BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to building materials such as tiles and roof tiles, sanitary ware such as toilet bowls and washbasins, and tableware, figurines and other pottery, and to marble etc. The present invention relates to a method for producing a pottery product which can be provided with a visible flow pattern.

2. Description of the Related Art Conventionally, in order to produce wares made to look like marble, the procedure of applying glaze to the molded body (before firing) by repeating fluttering is repeated for each of a plurality of glazes of different colors. I was taking steps such as baking. That is, since the glaze that is in the stage of going through the firing process is in a state where glazes of different colors are laminated in multiple layers, when each glaze melts out during firing, the glazes react with each other in some areas. It became a blended color, and in some other part, each glaze appeared alone and a flow pattern in which multiple colors were mixed was formed, and this had a marble-like appearance as a whole.

[0003]

The conventional methods for producing wares have the following drawbacks. That is, since various kinds of gases were dissolved in the glaze from the beginning, it was easy for these gases to be ejected by firing to generate pinholes, burrs and the like on the surface of the pattern of the pottery. Moreover, since the glaze is applied multiple times, it is easy for air to be trapped between the glaze layers, resulting in relatively large dents on the pattern surface of the pottery after firing. There was also something to do. In order to prevent these problems, the glaze coating thickness had to be made considerably thick, but therefore the glaze work was troublesome and the time required for it was prolonged. In addition, the glazes of the respective colors were unidirectional in the flow that occurred during firing, and there was little variation as a marble-like pattern.

The present invention has been made in view of the above circumstances, and it is possible to prevent the generation of pinholes, bumps, and relatively large dents, and to provide variations in patterning (not limited to marble tones). It is an object of the present invention to provide a method for producing a baked product having a flow pattern (hereinafter, referred to as a method of the present invention) capable of enriching a).

[0005]

The gist of the method of the present invention is that the color of the pigment is different in the decorative raw material liquid which is made into a slurry by mixing the binder liquid and the pigment into the kneaded clay for forming the ware. Prepare a plurality of types for each item, inject each of the decorative raw material liquids into the container, and make the liquid surface of the mixed state such that at least two of the individual colors or the fusion colors remain, and A certain sheet material is brought into contact with the liquid surface in the container to adsorb the decorative raw material liquid, and the sheet material is attached to the molded product of the baked product so as to conform to the surface shape, and the product is baked. There is a point to do.

In the method of the present invention, after the sheet material is attached to the unfired molded article of the pottery, the decorative raw material liquid held in the sheet material waits for the migration to the molded article side. Alternatively, the sheet material may be peeled off from the molded body, a transparent glaze may be applied to the surface of the molded body, and the transparent glaze may be baked.

[0007]

FUNCTION The decorative raw material liquid is colored by the pigment itself which is one of its compositions, unlike the glaze which is colored by firing. Therefore, it is extremely unlikely that pinholes or burrs are generated even after firing. Further, since the decorative raw material liquid is not laminated in a plurality of layers on the molded body, no large dent is generated. By the way, since the decorative raw material liquid is in the form of slurry (slurry), when a plurality of types of pigments having different colors are poured into one container and mixed, the mixed appearance looks like a sumi-fashi. It becomes natural (non-geometric) and draws fantastical figures. Therefore, by adsorbing the above mixed raw material liquid for decoration on the sheet material and adhering it to the surface of the molded body, it is possible to transfer a natural and fantastic figure to the surface of the molded body as it is. it can. Therefore, when the molded body is fired, an extremely aesthetic fired product having a flow pattern can be obtained. Infinite development can be expected by changing the color selection, the number of uses, and the mixing state of the decorative raw material liquid, so that the variations of the obtained baked products also have infinite spread.

When the sheet material is adhered to the molded body in the above procedure, the decorative raw material liquid held on the sheet material moves to the molded body side, and eventually all of it becomes the molded body. Will be retained. Therefore, it is possible to peel the sheet material from the molded body with this bear, and the molded body may be baked as it is. In addition, prior to this firing, if a transparent glaze (colorless transparent or coloring inducement) is applied to the surface of the molded article, that is, the surface of the coating film of the decorative raw material liquid, the fired product obtained after firing will also have a flow pattern. It becomes more aesthetic by adding depth and gloss.

[0009]

The present invention will be described below with reference to the drawings showing the embodiments thereof. FIG. 1 is a schematic diagram drawn so that the procedure of the method of the present invention can be easily understood. First, as shown in the uppermost part of the figure, a binder liquid 3 is prepared by dissolving starch paste 1 and the like with water 2. Then, a pigment raw material 5 of the same quality as that used for forming a molded body of burned material, a pigment 4 having an appropriate coloring, and a binder liquid 3 prepared as described above are mixed to prepare a decorative raw material liquid 6 To manufacture. The decoration raw material liquid 6 has a viscosity of 200.
It is necessary to prepare a slurry (slurry) of about 0 centipoise. However, if the viscosity is too low, insufficient holding may occur during adsorption to the sheet material 8 which will be described later, and on the other hand, if the viscosity is too high, holding may be impossible, so caution is required. Further, as the decorative raw material liquid 6, a plurality of kinds (6A, 6B) of different coloring of the pigment 4 are used.
Be prepared.

Next, the decoration raw material liquids 6A and 6B of each of these colors (at least two colors) are poured into one container 7 in appropriate amounts. After the injection, the container 7 may be rotated or shaken, the decorative raw material liquids 6A and 6B in the container 7 may be directly and lightly stirred, or the liquid surface may be undulated by blowing compressed air. The mixed state is such that each individual color still remains. For example, a large amount of white is used as the decorative raw material liquid 6A
It is assumed that a small amount of red is used as. In this case, both colors may be melted to form a pink area in a part of the container 7, but if the entire area of the container 7 is dyed in pink, it may be a pattern. Absent. Therefore, in the container 7, a region where white or red (only one of them may be left) remains as it is on the liquid surface is required. That is, the state is such that a red or pink striped pattern or spiral pattern is formed on a white background, or a white or red striped pattern or spiral pattern is formed on a pink background.

When the work up to this point is completed, the water-absorbing sheet material 8 made of woven cloth, non-woven cloth, paper or the like is gently brought into contact with the liquid surface in the container 7. In practice, the sheet material 8 may be floated on the liquid surface. As a result, the decorative raw material liquids (6A and 6B) in a mixed state on the liquid surface in the container 7 are adsorbed and held on the sheet material 8 in the mixed state as it is. It is sufficient that the decoration raw material liquid (6A and 6B) adheres to the surface of the sheet material 8 by about 1 mm, and thus the sheet material 8 is taken out from the container 7 at this point. The sheet material 8 is made to conform to the surface shape of the molded article 9 before firing in the pottery, before or after the retained decoration raw material liquid (6A, 6B) is brought to an appropriate dry state or not. Stick it on. For example, in the present embodiment, the case where the molded body 9 is a flat tile-shaped green body or the like is shown, but in this case, the sheet material 8 is attached so as to come into close contact with the four circumferential side surfaces of the molded body 9. You can The raw material liquid for decoration (6A, 6A
In drying the sheet material 8 impregnated in B),
It is preferable that the degree of dryness is adjusted so as to be the same as the water content required for the molded body 9 itself (usually about 4%).

The thus-obtained molded body 9 is fired on the basis of firing conditions (method, temperature, time, etc.) according to its thickness, shape and material. In addition, even if the sheet material 8 is fired with the surface of the molded body 9 stuck to the surface, the sheet material 8 is burned off by the firing, and the fired product after firing is not adversely affected.

However, the sheet material 8 may be separated from the molded body 9 before firing. That is, the molded body 9
When the sheet material 8 in the undried state is attached to
After that, the decorative raw material liquid (6
A and 6B) gradually move into the molded body 9, and eventually all of them are held by the molded body 9. Therefore, at this time, the sheet material 8 can be peeled off by itself. The molded body 9 from which the sheet material 8 has been peeled off can be baked as it is, but the surface of the molded body 9 (the surface of the coating of the decorative raw material liquid) is transparent (colorless or transparent). It is also possible to bake after applying the glaze. In this way, the flow pattern obtained in the fired product after firing is added with depth and gloss, which makes it more aesthetic. As shown in FIG. 2, the ware 10 (tile) obtained by the method of the present invention has a natural and fantastic flow pattern on the entire surface thereof.

As described above, the method of the present invention is applied to building materials such as tiles (including accessories) and roof tiles, sanitary ware such as toilet bowls and washbasins, and tableware, figurines and other pottery products in general. It can be implemented. Further, the pattern applied by the method of the present invention is not limited to the existing pattern such as a marble tone, but allows any flow pattern including an imaginary and fantasy pattern. As described above, the detailed configuration of the method of the present invention can be appropriately changed according to the embodiment.

[0015]

As is apparent from the above description, according to the method for producing a pottery product according to the present invention, a pottery product having a flow pattern is produced without generating pinholes, burrs, dents, and the like. Is something that can be done. Also, the pattern obtained by mixing the decorative raw material liquids of different colors with each other is a natural and fantastic striped pattern or swirl pattern, and gives a more similar feeling as a marble tone. Moreover, the pattern can be provided even for wares having a complicated uneven shape, and its workability is similar to that when a simple shape such as a flat plate is provided with the pattern. It's as easy as ever. In addition, since it is expected to have unlimited development in changing the color selection of the decorative raw material liquid, the number of uses, and the mixing status, the pattern variations of the obtained decorative tiles can be endlessly expanded, and many other excellent advantages are obtained.
