Description

Description: FIELD OF THE INVENTION The present invention relates to a method for producing a patterned ceramic product. In particular, it is a technique of a manufacturing method of a ceramic porcelain in which a pattern can be applied to the surface, the back surface, the inner surface, and the hard-to-reach places of the product.

(Prior art) The conventional manufacturing method of ceramics with a picture pattern is to put the clay in a plaster mold, turn it with a potter's wheel to make a dough, and heat it at 900-1000 ° C.
Do unglazed at about the temperature, manually paint it with a glaze, put it in a kiln and bake at a temperature of about 1200 ~ 1300 ℃,
It is a method of making ceramic products with pictures.

There is also a method in which, instead of manually painting, a transfer paper is attached to the surface of the clay after modeling and then unglazed, and then a glaze is applied and baked at a temperature of 1200 to 1300 ° C.

(Problems to be Solved by the Invention) In the conventional manufacturing method of the painted ceramics by the manual painting, the manufacturing cost is high because it is a manual work, and the manufacturing method is not suitable for mass production. In addition, the manual painting on the inner surface and the back surface of the product further increases the manufacturing cost. In addition, painting on the handle, the spout, and the inner surface of a complicated shape was time-consuming and time-consuming.

Further, in the conventional manufacturing method using transfer paper, the transfer paper is attached to the shape of a product such as tableware after modeling, so the transfer paper has to be attached to the curved portion after modeling, which is also time-consuming and container-shaped. It was difficult to attach the product to the inner surface of the product or to a place with a complicated shape.

The object of the present invention is to solve the above-mentioned problems of the prior art, and to easily paint even on the back surface, the inner surface, and the part of a complicated shape of the product, and moreover, it is possible to easily manufacture the ceramics with a pictorial pattern with good manufacturing efficiency. To provide a manufacturing method of.

(Means for Solving the Problems) The gist of the present invention which has solved the above problems is as follows: 1) Clay clay is flatly spread to form a thin plate, and a transfer paper having a pattern is attached to the surface of the clay plate, and then the clay Deform or cut and paste thin plates into the shape of the required products such as tableware, unglazed after shaping, and then apply glaze and fire to manufacture a ceramic product with a picture pattern 2) Ceramic thin plate The method of manufacturing a ceramic according to claim 1, wherein a transfer paper with a picture pattern is adhered to the entire front surface and the back surface. 3) The transfer paper with a picture pattern is adhered only to a part of the surface of the clay thin plate. 4) Method for manufacturing ceramics 4) The method for manufacturing ceramics according to any one of claims 1 to 3, wherein the transfer paper is a copper plate transfer paper.

(Operation) In the present invention, the clay is flatly spread to form a thin plate, and a transfer paper having a desired pattern is attached to the upper surface and / or the lower surface (rear surface) or a part of the surface.

After that, the ceramic clay thin plate to which the transfer paper is attached is bent, deformed, or cut and pasted to form a desired product shape. The transfer paper can be attached to the surface of the molded clay article, such as the front surface, the inner surface, the bottom surface, the back surface, the handle, and the sprinkle intricate parts.

Next, the shaped clay to which the transfer paper is attached is unglazed, coated with glaze, and fired at a high temperature to manufacture a ceramic product with a picture pattern.

(Example) Hereinafter, an example of a method for manufacturing a cup will be described.

First, a ceramic clay thin plate (1) obtained by extending the ceramic clay into a rectangular shape with a thickness of about 3 mm, a ceramic clay thin plate (2) as a handle portion, and a circular ceramic clay thin plate (3) as a bottom portion are made. Next, copper plate transfer papers (4), (5) and (6) having a required picture pattern are attached to the respective top surfaces and bottom surfaces of the ceramic clay thin plates (1), (2) and (3). Cut a thin plate (2) of ceramic earth, which will be a handle part, to which the transfer paper is attached, with a predetermined width. Next, the clay thin plate (1) is rolled into a cylindrical shape, and the clay portions at both ends are connected. A circular ceramic clay thin plate (3) is connected to the bottom of the cylindrical ceramic clay. Further, the ceramic clay thin plate (2) having a short width cut on the side surface of the cylindrical ceramic clay thin plate (1) is deformed into an ear shape, and then attached as a handle. In this way, after shaping into a cup shape, unglazed, applying glaze and baking at high temperature
A cup with a picture pattern on the back and handle can be manufactured.

In addition, in the present invention, it is needless to say that, in addition to modeling with only the clay thin plate to which the transfer paper is attached, other shapes such as stick-shaped clay, clay clay without transfer paper, and clay clay material can be combined as required. . The thickness of the clay thin plate is usually 1 to 5 mm.

(Effect of the invention) As described above, according to the present invention, the transfer paper is attached to the ceramic clay thin plate before being molded, and then deformed and cut and molded, so that it is possible to draw on the inner surface, the back surface, and the complicated shape part of the product. Can be patterned. Moreover, since the transfer paper is attached to the ceramic clay thin plate, the work of attaching the transfer paper can be performed very easily and quickly.
