Method for manufacturing pottery with variable shape of abstract pattern and pottery produced by the method}

The present invention relates to a method for manufacturing porcelain molded in a golden color and an abstract pattern using a granite mixed mineral, and a ceramic manufactured by the method thereof. More specifically, the glaze of the glaze by the granite mixed mineral powder is more uniform and The present invention relates to a method for manufacturing porcelain molded in a golden color and a method of manufacturing a porcelain molded in golden color by using a granite mixed mineral that is made uniform and can be molded in a golden color.

Here, the abstract is defined as an irregular, uniform pattern without a specific pattern or pattern.

In general, ceramics are used in a variety of production of various items, from household items such as bowls to ornaments by molding and firing plastic clay raw materials.

Although there are some differences in the manufacturing method of such ceramics depending on the type, the process of mixing and kneading the raw clay, the process of molding the porcelain into a shape desired by the worker to manufacture the kneaded clay, inlaid for the required design, etc. Process of processing the surface of porcelain ware by various techniques of, process of drying moisture remaining in clay, process of pre-baking at a temperature specified in a kiln, process of coloring and painting if necessary, and previously completed process Through the process corresponding to the process of uniformly applying glaze on the surface of the porcelain and the process of completing the final product having a shiny ceramic surface by re-baking the coated porcelain at a specific temperature in a kiln, the desired product for workers and consumers It is manufactured in the form.

The patterns, patterns, and colors of traditionally manufactured ceramics are random (unintended), depending on various conditions, such as the composition ratio of raw materials of clay, the applied decoration and coloring, the type and mixing ratio of glaze applied, and the temperature of firing during chaebol roasting. ), But in order to prevent randomly determining the patterns, patterns, and colors of traditional ceramics according to traditional methods, artificial decoration and coloring and painting processes are applied to produce desired results.

That is, various techniques, such as preventing absorbency and increasing chemical resistance, have been used to apply glaze between the primary and the chaebol roast, so that the surface of the final porcelain is smooth and rigid.

By the way, in the patterns and patterns and colors of the ceramics manufactured according to the prior art as described above, in particular, it is necessary to work to draw the patterns and patterns to correspond to the desired pattern by the worker or the drafter, and to create with different creative designs each time There is a difficult problem.

Inventor 1 of the present invention to solve the problems as described above, "an irregular patterned ceramics and a manufacturing method thereof" (Registration No. 10-1057156; 2011.08.09), and an "unregulated patterned ceramics manufacturing method" (application 10 -2016-0112913; 2016.09.02) was devised, but the prior art of the present inventors did not properly entangle each other on the surface of glazed porcelain porcelain, resulting in irregular and abstract patterns and patterns at random. There is a problem that it is not formed variably, and because it is applied by applying glaze in a state of being baked in a porcelain molded from clay material, there is a problem in that the state of milk is incomplete, uneven and non-uniform, and it is initiated when roasting chaebol There is a problem in that the surface of the porcelain can be produced as a result of the shape being deformed due to thermal deformation.

Due to this problem, the prior art is stably irregular and abstract patterns and patterns are not randomly and variably formed in the final porcelain pottery, and thus the process is in a state in which productivity is deteriorated and the state of defects is not recognized. A serious problem is caused that the yield of the finished ceramics is falling.

In order to solve this problem, the present inventors intend to achieve technical difficulty as a main point by utilizing powders for manufacturing glazes for various purposes and to manufacture ceramics in a stable manufacturing method.

The present invention was devised to be more advanced to solve the above problems, when granite mixed mineral powder is mixed with clay raw material before pre-baking, and then molded into porcelain porcelain, when granite mixed mineral powder glaze of the same component is immersed, it is deposited. And the adhesion rate (power) is improved, so that the stiffness of ceramics and the adhesion rate (absorption) of abstract patterns are improved during firing with a pre-baking process, an electric heating process and an additional gas heating process, and a natural cooling process and a forced cooling process. In addition, it prevents thermal deformation and makes it possible to more uniformly and uniformly coat the glaze with granite mixed mineral powder, as well as sequentially perform electric heating and additional gas heating, natural cooling and forced cooling. The abstract pattern is variable by using a granite mixed mineral that is molded into a golden color. A method of manufacturing a ceramic molded in high golden color and a ceramic manufactured by the method are provided.

In addition, according to the present invention, since the primary and secondary firing processes are stably performed in a kiln by mixing granite mixed mineral powder with a clay raw material, the patterns and patterns formed in the entire process are more reliably maintained. Not only that, the process proceeds quickly and stably, resulting in a method of manufacturing ceramics molded in golden and molded in an abstract pattern using a granite mixed mineral that improves the yield of resultant ceramics and improves productivity. It has a purpose.

In addition, the present invention uses only the granite mixed mineral powder required for glazing oil by collecting only the granite mixed mineral powder that has passed through 1000 mesh or less, so that the patterns and patterns formed in the entire process can maintain a more certain shape. An object of the present invention is to provide a method for manufacturing ceramics molded in golden and molded in an abstract pattern using a granite mixed mineral that forms an optimal colloid that increases the adhesion (mutual intertwined state) and ceramics produced by the method.

In accordance with the above object, the present invention comprises the steps of preparing a primary moulding soil for molding ceramics; Crushing the ore corresponding to the granite mixed mineral containing the rare earth element component and collecting dust of the ore during crushing; Collecting the uniform granite mixed mineral powder by treating the collected dust with 1000 mesh; Mixing the granite mixed mineral powder and the primary moulding soil at a ratio of 5 to 15% by weight and 85 to 95% by weight to form a secondary moulding soil; Shaping the ceramics for daily life and the ceramics for appreciation with the secondary molding clay and preliminarily roasting them in a kiln at a temperature of 800 ° C to 900 ° C for a required time; To prepare the glaze to mix and apply the granite mixed mineral powder and water at a ratio of 15 to 50% by weight and 50 to 85% by weight, and apply it during the time of immersion in the super-baked porcelain to dry the abstract pattern to be adhesively molded. Step and; The glaze-fired ceramics are fired in a kiln at a primary heating temperature required according to an electric heating method, and volatile combustion gas is injected into the kiln to continuously fire at a secondary heating temperature required according to a gas heating method. A heating step; When the second heating temperature is reached, firing of the heating step is stopped to naturally cool to the required primary cooling temperature, and when the primary cooling temperature is reached, a portion of the kiln is opened to discharge residual combustion gas. And a cooling step for forced cooling to the secondary cooling temperature;

The porcelain molded by the secondary water forming soil is burned and the adhesive force applied to the surface of the porcelain is uniformly increased, and the glaze is uniformly adhered and deposited on the porcelain surface, corresponding to the heating step to the cooling step. The abstract pattern is achieved by using a granite mixed mineral characterized by being molded in an abstract pattern and golden color on the surface of the ceramic by a heat treatment process.

Here, the heating step,

An electric heating step of calcining the glazed pottery-coated ceramics in an electric heating method from a kiln to 900 ° C to 980 ° C; It is preferable to include an additional gas heating step in which the volatile combustion gas is injected into the kiln in succession to the first heating step and calcined by an additional combustion gas method for 2 to 3 hours from 1200 ° C to 1300 ° C.

Here, the cooling step,

A natural cooling step of stopping the first and second heating steps after the second heating step to naturally cool to 1000 ° C to 1100 ° C; It is preferable to include a forced cooling step of blocking the combustion gas after the natural cooling and forcibly cooling it to be 300 ° C to 400 ° C for 7 to 8 hours while discharging residual combustion gas by opening a portion of the kiln.

Here, the higher the proportion of the granite mixed mineral powder among the glazes applied in the process and the pattern forming step, the density of the abstract pattern increases proportionally, and the proportion of the granite mixed mineral powder among the applied glazes is low. The proportionally decreases the density of the abstract pattern as it increases,

When the porcelain molded by the secondary water forming soil is prebaked and the glaze is repeatedly adhered to the surface of the porcelain, it is preferable that different abstract patterns are adhered variably each time it is applied.

The present invention is achieved according to another field of the above object by using a granite mixed mineral, characterized in that produced by the above manufacturing method, with an abstract pattern being variable and golden molded ceramics.

The present invention induces so that when the granite mixed mineral powder glaze of the same component is immersed by mixing the granite mixed mineral powder with the clay raw material before the initial grilling, the deposition and adhesion rate (power) is improved. When firing, it leads to the improvement of the stiffness of the ceramics and the adhesion (power) of the abstract pattern, prevents thermal deformation, and makes it possible to make the glaze of the glaze by the granite mixed mineral powder more uniform and even, as well as electric heating Since the process and the additional gas heating process, and the natural cooling process and the forced cooling process are sequentially performed to form a golden color, the adhesive stability of the abstract pattern and the stability of the golden color are maximized, thereby improving productivity and yield.

In addition, according to the present invention, since the adhesion stability of the abstract pattern is maximized every time the pre-baked pottery molded from the secondary molding soil mixed with the granite mixed mineral powder is maximized, the proportion of the granite mixed mineral powder among the glazes is proportional to the higher. As a result, the density of the abstract pattern increases, and the lower the proportion of the granular powder mixture of granite among the glazes, the effect of decreasing the density of the abstract pattern proportionally. It has the effect of creating an abstract pattern.

Hereinafter, with reference to the accompanying drawings, using the granite mixed mineral according to the present invention, the abstract pattern is variable and the method for manufacturing a ceramic molded in golden color and the ceramic produced by the method will be described in detail as follows.

First, as shown in FIG. 5, the mixed mineral is composed of a combination of granite or minerals corresponding to this kind of pulverite, and although slightly different depending on the mineral, SiO ₂ 70 wt% or so, Al ₂ O ₃ 15 including weight% or less, Fe ₂ O ₃ 2.50 wt.% or less, CaO 1.50 wt% or less, MgO 0.60 wt% or less, K ₂ O 4.50 wt% or less, Na ₂ O 3.60 wt% or less, Ba 0.12 wt% or less, and Rare earth elements, such as cerium, dysprosium, gadolinium, lanthanum, neodymium, praseodymium, and samarium, which correspond to trace amounts, are further composed of about 1.39% by weight or more.

Here, the abstract pattern is defined as an irregular, constant pattern without a specific pattern or pattern.

As shown in FIG. 1, a method of manufacturing a pottery in which an abstract pattern is variably formed by using a granite mixed mineral of the present invention is a collecting step (S10), a dust collecting step (S20), a molding step (S30), and a rough roasting step (S40). ), Siyu and pattern forming step (S50), two-stage heating step (S60), two-stage cooling step (S70).

First, an initial primary moulding soil having a required viscosity suitable for molding of ornamental and appreciative or household ceramics is prepared.

In the collecting step (S10), the granite mixed mineral is crushed in a certain space, and only the dispersion and swimming in the air among dust generated during crushing is collected. Such stable dust collection can be said to be the optimal collection method that can provide the finest and most convenient fine powder in bulk.

The dust collection step (S20) is treated with 1000 mesh to form a granite mixed mineral powder of a specific size or less, and the granular mixed mineral powder of a relatively uniform and uniform mass of 1000 mesh or less is precisely collected, thereby improving the stiffness of ceramics in post-treatment. And the abstract pattern can improve the adhesion (power) firmly.

In the forming step (S30), in the molding of ornamental and appreciative or living ceramics, the primary water forming soil and granite mixed mineral powder are each 85 ~ in order to maximize the stiffness and the adhesion (power) of the abstract pattern. Since 95% by weight and 5 to 15% by weight are mixed, a second base molding soil in which granite mixed mineral powder is mixed is formed.

Here, the ratio is the optimal ratio, and in the process of the subsequent oil and pattern forming step, even if the content of the granite mixed mineral powder is somewhat low or high, it improves the stiffness of the porcelain (results of chaebol-baked products) and the abstract of the applied porcelain. It is induced to improve the adhesion rate of the pattern, and in the process of the chaebol roasting step, the defect rate of the pottery (results of chaebol roasted products) is lowered and the formation rate of the abstract pattern is maximized. In addition, there is an effect that the formed abstract pattern is formed from a sharp design to a softer curved pattern.

In the first roasting step (S40), after forming and drying solid ceramics by forming and drying household ceramics and ornamental ceramics on the basis of the secondary moulding soil, they are accommodated in a kiln having a predetermined space to a temperature of 800 ° C. to 900 ° C. Since it is fired for about 6 hours as required, it is manufactured into pottery ceramics and ornamental ceramics.

Since these primitive ceramics are made of secondary molding soil, they prevent thermal deformation and improve their strength, and because granite mixed mineral powder is mixed, granite mixed minerals of the same composition are subsequently processed in the process of siyu and pattern forming. When the powder glaze is immersed, it is induced to improve the deposition and adhesion (power) evenly. In other words, it is to induce to improve the adhesion (power) of the abstract pattern of the applied ceramics evenly.

In addition, when the porcelain molded by the secondary water forming soil is pre-baked, the adhesive force and the stability of the glaze applied to the surface of the porcelain are further increased in the process of the post-oil and pattern forming step. Whenever it is repeated, different abstract patterns adhere variably.

In the siyu and pattern forming step (S50), the granite mixed mineral powder and impurities-removed water are mixed at a ratio of 15 to 50% by weight and 50 to 85% by weight to form a glaze to be applied and applied. When the glaze is applied to the primitive porcelain molded from the secondary base molding soil, the granite mixed mineral powder is uniformly distributed and uniformly dispersed in the water, thereby maintaining a colloidal state that increases the adhesion rate. The immersion method holds the crude oil on the surface of the primitive porcelain for about 10 seconds and then dried until the surface glaze is deposited. Then, as shown in FIG. 2, the abstract pattern gradually appears on the surface of the crude porcelain and is applied and adhered discernably to maintain the pattern.

Here, the abstract pattern adhered to the surface of the first porcelain is identifiably applied and adhered to other abstract patterns that are variable each time. In other words, the variable abstract pattern does not appear to be duplicated even in every pottery.

In addition, the density of the abstract pattern increases proportionately as the proportion of the granite mixed mineral powder among the glazes applied in the forming process and the pattern forming step increases. Conversely, the lower the proportion of the granite mixed mineral powder in the glazed oil, the proportionally the density of the abstract pattern decreases.

In the second-stage heating step (S60), the glazed porcelain-fired porcelain is fired in a kiln at a primary heating temperature required according to an electric heating method, and volatile combustion gas is injected into the kiln to be required according to a gas heating method. It is fired again as it is additionally fired at a second heating temperature. Then, then, when the oil is applied, it is possible to secure a form that minimizes thermal deformation while maintaining the abstract pattern applied and adhered to the surface of the primitive ceramic. The color of the surface of the ceramic can be adjusted according to the degree of gas injection.

In the second stage cooling step (S70), when the second heating temperature is reached, the firing of the second stage heating step (S60) is stopped and naturally cooled to the required primary cooling temperature, and when the primary cooling temperature is reached, Since a part of the kiln is opened and the residual combustion gas is discharged, it is forcibly cooled to a required secondary cooling temperature, so that the surface color of ceramics as shown in FIGS. 3 and 4 can be made golden.

That is, the porcelain molded by the secondary water forming soil is burned and the adhesive force applied to the surface of the porcelain is uniformly increased, and the glaze is uniformly adhered and deposited on the porcelain surface, and the heating step ~ cooling step It is molded into an abstract pattern and golden color on the surface of the porcelain by a heat treatment process corresponding to.
