Description

TECHNICAL FIELD [0001] The present invention relates to a method of forming a ceramic pattern,

The present invention relates to a method of forming patterns of ceramics that can clearly and clearly produce patterns of intended shapes without applying glazes of different colors to the surface of the ceramics.

Pottery was one of the earliest invented artifacts as human beings began their cultural life, and developed into various forms through long years. In particular, ceramics ceramics have been loved not only in terms of practicality but also in decorative aspects due to the clear sound of ceramic materials and the pure sound of beating.

Therefore, in addition to efforts to improve the practical aspects through the material, manufacturing process and design development of ceramic ceramics, the development of shapes and surface shapes has been proceeded to improve the decorative surface. Particularly, in the development of technology for decorative purpose, many attempts have been made in terms of being able to create a noble image that can not be achieved by other materials due to the unique physical properties of ceramics. In this way, various patterns have been directly drawn on the surface of the unglazed pottery, or a method in which the engraved or embossed areas are filled with other colors or materials have been developed and used.

A brief description of a method for manufacturing ceramics will be given.

First, ceramics are made of dough (kneading) after defending raw materials such as clay, which is a main component of ceramics. The raw material is placed on a spinning wheel, the potter (operator) forms the desired shape, and if necessary, it is dried through a bending machine or sculpture. When the drying of the earthenware is finished, it is baked at 700 ~ 900 ℃ depending on the type of earthenware to be baked.

The unglazed earthenware is painted on the surface of the earthenware, glued to the surface of the earthenware, embossed or embossed, and then glazed and glazed again. This chaebol roasting is a step of baking until the glaze on the earthenware is melted and it is like melting the glass.

The melted glaze is fused to the surface of the earthenware by reacting with the earthenware, and the glaze components are mutually compatible to form the surface of the earthenware. The glaze to be used at this time differs from the composition of the glaze according to the application such as blue magnetic powder, white magnetic powder, powder magnetic powder and sulfur magnetic powder. If these components and their composition ratios are not properly set, incomplete fusing on the surface of the finished pottery or cracking of the surface may occur.

In general, the purpose of the glaze is to make the surface of the ceramics harder and smoother, and in particular to protect various substances in the liquid state stored in the container.

The various glazes traditionally traditionally introduced have the purpose of smoothly forming the surface of ceramics such as blue, white, bronze, and sulfur, and if the pot is intended to form patterns on the ceramic, ), Or engraving engraved or embossed, or using various pigments on the surface of the pottery, or by drawing a picture on the surface.

However, the pattern formation of the pottery is generally performed by forming an abstract engraved or embossed pattern on the earthenware before the pre-baking, or by embossing a pattern of a specific pattern on the earthenware to form the pattern of the mold, The color of the pottery was obtained by applying a monochromatic glaze to the surface of the earthenware after the unglacial or applying a glaze of different color to each part.

However, since the pattern or color of the ceramics expressed in this way exhibits an artificial and unnatural expressive beauty, a method of directing a new technique is required for the appearance of the ceramics, which requires a unique and simple natural beauty.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, It will be possible. The present invention is capable of various modifications and various forms, and specific embodiments are illustrated in the drawings and described in detail in the text. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed, 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 method of forming a pattern according to the present invention includes forming a relief pattern mounted on a surface of a ceramics-shaped article so that an upper end of the cabinet is formed at a predetermined angle or less. In the step of applying a glaze, So that the thickness of the glaze is relatively thin. Therefore, the finished part of the ceramics after the second firing step and the embossed pattern are colored differently, and a pattern or pattern is formed on the surface of the ceramics.

More specifically, the article formed by molding the clay is subjected to a shaping step. In this process, a triangular embossed pattern is formed on the surface of the article so as to have a tapered side without a flat upper side. The embossed pattern can be formed by manual operation of a pottery. For this purpose, a pottery hand technique for keeping the embossed pattern constant is required. In addition, a tool may be utilized for the embossing. It is preferable that the embossed pattern 11 (see FIG. 3) is mounted in a pointed shape such that the applied glaze can not be easily stored, and the upper cabinet angle A of the embossed pattern is preferably 10 to 20 degrees. As the upper internal angle A of the embossed pattern 11 is closer to the plane (180 degrees), the applied glaze adheres to the current position to maintain its thickness. As the upper internal angle A becomes narrower, (Distance between P1 and P2) of the boss portion 11 becomes narrow, so that the visual distinction between the portion of the boss 11 and the portion different in hue becomes unclear.

Here, the 'triangle' of the embossed pattern refers to a shape having not only a triangle but also three corners (including both a bent shape and a curved shape). 6 (a cross-sectional view showing various shapes of embossed patterns in the pattern forming method according to the present invention), the embossed pattern 10 having a triangular cross section according to the present invention is shown in FIG. 6 (a) (B) a triangular shape shown in the drawing, and (c) a tapered side shown in the drawing may be a concave horn shape.

The height h of the boss 11 is preferably equal to or greater than the thickness of the glaze applied so that the height h of the boss 11 is 2 to 5 mm based on the forming point of the boss 11. When the height h of the relief pattern 11 is increased and the side width of the relief pattern 11 (the arc of P3 to P1 and the pitch of P3 to P2) of the relief pattern 11 is made to have a sufficient area for glaze adhesion, The thickness of the glaze applied to the pattern 11 does not differ from that of the glaze on the flat portion. If the height h of the relief pattern 11 is lowered, the emboss pattern 11 is buried in the glaze applied to the flat portion, so that the difference in glaze thickness due to the formation of the relief pattern 11 can not be realized .

As a result, it is preferable that the width of the tapered surface (P1 to P3 arc, P2 to P3 arc) of the relief pattern 11 is about 2.0 to 5.0 mm, and the application area of the glaze is not sufficient for glaze adhesion.

The upper end interior angle A of the relief pattern 11 according to the present invention is determined by the first bottom point P1 and the second bottom point P2 of the relief pattern 11 and the upper end point P3 ) (Hereinafter, referred to as 'intersection angle') of each line segment (P1 to P3 line segment and P2 to P3 line segment). 3, the shape of the embossed pattern 11 from P1 to P3 and the shape of the embossed pattern 11 of P2 to P3 can be convex curves, concave curves in the molding process, or straight lines.

When the embossed pattern is completed on the object, the object is dried and the first firing step corresponding to the ungukugi is performed, and the glaze is applied on the surface of the fired object.

In the glaze application step, the glaze coated on the surface of the object partially flows in the direction of the flat part from the embossed pattern part, and the thickness of the applied glaze on the embossed pattern becomes relatively thin compared to the thickness of the applied glaze on the flat part. On the other hand, for the vignetting of the forming pattern, the coating glaze is applied with a glaze oil having a fluidity and a glaze oil.

When the application of the glaze to the article is completed, the second firing proceeds, and the glaze applied to the article is denatured by denaturation in the second firing process. At this time, the glaze on the planar portion and the glaze on the embossed pattern are different in discoloration due to different thicknesses, and the completed pottery has a specific pattern according to the embossed pattern. On the other hand, the embossed portion of the ceramics finished from the object has a color different from that of the flat portion, but the gloss effect due to the residual glaze is maintained as it is.

The method of forming a pattern of a ceramic according to the present invention as described above includes a ceramic molding step of molding and burning a sufficient volume of powdery clay, white clay, celadon clay, and the like into a specific shape and drying the ceramics; And a second firing step of glazing the pottery to which the glaze is applied, and a second firing step of glazing the pottery coated with the glaze, DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flow chart showing an embodiment of a pattern forming method according to the present invention. FIG. 2 is a view showing a process of forming a ceramic formed by a pattern forming method according to the present invention, R of FIG. 1, which is an enlarged cross-sectional view.

An example according to the present invention will be described by taking a white clay as an example. However, various kinds of clay such as coal clay, celadon clay, kaolin, clay, and clay can be used as materials for ceramics.

S10; Porcelain molding step

Stool (step of stepping on clay by hand or kneading by hand) A white clay is seated on a rotating plate of a spinning wheel and rotated to form a product 10 in the form of a lid of a ceramic as shown in FIG. 2 (a). For reference, the article 10 of the present embodiment has a dome shape and a ball shaped handle at the top. For reference, the stool is used to remove the air in the clay by evenly mixing the water into the clay. The material molded using the stony clay stably maintains the molding state, and cracks of the finished pottery . After the molding is completed, the object 10 is dried for a predetermined time.

The article 10 of the present embodiment is formed by using a spindle or the like, or a method of molding by using a props or the like. Methods for molding using a props include punching, clay molding, clay molding, and the like.

In this embodiment, the article 10 is naturally dried for 24 hours (day), but the molded article 10 can be naturally dried for 8 to 25 hours in terms of the type of clay and the molding form.

S20; Stage of ceramics shaping

The shape and surface of the article 10 molded in the ceramics forming step are shaped. The pre-shaping article 10 unnecessarily protrudes or forms a rough surface in the molding process. The surface of the article 10 is smoothly arranged by hand, or shaped using tools or the like.

On the thus-shaped surface, the embossed pattern 11 is formed in the designated shape at the position where the pattern is to be formed.

As shown in Fig. 2 (b), the embossed pattern 11 of the present embodiment is formed in a circular shape on the upper surface of the article 10, and the upper end of the embossed pattern 11 ) Was mounted so as to maintain 13 to 15 degrees. In order to minimize the degree of adhesion of the glaze applied to the portion of the boss 11, the present embodiment mounts the boss 11 so that the height of the boss 11 is maintained at 2 to 3 mm.

When the shaping of the article 10 is completed, the article 10 is sufficiently dried for 3 to 7 days in the shade.

S30; Primary firing step

The shaped article 10 after completion of the shaping is slowly heated for 12 hours and then baked to 850 占 폚.

When the temperature reaches 850 ℃, stop the fire and slowly cool down for 1 day.

S40; Glaze application step

The surface of the first fired product (10) is removed with contaminants such as dust and the surface is coated with fluid refining oil.

In this embodiment, the glaze is applied by immersing the object 10 in a glaze (glaze), through which the glaze is applied together with the blaze pattern 11 and the flat portion.

The glaze is applied and the object 10 is dried for some time in the shade.

S50; Second firing step

After the glaze-coated article 10 is fired at a raised temperature, the glaze is heated at 950 ° C to convert the glaze to a fuming salt, and then the temperature is raised to 1280 ° C to display the color of the glaze. Subsequently, when the temperature reaches 1280 ° C., the temperature is lowered to 1180 ° C. so that the flow of the glaze and the discoloration of the portion of the embossed pattern (11) are completely completed, and after 30 minutes, the firing is stopped and naturally cooled at room temperature for 48 hours.

During the second firing process, the glaze applied to the object 10 is oxidized and expresses a unique color. At this time, the color and the planar pattern portion of the embossed pattern 11 of the object 10 show different oxidation of the glaze Different colors are produced.

As a result, as shown in FIG. 4 (an image showing an embodiment of a ceramic produced by the pattern formation method according to the present invention), the finished ceramic 10 'has a first pattern 11' , And the first pattern 11 'has a clear and clear shape.

For reference, the second pattern 12 'formed along the periphery of the ceramic 10' is separated by partially wiping the applied glaze, and the third pattern 13 'formed along the periphery of the handle is separated Which is naturally formed. However, unlike the first pattern 11 ', the boundary of the third pattern 13' is unclear. Therefore, it can be confirmed that the first pattern 11 ', which is a pattern formed on the basis of the embossed pattern 11 according to the present invention, is very high and excellent.

In addition, as shown in FIG. 5 (an image showing another embodiment of the ceramic produced by the pattern forming method according to the present invention), the surface of the ceramic body 20 may be provided with various types of ceramics 5 patterns 22 can be formed. For reference, the fourth pattern 21 is a pattern formed at the edge of the edge of the ceramic 20, and is a pattern formed by artificially wiping the applied glaze.

4 and 5, the pattern formation method according to the present invention is a technique for producing a definite pattern at a designated position in a plane portion of a ceramic.

FIG. 7 is a cross-sectional view illustrating a process of forming a emboss pattern in the pattern forming method according to the present invention. Referring to FIG.

This embodiment forms the heel 12 so that the portion where the boss 11 will be formed is convex in the ceramics forming step S10. In the present embodiment, since the object 10 is formed in a rotating manner using a spindle, the heel 12 is also formed in a concentric shape.

7 (a), the operator places the two fingers F and F 'on both sides of the heel 12 and rotates the spindle while rotating the spindle, as shown in Fig. 7 (a) b) The two fingers F and F 'are collected towards the center of the heel 12 as shown in the figure. In this process, the clay of the heel portion 12 is gathered and mounted between the two fingers F and F '.

Thereafter, the two fingers F and F 'are kept in contact with each other so that the two fingers F and F' are joined to each other, as shown in FIG. 7 (c). At this time, since the two fingers F and F 'are formed in a cross-sectional shape having a triangular cross-sectional shape, a boss 11 corresponding to the gap is formed on the surface of the object 10. It is also possible to prevent the surface of the object 10 from being concaved in the process of forming the bumpy pattern 11 by the clay in the preformed heel portion 12.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
