Description

The present invention relates to an auxiliary tool for producing a plate-shaped ceramic with a grain pattern, and more specifically, when producing a plate-shaped ceramic with a grain pattern, anyone can easily create a plate-shaped ceramic with a grain pattern without requiring skill. It is a technique related to an auxiliary tool that can be suitably used for producing a plate-shaped ceramic with a grain pattern that can be expressed.

Pottery and porcelain are collectively called porcelain as earthen products that are semi-permanently hardened by firing in a kiln, etc. The type and properties can be changed in various ways depending on the firing method and the glaze.

The details of the pottery production method are described in, for example, Patent Document 1 (the name of the invention "ceramic tableware"), but especially for the patterning such as the grain pattern applied to the pottery. It is often done in the middle of the production process, and it is said that it is difficult for beginners because it requires advanced skills and knowledge, as well as skill and experience.

On the other hand, in Patent Document 2 (the name of the invention "ceramic product with wood grain pattern and its manufacturing method"), clay prepared in a predetermined composition is developed into a thin plate on a flat substrate and rolled up from a small edge to form a cylindrical body. There is a description that the surface (cut surface) of the grain pattern can be obtained by forming the above and cutting along the diameter of the cylinder.

According to the conventional method including the disclosure techniques of Patent Document 1 and Patent Document 2, the patterning including the grain pattern applied to the ceramic is often performed in the middle of the production process, and in addition to the advanced technique and knowledge, Since skill and experience are also required, there is a problem that it is difficult for beginners, and a method for producing ceramics with a grain pattern that anyone can easily express without skill has been sought.

Moreover, in the production of ceramics with a grain pattern, as shown in FIG. 2 of Patent Document 2, clay is spread on a flat surface, pigment powder is sprayed on the upper surface thereof, and then the cylinder is rolled up from the edge. Since it is formed and cut along the radial direction of the cylinder as shown in FIG. 5 of Patent Document 2, an orderly grain pattern is expressed on the cut surface within the radius of the cylinder. As a result, there was also the inconvenience that it was not possible to produce a preferable grain pattern, although it exceeded the radius of the cylinder.

The present invention was made in view of the above-mentioned problems seen in the prior art, and anyone can easily express the grain pattern on the produced product itself without requiring skill, and the surface size is relatively wide. It is an object of the present invention to provide an auxiliary tool for making a plate-shaped pottery with a grain pattern, which can produce a plate-shaped pottery with a grain pattern.

The present invention has been made to achieve the above object, and is separately arranged with a base plate having a trapezoidal shape in a plan view and guide grooves facing each other on two opposite sides of the base plate. The base is formed by cutting the pair of guide plates and the guide groove mutual direction of the plate material having a plan-viewing rectangular shape that can freely slide through the guide grooves. The one-side trapezoidal support plate and the other-side trapezoidal support plate are alternately arranged on the plate so as to face each other, and along the long-bottomed edge of each of the one-side trapezoidal support plate and the other-side trapezoidal support plate. Each of the two columns, which are vertically arranged via a pair of insertion holes arranged side by side through a gap having the same width, and the one-side trapezoidal support plate and the other side when face-to-face are arranged. One located in the vicinity of each short bottom edge of the trapezoidal support plate in the direction orthogonal to the short bottom edge and near the short bottom edge is arranged side by side with the insertion hole on the row side, and the other is inside the insertion hole. Two columns each erected through a pair of insertion holes arranged vertically through a space having the same width as the space, and a variable square space area surrounded by these eight columns. The long rectangular side plate and the short rectangular side plate that are freely arranged vertically, and the one-side trapezoidal support plate and the other-side trapezoidal support in the square space area can be freely accommodated to the variable surface size of the square space area. The variable surface size of the square space area is composed of at least a bottom plate that covers the bottom side including a plate, and two types of clay for making ceramics prepared with different colors are alternately laminated and arranged at a constant thickness. The most important feature is that one of the trapezoidal support plate on one side and the trapezoidal support plate on the other side, which is located on the operation side, can be expanded and contracted by moving along the guide groove.

In this case, a stopper whose top surface height matches that of the guide plate is arranged on either side of the two opposing sides of the base plate that does not have the guide plate, and the one-side trapezoidal support plate and the said. It is desirable that one of the trapezoidal support plates on the other side can be freely placed on the non-operation side.
