide (P2O5) relative to the total weight of the transparent glaze, and 1 wt% or less of iron oxide (Fe2O3) relative to the total weight of the transparent glaze.

[0079] Then, the third firing step S500 is carried out. After the drawing is dried, glaze is coated on the surface of the porcelain article and firing is carried out.

[0080] In this third firing step S500, the firing process can be carried out at the optimal temperature to maximize the clarity of the image.

[0081] In addition, for this purpose, after coating the transparent glaze, the third firing step S500 can be carried out at a maximum temperature of 1250 °C to 1300 °C.

[0082] As described above, after the second firing step S200 of coating the matte glaze on the porcelain article and firing, the present invention performs a particle removal step S300 of removing the matte glaze particles formed on the surface of the porcelain article. And since a drawing step S400 of drawing a picture on the surface of the porcelain article is carried out after such a particle removal step S300, it is possible to prevent the phenomenon that glaze particles adhere to the drawing tool or glaze particles agglomerate during the drawing process. Therefore, compared with the existing method, it has the advantage of being able to show a very clear, three-dimensional and vivid picture.

[0083] Next, other embodiments of the present invention using various forms of utensils in the particle removal step S300 will be described.

[0084] Figures 10 to 11 FIG. is a schematic view of the state of the jet assist device 100 used in the particle removal step S300 of the overglaze painting and firing method according to the second embodiment of the present invention.

[0085] As Figures 10 to 11 shown, the jet assist device 100 used in the particle removal step S300 of the overglaze painting and firing method according to the second embodiment of the present invention includes a fixing unit 110 and an air jet unit 120.

[0086] The fixing unit 110 is a component that is mounted on the pottery wheel 30 to support the porcelain article 5 and provides a fixing force.

[0087] In this embodiment, the fixing unit 110 is fixed by being pressed from the lower surface of the pottery wheel 30 by a load, and has a form including a fixing portion 111 extending outward, an extension portion 112 extending upward from the outer end of the fixing portion 111, and an auxiliary fixing portion 113 extending inward from the upper end of the extension portion 112 by a predetermined length and fixed at a predetermined position of the pottery wheel 30.

[0088] At this time, a protruding fixing projection 114 can be formed on the auxiliary fixing portion 113 to contact the pottery wheel 30, and a recessed fixing groove 31 can be formed on the pottery wheel 30 so that a part of the fixing projection 114 can be inserted.

[0089] That is, when the fixing part 111 is under the pressure of the load of the potter's wheel 30, by inserting a part of the fixing protrusion 114 into the fixing groove 31, the fixing unit 110 can be stably fixed.

[0090] On the other hand, the fixing unit 110 is provided in the form of being fixed to the fixing part of the potter's wheel 30, and it is necessary to keep it in a fixed state separately from the rotation of the porcelain article 10.

[0091] Therefore, in this embodiment, the fixing protrusion 114 is provided in the form of a bearing so as to be rotatable on the auxiliary fixing part 113, and the fixing groove 31 of the potter's wheel can be formed along a circular path centered on the rotation axis of the potter's wheel 30.

[0092] The air injection unit 120 is connected to the upper part of such a fixing unit 110 and functions to inject compressed air toward the porcelain article 5 side.

[0093] For this purpose, the air injection unit 200 in this embodiment may include: a connection part 121 that is connected to the auxiliary fixing part 113 of the fixing unit 110; and an air flow part 122 that extends longer toward the upper part of the connection part.

[0094] At this time, the air flow part 122 can be formed in a shape corresponding to the curvature of the side surface of the porcelain article 5, or can be made of a flexible material so that its shape can change according to the curvature of the side surfaces of various porcelain articles 5.

[0095] In addition, at a predetermined position of the air flow part 122, a nozzle connection part 123 can be formed so as to be able to connect the nozzle of a compressed air injection tool 40 such as an air gun that injects compressed air, and a plurality of nozzle parts 124 spaced apart from each other in the vertical direction can be formed in the opposite direction of such a nozzle connection part 123.

[0096] That is, an air flow path is formed inside the air flow part 122 through which the compressed air ejected from the nozzle of the compressed air injection tool 40 flows, and the compressed air flowing along the air flow path is ejected onto the surface of the porcelain article 10 through the plurality of nozzle parts 124, so that the matte glaze particles on the surface of the porcelain article 10 can be physically removed.

[0097] On the other hand, as Figure 11 shown, the air flow part 122 of the air injection unit 120 can be formed to be rotatable relative to the fixing unit 110 based on the center point of its lower part.

[0098] Therefore, in this embodiment, the injection angle of the compressed air ejected from the nozzle 124 toward the porcelain article 5 can be changed diversely.

[0099] In this case, the writer can adjust the rotation angle of the air flow unit 122 to match the width / dimension of the porcelain article 5, or spray compressed air onto the porcelain article 5 at a predetermined angle according to the writer's intention.

[0100] In particular, when the air flow unit 122 is set to spray compressed air toward the side end of the porcelain article 5, it is possible to prevent the matte glaze particles removed from the porcelain article 5 by the compressed air from flying toward the writer, and by making the matte glaze particles fly backward, it is possible to minimize the inflow of matte glaze particles into the writer's respiratory system.

[0101] Figure 12 Schematic diagram showing the state of using the hygroscopic cleaning tool 200 in the particle removal step S300 of the overglaze painting and firing method according to the second embodiment of the present invention.

[0102] As Figure 12 shown, in the overglaze painting and firing method according to the second embodiment of the present invention, the hygroscopic cleaning tool 200 used in the particle removal step S300 is integrally formed as a whole, and has a cleaning surface 210 for cleaning the surface of the porcelain article 5, including a curved portion 211 and a chamfered portion 212.

[0103] The curved portion 211 is located at the center of the cleaning surface 210 and has a curved shape that is recessed inward.

[0104] That is, such a curved portion 210 is formed in a shape that facilitates cleaning of the glaze particles remaining in the curved area on the surface of the porcelain article 5.

[0105] In addition, a pair of chamfered portions 212 are provided at intervals above and below the cleaning surface 210 with the curved portion 211 as the center, and are formed in the shape of flat surfaces inclined with respect to the upper and lower surfaces of the hygroscopic cleaning tool 200.

[0106] That is, the chamfered portion 212 is formed in a shape that easily washes away the matte glaze particles remaining in the boundary area where the curvature of the surface of the porcelain article 5 changes sharply.

[0107] In addition, in this embodiment, a pair of chamfered portions 212 provided above and below with the curved portion 211 as the center are described as having the same shape. Of course, differently, a pair of chamfered portions 212 may also be formed in different shapes and areas.

[0108] As described above, the present invention has been illustrated with preferred embodiments. It is obvious to those skilled in the art that, without departing from the spirit or scope of the present invention, the present invention can be implemented in other specific forms in addition to the above embodiments. Therefore, the above embodiments should be regarded as illustrative rather than restrictive. Thus, the present invention is not limited to the above description, but can also be modified within the scope of the appended claims and their equivalents.
