Description

  The present invention relates to pottery.

  In the production of pottery, to form a prototype of the required pottery from porcelain, if roughly divided, a method of forming a block of porcelain by hand using a kite, a string of a predetermined thickness is formed from the pottery clay In general, a method in which these are piled up in a spiral shape and then shaped is used, or a method such as stamping or pouring is generally used.

  As a craft pottery, any method is used, but the formwork is suitable for industrial production. On the other hand, the crafting of crafts for crafts requires a lot of skill to operate, so it is necessary for beginners. It is not suitable, and skill in molding is also required for a method of manually creating a thin string from ceramic clay and stacking it.

The following documents can be cited as technologies related to the production of pottery.
JP2005-35838. JP2003-327466A.

  In the above-described prior art, a skilled person uses a pot to form a desired molded product such as a vase or a vessel from porcelain, and from the beginning, it is molded by hand (by hand). Therefore, it is very difficult for beginners to obtain the desired molding.

  In particular, since the desired shape is formed from the porcelain mass, the size of the molding is limited by the original size of the porcelain mass, and it is necessary to make the porcelain mass large beforehand. Even if it is hand-kneaded, there is a limit, and how much size can be obtained with a large amount of porcelain clay can only be felt by an expert.

  The present invention is a pottery where even a beginner can easily create a pottery of a desired shape with a hand without using a basket, and can obtain a unique appearance when molding it. The purpose is to provide.

In order to achieve the above-mentioned purpose,
A pottery that performs unglazed baking and / or main baking after molding,
A measure is taken in which a plurality of porcelain granules having a particle size of 3 mm to 50 mm and a moisture content of 15% to 35% are interconnected to form.

Porcelain referred to in the present invention includes all soils generally used in pottery.
The granular material may not be a perfect sphere. Usually, it is created using a granulator, but it may be created manually.
The moisture content of 15% to 35% means having a viscosity capable of being connected (integrated) when the granular material is pressed.
Moreover, although a granular material is a round ball, the thing of a deformation | transformation spherical body close | similar to this is also contained.

  The porcelain clay particles having a particle size of 3 to 50 mm according to the present invention are used for the production of the ceramics.

According to the pottery according to the present invention, it is a simple task of stacking granular materials without using firewood, and by slightly deforming it by adding a slight hand twist, it is possible to create a pottery of the desired shape. It can be created easily.
And even though there are deformations due to the accumulation of granular materials and hand-bending, a part of the original granular material remains in the appearance, so that a pottery with a unique appearance can be manufactured.
In addition, according to the present invention, it is possible to obtain a desired molded article by granulating a granular material and stacking a large number of these, rather than using a ceramic clay block as a base. Even so, a desired molded product can be easily formed.

In carrying out the present invention, it is preferable to knead 10 to 20 parts by weight of sand having a particle size of 0.075 mm to 0.85 mm with respect to 100 parts by weight of the clay before the granulation.
The sand is sandstone that has been crushed, such as sand at the bottom of the sea that has the above-mentioned particle size, or sand that has been crushed by a crusher.
Thus, by kneading 10 to 20 parts by weight of sand (fine sand, medium sand) having a particle size of 0.075 mm to 0.85 mm , the viscosity of the porcelain clay can be lowered, and granulation can be facilitated.

Moreover, it is preferable to knead by mixing at least color clay prior to the granulation and simultaneously with or after the kneading of the porcelain clay and the sand.
In this way, by mixing color clay, it is possible to obtain granules of different colors, and if these are arbitrarily selected and stacked, the finished earthenware can be unglazed and generate color. Even without the glaze, it is possible to obtain a color pottery having a unique appearance or a partially different color.

Furthermore, it is preferable to perform granulation from the clay using a granulator.
The granulator referred to here may be any granulator generally used for granulating powder, and an appropriate one can be used.
Thus, if granulation is performed from porcelain using a granulator, a granule having a desired particle size can be easily obtained.

  A preferred embodiment of the pottery according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing a manufacturing process, FIG. 2 is a perspective view in which granular bodies are stacked and a vessel is formed, and FIG. 3 is a perspective view of the completed vessel.

Appropriate soil is used for the clay, such as cocoon, Bizen, Seto, and Iga. This porcelain clay is adjusted to contain 15% to 35% moisture and can adhere to itself as a mass.
15 parts by weight of sandstone powder of sand (fine sand, medium sand) having a particle size of 0.075 mm to 0.85 mm is mixed with 100 parts by weight of the clay and kneaded in a kneader.

Next, this clay is put into a granulator, and a large number of clay particles 1 having a particle diameter of 10 mm to 20 mm are granulated.
The porcelain granule 1 obtained in this manner is successively piled up into a circular shape as shown in FIG. At this time, pressure is applied by hand so as to be in close contact with each other while being compressed and deformed, and the container is molded as shown in FIG.

As shown in FIG. 3, the container has a deformed granular material 1 appearing on its appearance, and a container having a unique shape is formed.
Then, after drying, unbaking is performed, and then main baking is performed using glaze.

  Here, clay such as colored clay, gray, green, light brown, dark brown, pink, white, yellow, turquoise, sky blue, black, etc. are mixed in the clay and individually kneaded in a kneader. To do. In addition, knead with appropriate clay.

The obtained clay is mixed with 10 parts by weight of sandstone powder of sand (fine sand, medium sand) having a particle size of 0.075 mm to 0.85 mm with respect to 100 parts by weight of the clay and kneaded in a kneader. To do.
Then, a large number of 1 (2), 2 (3), and 3 (4) of 20 to 30 mm grain color ceramic clay particles are granulated by hand.

As shown in FIG. 4, the different color granules obtained in this manner are sequentially stacked around the mold 5 so that the desired color granules are located at the desired positions. At this time, when pressure is applied by hand so that they are in close contact with each other while being compressed and deformed, and the mold 5 is removed, as shown in FIG. 5, the inner surface in contact with the mold is flat, and the outer surface is made of granular material. A container with irregularities can be molded.
When the vessel thus obtained is dried and then subjected to unglazing, a vessel having a different appearance in appearance can be obtained. If necessary, apply an appropriate glaze to this unglazed grill and perform the main firing.

  Since the method for producing pottery and the porcelain granule according to the present invention are formed by stacking granulates, even a beginner can easily obtain a molded product of a desired shape, as a craft, It is also useful for industrial production.
