Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to ceramics that can prevent damage due to contact, etc., and a method for manufacturing the same.

[Conventional technology and its problems]

Traditionally, lacquerware or ceramics have been used as tableware.

+! ! In the case of I-porcelain, if multiple pieces of ceramic are stacked on top of each other for transportation or storage, each piece of ceramic may come into contact with each other and collide.
There is a problem that the edge of the ceramic is chipped or the surface of the ceramic is scratched. Also, when handling or using ceramics, please use l! ′! There is also the problem that porcelain pieces come into contact with each other and generate noise.

If you use lacquerware, the above-mentioned problems will not occur, but depending on the type of cooking or the situation, it may be necessary to use ceramics.

The present invention provides ceramics that are less prone to scratches due to contact, etc. and exhibits a new appearance, and a manufacturing method thereof. [Means for solving the problems] In order to achieve the above-mentioned objects, It is characterized in that the inner surface of the fabric is coated with a glaze finish, and the edges and outer surface of the fabric are coated with paint.

Furthermore, the method for manufacturing ceramics of the present invention is characterized in that after the inner surface of the cloth is glazed by firing, a paint is applied to the edges and outer surface of the cloth.

Examples of the above-mentioned paints include lacquer and synthetic resin paints. It is also desirable that the paint covers the entire edge of the ceramic.

〔Example〕

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, features of the present invention will be specifically described based on examples with reference to the drawings.

FIG. 1 is a cross-sectional view schematically showing a teacup according to the present invention.

In the figure, reference numeral 1 indicates the material of the tea bowl, and a coating of fired glaze 2 is formed on the inner surface of the tea bowl.

However, this coating is not formed on the edge Ia of the fabric 1.

The outer surface of the bowl is not coated with the glaze 2, but the lacquer is applied to the body 1b of the cloth 1 and the tube metal 1c.

A coating film of a predetermined thickness is formed using a paint 3 such as a synthetic resin paint. At this time, the upper edge of the paint 3 is the edge 1a of the fabric 1.
It is applied so that it goes beyond the glaze 2, slightly penetrates into the inner surface, and comes into contact with the edge of the glaze 2 on the inner surface.

When the paint 3 is applied on the glaze 2, the paint 3 is easily peeled off after drying, so the two should be prevented from overlapping.

Next, the method for manufacturing this tea bowl will be explained with reference to the process diagram in FIG.

First, form the dough 1 into the shape of a bowl, and
Bisque firing at 0-950°C for 8-16 hours.

Next, on the inner surface of the fabric 1, for example, 50 to 70% feldspar 1
Glaze 2 containing 10% limestone, 10-30% silica stone, and 5% kaolin is applied and heated at 1250-1350℃ for 12 to 30 minutes.
Bake for 24 hours. At this time, the outside is completely or partially dry-fired. That is, it is fired without applying glaze 2 to the outside. In addition, glaze 2 is applied to the edge 1a of fabric 1.
Avoid getting into the water.

Next, lacquer is applied to the dry fired part, that is, the outer surface of the dough 1.
Or paint 3 such as synthetic resin paint such as urethane or cashew
is applied to a predetermined thickness, for example, 0.01 to 0.2*m thickness. The color of paint 3 is vermilion.

Black, claws. Possible colors include green. At this time, the paint 3 is applied so as to go over the edge 1a of the fabric 1 and slightly penetrate into the inner surface. That is, the end of the glaze 2 and the end of the paint 3 are brought into contact with each other.

After that, under the conditions of 30-90% humidity and room temperature,
Let dry for 8 hours.

After the paint 3 dries, the tea bowl is completed by applying decorations by silk printing or the like as necessary.

Note that the bisque firing process can be omitted and the material can be directly fired, or a process of overlaying, such as red glaze, may be added after the firing process.

Figures 3 (A), (B), and (C) are plan views of the completed tea bowl.

A front view and a bottom view are shown.

According to the tea bowl manufactured in this way, the most broken
Since the edge 1a of the flexible fabric 1 is covered with the paint 3 of a predetermined thickness, even if the bowls come into contact with each other when stacked or arranged horizontally, the paint 3
acts as a buffer and prevents the bowl from being damaged. Moreover, since the paint 3 also acts as an elastic body, it is possible to suppress the generation of noise upon contact. Furthermore, paint 3
It also acts as an insulator, so when you hold the bowl, the heat from the contents does not transfer to your hands, and it also prevents heat radiation and has a heat-retaining effect.

In addition, in the above description, although the teacup was taken as an example, the present invention is not limited to this, and can be similarly applied to the teacup shown in FIG. 4. Furthermore, instead of covering the entire outer surface of the ceramic body with paint 3, the upper part of the body can be finished with paint and the lower part with glaze, as in the case of the coffee bowl shown in FIG. Furthermore, even if the edges are partially covered with paint, as in the case of the steaming bowl shown in FIG. 6 or the bowl shown in FIG. 7, some effect can be expected. At this time, as shown in Figure 7,
Depending on the pot, the lid can be divided into paint finish and glaze finish. Also, as shown in Fig. 8, fI+allhho7
．． , -++ 1, -r i, f-Kasugahiga;

Furthermore, although not shown, there are also Japanese cuisine tableware such as mukozuke.

It goes without saying that the present invention can also be applied to various types of ceramics such as a small 5-ten plate, a baking dish, a protrusion, a 5-sake sake bottle, a chintsuke, and a clay pot.

In addition, the method for producing ceramics according to the present invention is not limited to the process shown in Figure 2, but the simplest method is as shown in Figure 9, in which glaze is applied to the dough and directly fired. Paint may then be applied. At this time, the final firing may be performed after dyeing the fabric.

FIG. 10 shows another process diagram in which a painting process is added after the process shown in FIG. 9.

FIG. 11 shows yet another process in which the fabric is bisque fired, dyed if necessary, and then fired. Next, after overpainting such as red painting, paint is applied, and further painting is applied to the paint-applied area.

〔Effect of the invention〕

As described above, according to the present invention, the edges of ceramics that are most easily damaged are covered with paint of a predetermined thickness.

Therefore, even if ceramics come into contact with each other or with other objects, the paint acts as a buffer,
It can prevent damage to ceramics. Furthermore, since the paint also acts as an elastic body, it is possible to suppress the generation of noise upon contact.

In addition, the inner surface is glazed and the outer surface is lacquered, giving it a unique appearance not found in conventional tableware.

Hence, the gift! ! ! It is particularly suitable for items that require novelty, such as gifts and souvenirs. Furthermore, when used as a Japanese cuisine item or a household item, both the ancient traditional crafts of ceramics and lacquerware can harmonize and enhance the cuisine. In other words, it combines the coldness and weight of ceramic CI't and 2H with the soft texture of lacquerware.
