Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to earthenware style ceramics that could not be obtained using conventional glaze decoration methods, and a method for producing the same.

[Conventional technology]

One of the traditional decoration techniques for finished ceramics is the use of glaze. Products that have been glazed require glaze firing or final firing.

Some glazes are called low-fire glazes or low-heat glazes, which cannot be melted unless they are made from high-temperature skin at 800-900°C or 1200-1300°C, but all ordinary ceramics are made with high-fire glazes and low-heat glazes. Fire-glazed items are limited to special items such as Raku ware.

Therefore, the pigments used for painting are limited to heat-resistant inorganic pigments, and it is completely impossible to use the many organic pigments and dyes that have been developed today.

It was Noh. For this reason, in conventional ceramics, vivid coloring using organic pigments, dyes, etc., and special patterns using synthetic resin adhesives or organic solvents have rarely been applied.

In addition, mass production of ceramic products with the same design is carried out by pasting transfer paper, but the use of this method is limited due to the shape of the molded product, such as uneven or complex shapes. There were many things.

Furthermore, if the transfer paper is wrapped around and attached to the entire surface of a cylindrical object such as a pot, seams may occur or the pattern may not be continuous. Alternatively, if transfer painting was performed only on a part of the cylinder to avoid this phenomenon, the pattern would be cut off depending on the viewing position, causing the product to be front and back, which was often rather inconvenient.

On the other hand, if you compare the functions of the inside and outside of ceramics, they are not necessarily the same. In tea bowls, vases, pots, etc., the inside is often used under harsher conditions than the outside, and performances such as heat resistance, water resistance, stain resistance, and abrasion resistance are required to withstand practical use. . On the other hand, on the outside, emphasis is placed on decoration such as patterns and paintings to attract purchasers, or the value of the item as a work of art is judged. For this reason, the outside often does not require as much practical strength as the inside. Also,
For dishes, ornaments, etc., emphasis is often placed on the decorative appearance rather than the practical strength of both the inside and outside.

From this, it can be seen that in the past, the interior glazes of teacups, vases, pots, etc., and the exterior glazes of dishes, etc., were very simple in decoration, and were streamlined with almost no painting or patterning. There were many.

In view of these circumstances, the present inventors conducted intensive research to see if it was possible to streamline at least the glazing on one side of the outside or inside of ceramics and the accompanying firing process, and as a result, they discovered that recent paint and coating technology Coupled with the remarkable development of
For example, during the production process of ceramic pots, we succeeded in decorating the outer part with paint instead of glaze and firing.

This makes the process and work contents simpler and easier.
This was an immeasurable success in reducing costs, but at the same time it was also possible to develop a new type of decoration that could not be expressed with glaze.

[Purpose of the invention]

One of the objects of the present invention is to provide earthenware style ceramics that could not be obtained using conventional glaze decoration methods, and a method for producing the same.

[Structure of the invention]

That is, the ceramics of the present invention are characterized in that at least one base surface of the ceramics is decorated and painted in a clay color style.

In addition, the manufacturing method for the above ceramics involves pasting metal foil partially on one side of the ceramic base, ■ applying paint containing Rokushishiu pigment to the heart of the surface excluding the metal foil, and ■ making clay with an organic solvent. Apply the abrasive powder on the remaining surface and fix the applied surface. [5] Apply a white-green water-based paint containing adhesive to the entire surface multiple times, ■ Black pigment and red pigment. It is characterized by the fact that it is finished by partially applying paint mixed with pigment.

Hereinafter, for convenience, one of the base surfaces will be described as the outer 71s portion, and the other base surface will be described as the inner IHIS portion.

The outer part of the ceramic before painting and decoration may be bisque-fired, closed-fired, or simply glazed and fired, or the glaze may be subjected to a subsequent hon-yaki process. As long as the inner part of the ceramic is glazed, it does not matter whether it is raw, raku-yaki, glaze-yaki, or honyaki-fired.

As in the above structure, a predetermined decoration is applied with paint, and the types of paint include, for example, lacquers (cellulose derivative paints), synthetic resin paints (especially polyurethane RL paints, etc.), or pigment-containing paints. No transparent paint (
Varnish, clear, etc.) or colored paints containing pigments (enamel, paint, etc.) can be selected as appropriate depending on the use and shape of the ceramic.

As for the painting (film formation) method, brush painting, spray painting, streetcar painting, flow coating, dipping painting, roller painting, powder coating, etc. can be used as appropriate depending on the purpose and shape.

The coating film can be cured using reaction heat or heating (solvent evaporation, oxidative polymerization reaction, thermal condensation reaction, thermal fusion reaction, etc.), or photopolymerization using energy rays such as ultraviolet rays or electron beams. Depending on the type of paint and the purpose and shape of the ceramic, any of these may be used. Particularly in the latter case, the reaction proceeds in a short period of time, resulting in a hard coating film, so it is better to use coatings that can be processed by this method as much as possible. Incidentally, the painting work can be done either manually or automatically by a painting robot.

Regarding the painting process, since the painted surface often already has a simple glaze applied, it is first necessary to apply a brimer to prepare the base (base tone! l). Next, the above-described present invention is carried out after undercoating.

After the brimer, the entire surface is undercoated with black paint, preferably matte black. The matte black base makes it easy to express dirt after various types of painting or layering.

When it comes to metal leaf, gold leaf or silver leaf is easier to express the image of an antique item. However, it goes without saying that brass M = erased M - aluminum foil or other metal foil may also be used. This metal foil only needs to be present in a portion of the product, and can be torn by hand and pasted randomly. The adhesive can be lacquer, varnish, or other suitable material.

Applying Rokushishiu may also be done partially. This color is very dark, so it is best not to apply it over too large a area.

It is sufficient to apply it in spots near the metal foil.

The abrasive grains are made into fine powder in a separate process and then turned into clay using a solvent such as varnish. Using a brush, etc., apply this to the remaining entire surface without any corners. This tapping of the abrasive grains causes roughness, wrinkles, brush marks, etc. to form on the surface, and the clay-like abrasive grains become granular in some places, making it look like soil, sand, mud, pebbles, etc. are on the surface. It appears as though he is in first place. Such a surface condition is immediately fixed.

Next, the food surface is lightly colored automatically. This is a process in which the white edge color paint and water-based adhesive are diluted considerably with water, applied to the entire surface, and wiped with a cloth, which is repeated many times to automatically color the entire surface in a thin layer. As a result, even the surface of the metal foil and rugs takes on a slight tinge of color, giving the piece a strong impression of being a vintage piece as a whole.

Finally, a black powder pigment such as carbon and a red powder pigment such as Ben's are made into a paint state and applied to various places. Where is this on the surface?

〔Example〕

The present invention will be explained in detail below.

A large vase (as shown in the figure) was molded out of clay, dried, and unglazed.The inside and outside of the vase were briefly glazed, and then fired. After the final firing, it was allowed to cool sufficiently to room temperature.

For the overglaze painting, I placed this vase on the potter's wheel, applied lacquer primer to the entire outside, and allowed it to dry thoroughly. Then,
A matte black lacquer was sprayed on the entire exterior as a base coat. After the base lacquer has dried, apply gold ml partially.
was applied using lacquer or varnish as an adhesive.

Next, a paint containing Rokusho 2 as a pigment dissolved in varnish was also partially applied to the outer surface of the jar.

On the other hand, the abrasive grains are ground into a fine powder in a mortar or mortar and mixed with varnish to form a clay-like material. This clay-like abrasive grain is applied to the gold leaf surface 1 above.
It adhered to the surface by applying it to the entire outside surface except Rokusho painted surface 2 by tapping it with a brush.

Then, this clay-like paper powder coated surface 3 was fixed with enamel clear spray 4 to prevent A# from falling off. 6 Next,
Dilute the water-based paint with water-soluble adhesive formulated in white-green color considerably with water, and apply it to the entire outside of the jar many times! I returned it and applied it.

Finally, carbon and wax were mixed with wax, and this was applied to the outer surface of the jar in places to form a stained painted surface 4 and finished.

〔Effect of the invention〕

■The soil-colored pattern according to the present invention has an appearance that is almost the same as that of an old pot from the Bronze Age that was excavated from the soil, and such antique-like products can be produced in a short time with just a few steps. The manufacturing technique is impossible with conventional hangings.

■In particular, tapping marks, brush marks, granulation marks of clay-like paper powder, exposure of the matte black undercoat, and 5-point Roxy of metal foil 1
Wrinkling and roughening of the entire surface, expressing Rokushu rust by coating multiple surfaces with Rokusho color on the entire surface, and applying and fixing a fine powder pigment called benguya carbon to the surface, etc. to achieve appropriate weathering. Decorating the surface of ceramics with stains was completely unthinkable with conventional ceramics.

■ Let the spray-painted undercoat or underpainting dry quickly, then spray paint on top of it with another paint, and repeat the process.
The technique of gradually completing the desired pattern or painting is only possible with quick-drying paints and paints that are already transparent at the time of application.

■Despite the decoration that gives the image of a very high-class antiquity, the present invention does not require any skill, and quality control is easy, and the occurrence of defective products can be kept to a minimum. can.

This is because while the coloring and V-decoration state of glazes can only be confirmed after firing, the present invention uses the earthen color and antique-like image that appears during the painting process as the pattern of the final product. This is because you can work while checking the
As a result, it never happens that all the products are decorated incorrectly as a result of final printing as in the past.

■In the present invention, there is no baking process for finishing, so a wide variety of organic pigments and dyes that cannot be used in glazing can be used in the undercoat and topcoat, making it possible to create very special colors such as soil color. This made it possible to decorate with color.

■Unlike conventional transfer painting methods, even molded products with complex curved surfaces can be decorated with the freedom of the present invention, and the patterns are not uniform, but vary from piece to piece. There is.

■There is no decoration on just one side of a molded product such as transfer paper. In addition, there are no seams or seams, and the decoration according to the present invention can be equally applied to all desired surfaces.

- Since the present invention makes it possible to provide ceramic products such as ashtrays, tiles, and flower vases with clay-colored antique-like images at relatively low prices, it is possible to expect a new increase in purchasing desire.

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to earthenware style ceramics that could not be obtained at all by conventional glaze decoration methods, and a method for producing the same. [Conventional technology] One of the traditional techniques for decorating ceramics is the use of glaze. Products that have been glazed require glaze firing or final firing. Some glazes are called low-heat glazes or low-heat glazes, which require a high temperature of 800-900℃ and 1200-1300''C to melt, but all ordinary ceramics are made with high-heat glazes and low-heat glazes. Fire-glazed items are limited to special items such as Raku ware. Therefore, the pigments used for painting are limited to heat-resistant inorganic pigments, and there are many organic pigments and organic pigments that are being developed today. It was completely impossible to use dyes.For this reason, in conventional ceramics, it was difficult to create vivid colors using pigments and dyes, and special methods using synthetic resin adhesives or organic solvents. In addition, mass production of ceramic products with the same design is carried out by pasting transfer paper, but this method is difficult to apply due to the shape of the molded product, such as uneven or complex shapes. In addition, when wrapping and pasting transfer paper over the entire surface of a cylindrical shape such as a vase, there may be seams or the pattern may not be continuous. Alternatively, to avoid this phenomenon, the transfer painting is applied only to a part of the cylindrical shape, but depending on the viewing position, the pattern may be cut off, causing the product to have two sides, which is often rather inconvenient.On the other hand, ceramics Comparing the functions of the inside and outside of a teacup, they are not necessarily the same.In tea bowls, vases, urns, etc., the inside is often used under harsher conditions than the outside, and has characteristics such as heat resistance, water resistance, stain resistance, Performance such as wear resistance is required to withstand practical use.On the other hand, for the outside, emphasis is placed on decorativeness such as patterns and paintings to attract purchasers, or to judge the value as a work of art. For this reason, the outside often does not require as much practical strength as the inside.Also, for dishes and ornaments, the decorativeness of the exterior is often more important than the practical strength of both the inside and outside. For this reason, in the past, the glaze on the inside of bowls, vases, pots, etc., and the glaze on the outside of plates, etc., were very simple in decoration, and were streamlined with almost no painting or patterning. In view of these circumstances, the inventors of the present invention conducted extensive research to see if it could be possible to streamline at least the glazing of one side of the outside or inside of the ceramics and the accompanying firing process, and as a result of recent research. Coupled with the remarkable development of paint and coating technology,
For example, during the production process of ceramic pots, we succeeded in decorating the outer part with paint instead of glaze and firing. This makes the process and work contents clearer, simpler, and easier.
This was an immeasurable success in reducing costs, but at the same time it was also possible to develop a new type of decoration that could not be expressed with glaze. [Object of the invention] The present invention is one of them, and in the conventional glaze decoration method, all (
The purpose of this project is to provide earthenware style ceramics that have not been available before, as well as a method for producing them. [Structure of the Invention] That is, the ceramic of the present invention is characterized in that at least one base surface of the ceramic is decorated and painted in a clay color style. In addition, the manufacturing method for the above-mentioned ceramics involves: (1) pasting metal foil partially on one side of the ceramic body, (2) applying Rokushishiu pigment-containing paint here and there on the surface excluding the metal foil, and (2) applying clay-like paint using an organic solvent. Apply the abrasive grains on the remaining surface, fix the applied surface, and then apply multiple coats of a water-based paint containing a white-green adhesive to the entire surface.■ Color-based pigment and red. It is characterized by the fact that it is finished by partially applying paint mixed with pigments. For convenience, one of the base surfaces will be described as an outer part and the other base surface will be referred to as an inner part. The outer part of the ceramic before painting and decoration may be unglazed, fired, or simply glazed and fired, or the hanging may be subjected to a post-glaze firing process. As long as the inner part of the ceramic is glazed, it does not matter whether it is raw, raku-yaki, glaze-yaki, or honyaki-fired. The soil is decorated with paint on the outer surface of the bear as shown in the above composition. Derivative paints) 1 Synthetic wood W! Paints (especially polyurethane resin paints, etc.), or transparent paints that do not contain pigments (varnishes, clears, etc.) or colored paints that contain pigments (enamels,
Paint, etc.) can be selected as appropriate depending on the purpose and shape of the ceramic. As for the coating (coating film formation) method, brush coating, spray coating, Seiden coating, 70-coating, dipping coating, roller coating, powder coating, etc. can be used as appropriate depending on the purpose and shape. The coating film can be cured using reaction heat or heating (solvent evaporation, oxidative polymerization reaction, thermal condensation reaction, thermal fusion reaction, etc.), or photo-curing using energy rays such as ultraviolet rays or electron beams. Depending on the type of paint, use and shape of the ceramics, it may be legal. Particularly in the latter case, the reaction proceeds in a short period of time, resulting in a hard coating film, so it is better to use coatings that can be processed by this method as much as possible. Incidentally, the painting work can be performed either as a child work or as automatic painting by a painting robot. Regarding the painting process, since the painted surface often already has a simple glaze applied, it is necessary to first apply a primer to prepare the surface. Next, the above-described present invention is carried out after undercoating. After the primer, the entire surface is undercoated with black paint, but 21-color paint is preferable for black. The matte black base makes it easy to express dirt after various types of painting or layering. As for the metal foil, it is easier to express the image of an antique than gold or silver foil, but it goes without saying that brass foil, copper foil, aluminum foil, and other metal foils may also be used. This gold foil only needs to be present in a portion of the product, and can be torn by hand and pasted randomly. The adhesive may be lacquer, varnish, or other appropriate adhesive. You can only apply a single layer of Roxy locally; this color is very dark, so it's best not to apply it over a large area. It is sufficient to apply the metal foil in spots nearby. The abrasive grains are made into fine powder in a separate process and then turned into clay using a solvent such as varnish. Using a brush, etc., apply this to the remaining entire surface without any corners. This pounding and painting of the abrasive grains forms rough texture patterns, wrinkle patterns, brush marks, etc. on the surface, and the clay-like abrasive grains become granular in places, making them look like dirt.
It appears as if sand, mud, pebbles, etc. are attached to the surface. Such a surface condition is immediately fixed. Next, turn the whole surface of the first one a light greenish color. This is a process in which the white line color paint and water-based adhesive are diluted considerably with water, applied to the entire surface, and wiped with a cloth, which is repeated many times to give the entire surface a light green color. As a result, even the surface of the metal foil and rokushishiu begins to take on a light greenish tinge, giving the object a strong impression of being a vintage piece as a whole. Finally, a black powder pigment such as carbon and a red powder pigment such as Ben's are made into a paint state and applied to various places.

A large pot was molded out of clay, dried, and unglazed.The inside and outside of the pot were briefly glazed, and then fired. After the final firing, it was allowed to cool sufficiently to room temperature. For overglaze painting, I placed this vase on a potter's wheel, applied a lacquer primer to the entire outside, and allowed it to dry thoroughly. Then,
A matte black lacquer was sprayed on the entire exterior as a base coat. After the base lacquer had dried, gold leaf was applied locally with lacquer or varnish as an adhesive. Next, a paint containing Rokusho as a pigment dissolved in varnish was applied partially to the outside of the vase. On the other hand, grind the abrasive grains into a fine powder in a mortar or sabotachi and mix them with 7 varnish to form a clay-like mixture. The clay-like abrasive grains are applied by tapping with a brush to the entire outer surface except for the gold foil surface and the Rokusho coated surface. At this time, granulated abrasive grains adhered to the surface in a scattered manner. The surface coated with clay-like abrasive grains was fixed by spray painting with enamel clear (as shown in 1).Next, water-based paint containing a water-soluble adhesive formulated in natural green was diluted considerably with water, and It was applied repeatedly to the entire outside of the vase many times.Finally, carbon and wax were mixed with wax and this was applied to the outside of the vase here and there to form a dirty painted surface.[Effects of the invention] ■The soil-colored pattern according to the present invention has an appearance that is almost the same as that of an old pot from the Bronze Age that was excavated from the soil, and such antique-like products can be produced in a short time with just a few steps. This technique cannot be applied using traditional glazing methods.■Especially, the surface of the surface of the color base, such as tapping marks, brush marks, ゛, upper abrasive grain granulation marks, and matte undercoating! 9.
