2. Description of the Related Art Shippo-yaki has long been known as a traditional handicraft, and has been widely used as a handicraft and ornament. One of the cloisonne ware is wired cloisonne ware. In this method, silver wire or brass wire is implanted on the surface of the base with a base glaze layer formed on a copper plate to form a predetermined pattern pattern, and cloisonne glaze of various colors is placed inside and outside the block and fired It has a glassy transparency, weight, and elegance, and gives a pleasant impression by appealing to the taste and taste of the viewer. There are various other types of cloisonne cloisonne such as wireless cloisonne, transparent cloisonne. These traditional techniques, cloisonne ware, require a lot of time to work in addition to the skill required to make them, and they are expensive, but they are complex, delicate and dense, and the colors are subtle. There is a limit in obtaining such products, and it has been difficult to immediately respond to diversifying customer needs, changing needs, and the like.

[0003] On the other hand, there is a more convenient technique called Ginzari Cloisonne. In this method, an opaque base glaze is applied to a copper plate, a pressed silver foil is closely adhered to the glaze and baked, and then a colored cloisonne glaze is placed on a desired portion of the mold to be baked. However, there is a limit in obtaining a color with a small depth, a complicated and delicate and dense pattern, and a subtle coloration.

Further, conventionally, enamel transfer printing and screen cloisonne firing have been used as simple and large-scale and inexpensive techniques. In the enamel transfer firing, an enamel glaze layer is applied to a metal plate, transfer paper is adhered to the enamel glaze layer, and then fired. Screen Cloisonne ware is a product in which a color pattern is printed by a screen printing plate on an enamel glaze layer and then fired. All of these have a flat color pattern, have no depth, are hard to attract interest, and have low value as commercial products.

[0005]

SUMMARY OF THE INVENTION The present invention provides a vitreous clarity, weight and elegance unique to cloisonne products, which cannot be obtained by the above-mentioned conventional method for producing cloisonne products.

[0006]

According to the present invention, a transfer layer is formed on a material base having a transparent upper glaze layer formed on a material having at least a silver layer on the surface. And then forming a transparent finish layer .

More specifically, the following steps are performed, which will be described step by step.

First, a. Copper, iron, metal ingots made of aluminum or the like is formed on the necessary type as cloisonne ware products and cloisonne matrix (Cloisonne green body forming step). As the shape of the base, various shapes such as a plate-like shape, a pot-like shape, accessories, insignia and the like, which are the shapes of ordinary cloisonne products, can be adopted.

B. The base material is provided with a glaze such as a cloisonne glaze or an enamel glaze for the base and fired (a base glaze layer forming step on the base. The glaze is preferably opaque when fired. The glaze may be applied by any of various methods, such as coating, sprinkling, dipping, etc., as appropriate. subjecting the entire surface if necessary. and the firing depending on the shape of cloisonne ware products,
Usually, it takes about 2 to 10 minutes at a temperature of about 700 to 900 ° C.

C. A silver foil is stuck on the surface of the base glaze layer obtained in the above process, and the material is baked to form a material base (silver foil sticking culm). The thickness of the silver foil is 3 / 1000-
The thickness is preferably about 8/1000 mm, but is not limited to this. The silver foil may be attached to the entire surface of the base glaze layer or to a part thereof, since the silver foil may be attached to a portion where the required decorative effect is to be exhibited. Then, it is adhered using cloth glue or CMC (chemical glue), but it is necessary to prevent air from entering or remaining between the silver foil and the surface of the base glaze layer at the time of lamination. Otherwise, since the sticking is not perfect, the air remaining by baking will expand and large irregularities will occur, and the integration of baking between the silver foil and the surface of the base glaze layer will be insufficient,
Or, in some cases, it may be damaged. Because of this, a fine hole is provided on the entire surface of the silver foil,
It is desirable to prevent air from remaining or the like by expelling air from the fine holes at the time of sticking. However, fine irregularities on the surface of the silver foil are rather desirable because they enhance the light reflection effect. Subsequent to the attachment of the silver foil, baking is performed at a temperature of about 700 to 900 ° C. for about 2 to 10 minutes to bake the silver foil on the base glaze layer.

D. A glaze such as a transparent cloisonne glaze is applied to the surface of the silver foil layer obtained in the silver foil sticking step and fired (Uechi glaze layer forming step). The glaze is 75/1000
It is desirable to obtain a uniform upper glaze layer, which is ground to a particle size of about 250/1000 mm , and is applied by uniformly sprinkling the surface of the silver foil layer until the glaze is completely deposited. At a temperature of about 700 to 900 ° C.,
Bake for about 10 minutes. The application and baking of the upper glaze layer is performed a plurality of times as necessary if one time is insufficient.

The above steps a to d constitute the steps for preparing the material base of the present invention.

The material base can be obtained by the following method in addition to the above method.
That is, subjected to silver plating by direct electroforming technique on the entire surface or part of the surface of the metal bullion green body was fired after applying an undercoat for glaze on the back surface, then, <br/> the surface needed Kamiji those that have been fired after applying a transparent glaze use, or on the rear surface of the 1/10 to 10/10 mm having a thickness of about sILVER green body was fired after applying an undercoat for glaze, then, necessary to
It is also possible to apply a transparent glaze for the upper layer on the surface and then fire it. The application and firing conditions of the base glaze and the upper glaze in these cases are almost the same as those of the silver foil. In these methods, the underglaze layer on the back surface and the upper glaze layer on the front surface can be simultaneously fired, if necessary.

Then, e. A transfer layer is applied to the material base surface using a transfer paper and baked (transfer layer applying step). As for the transfer paper, the enamel transfer paper is baked at the temperature, time,
Although it is desirable from the color development conditions and the like, the present invention is not limited to this, and the picture pattern is preferably a multicolor printed pattern, but is not limited to this, and may be a single-color dark and light printed pattern. In transfer using enamel transfer paper, transfer paper is attached so that air does not remain between the material base surface and
Dry to remove moisture. Then, 700-9
It is baked at a temperature of about 00 ° C. for about 2 to 10 minutes to print a picture pattern. And, as a result of printing, if there is a thin part in the color etc., if you want to make the color deeper, or if there is a part that you want to emphasize further, in those parts,
Apply emphasis processing. The emphasis processing is performed at 75/1000 to 25
This is performed by sprinkling a small amount of transparent or translucent cloisonne glaze with a granular color of about 0/1000 mm, or by applying an appropriate amount with a bamboo posse or a brush and baking.

And f. A transparent or translucent cloisonne glaze is applied to the entire surface by, for example, sprinkling and baking to form a vitreous finish layer (finish layer forming step). The glaze is desirably ground to a particle size of about 75/1000 to 250/1000 mm in order to obtain a uniform finish layer, and is preferably 700 to 900 ° C. until the glaze is completely welded.
Bake at a temperature of about 2 to 10 minutes.

The temperature and time in each step of the present invention are affected by the firing capacity of the firing furnace, the glaze used, the shape of the product, and the like, and are not limited to the above, but can be variously changed. .

By adopting such a configuration, it takes a long time to work as well as a long time for the work, and it is expensive, as in the conventional traditional techniques of wired cloisonne, wireless cloisonne, and transparent cloisonne. Compared to the conventional method, a large amount of products can be obtained in a short time, reliably, accurately, and inexpensively by a simple operation. In addition, traditional techniques such as wired wire enamel using silver wire had limitations in obtaining complex and delicate and precise patterns and subtle colors, but transfer paper that had been patterned and colored by printing was used. The use makes it possible to create complex, delicate and precise print patterns and those with subtle coloration. In addition, a large number of transfer papers having various patterns and colors are prepared in advance, and the necessary patterns and colors are immediately manufactured by selecting appropriate patterns and colors as needed from among them. Therefore, a wider variety of products can be supplied at any time than by the traditional techniques.

A silver-plated cloisonne ware, a metal plate that is baked by placing an embossed silver foil in close contact with a copper plate having an opaque base glaze and placing a colored cloisonne glaze on a desired portion of the die. Screen engraved with enamel glaze layer on which transfer paper is pasted and fired after enamel transfer, or screen engraved with enamel glaze layer after printing color pattern on screen printing plate and firing Compared with transfer baking, etc., the transfer layer provided with the glassy transparency, weight and elegance unique to Shippo Yaki products, and the subtle metallic light reflection of the silver layer and the transparent upper glaze layer A delicate, fine, dense and delicate multi-color print pattern intertwined with a three-dimensional effect produced by durable one that has a unique depth of luster and texture.

As a result of further printing, when there is a thin portion in the color or the like, when it is desired to give depth to the color, or when there is a portion to be further emphasized, an emphasis process is performed on those portions as necessary. In addition, it is possible to obtain a desired pattern and color, and it is possible to meet various demands of customers at any time by intentionally producing a slightly different one even with the same pattern.
