The hill is such that when a pottery container is placed on, for example, a table surface, its protruding surface is directly in contact with the table surface. Since the ground contact surface on the hill was grounded on the shelf plate during firing, the ground contact surface on the hill after firing was not covered with a material that was melt-sintered with glaze and vitrified.

[0003]

However, as described above, in the conventional pottery container, the ground contact surface on the hill formed on the outer bottom portion of the pottery container is covered with a glass material obtained by melting and sintering glaze. The ground surface on the hill is rough and not smooth. For this reason, when the pottery container is placed on, for example, a table surface, or the pottery container is dragged on the table surface, the table surface may be damaged by the ground contact surface on the hill of the pottery container. Therefore, in order to prevent this, a rough ground contact surface on the hill formed on the outer bottom of the manufactured pottery container is smoothed with a grinder or the like, but it is troublesome.

The present invention has been made in view of the above problems, and has been made in order to solve the problems. An object of the present invention is to separately manufacture a pottery container main body and a hill, and to provide a grounding device. The surface is coated with glaze, fired, melt-sintered, and the coated hill is bonded to the outer bottom of the pottery vessel body, and the glaze is melt-sintered on the ground surface of the hill that is bonded to the outer bottom of the pottery vessel. It is an object of the present invention to provide a pottery container hill which can prevent a table surface or the like from being scratched on a ground contact surface on the hill of the pottery container by coating with a vitrified material and making it smooth.

[0005]

Means for Solving the Problems In order to achieve the above object, according to the invention of claim 1, a porcelain formed on the outer bottom of a porcelain container is manufactured separately with a porcelain container body and a pedestal. The ground surface is coated with a glaze, fired, melt-sintered, and covered, and a hill is bonded to the outer bottom of the pottery container body.

In the figure, a pottery vessel 1 is composed of a pottery vessel main body 2 and a hill 3 which are manufactured separately, and the hill 3 is adhered to the outer bottom of the pottery vessel main body 2. In this embodiment, the entire surface of the inner surface and the outer surface of the pottery container main body 2 except for the grounding surface of the later-described bonding convex portion 2a is covered with the glaze 4 melted and sintered and vitrified. The surface is smooth due to vitrification and has gloss.

An adhesive projection 2a is formed, for example, in an annular shape on the main body bonding surface of the outside bottom of the pottery container main body 2 bonded to the hill 3. The bonding convex portion 2a is inserted into a bonding concave portion 3b of the hill 3 to be described later and engaged with the male and female. The adhesive projection 2a
It has a circular shape and other various annular shapes such as a triangle and a quadrangle, and has the same shape as the annular hill 3.

The adhesive projection 2a is used as a portion to be grounded on the shelf when the ceramic container body 2 is fired. Therefore, as described above, the glaze 4 does not adhere to the ground surface 2b of the bonding convex portion 2a.

The hill 3 is bonded to the outside bottom of the pottery container main body 2, and is formed in a circular shape or any other ring shape such as a triangle or a square. The hill is usually manufactured integrally with the pottery container main body, but in the present invention, the hill 3 is manufactured separately from the pottery container main body 2 and bonded after each firing.

An adhesive bonding surface 3a of the hill 3 which is bonded to the annular bonding convex portion 2a of the pottery container main body 2 has an annular bonding concave portion 3a.
b is formed. The bonding protrusion 2a and the bonding recess 3b engage with each other. The groove width of the adhesive concave portion 3b is slightly wider than the width of the adhesive convex portion 2a, so that the adhesive convex portion 2a is securely inserted into the adhesive concave portion 3b so as to be engaged with the male and female.

The ground surface 3c of the hill 3 is covered with the glaze 4 melted and sintered and vitrified, and the surface is smoothened by vitrification. The ground surface 3c of the hill 3 has, for example, a rounded convex cross-sectional shape. Therefore, the ground surface 3c of the hill 3 does not damage, for example, the table surface.

The hill 3 bonding surface 3a on which the bonding recess 3a is formed is used as a portion to be grounded on a shelf when the hill 3 is fired. Therefore, the hill 3 bonding surface 3a of the hill 3
Has no glaze 4 attached thereto.

The hill 3 is manufactured separately from the pottery container main body 2, and after each firing, it is bonded to the outer bottom of the pottery container main body 2 with an adhesive 5. The adhesive 5 is applied to the hill 3 bonding surface 3a. As the adhesive 5, for example, a standard high-performance epoxy-based strong adhesive (trade name “Araldide”) is used.

Next, a description will be given below of the manufacture of a hill for a pottery container based on the configuration of the embodiment of the present invention. First,
Fabrics for the pottery container main body 2 having an annular adhesive projection 2a formed on the outer bottom and an annular hill 3 having an annular adhesive recess 3b formed on an hill adhesive surface 3a are separately manufactured.

The pottery container main body 2 and the hill 3 are made by molding clay, for example, or cast into a mold. Further, the pottery container main body 2 and the hill 3 can be made using different doughs.
And the hill 3 can be made separately at a time or simultaneously.

After the dough for the pottery container main body 2 and the hill 3 is made, unglazing is performed. Unglazed, pottery container body 2 and hill 3
And in separate states. When performing unglazed,
The earthing surface 2b of the adhesive projection 2a of the pottery vessel main body 2 is grounded on the shelf, and the hill 3a of the hill 3 is grounded on the shelf.

After the unglazing, the pottery container main body 2
Glaze 4 is applied to the surface of. In this case, the grounding surface 2 of the adhesive projection 2a of the pottery container main body 2 that is grounded on the shelf plate in the final firing
A water repellent or the like is applied in advance to the ground surface 2b of the adhesive projection 2a so that the glaze 4 does not adhere to the b.

Similarly, the glaze 4 is applied to the ground surface 3c of the hill 3. In this case, the hill 3 that touches the ground on the shelf
In order to prevent the glaze 4 from adhering to the hill-adhering surface 3a, a water-repellent agent or the like is applied to the hill-adhering surface 3a in advance. This water repellent has a function of preventing the glaze 4 from adhering.

After the glaze 4 is applied to the surface of the pottery container main body 2 and the ground surface 3c of the hill 3, respectively, the main firing is performed.
The baking is performed in a separate state in which the pottery container main body 2 and the hill 3 are separated from each other. When performing the main baking, the grounding surface 2b of the bonding projection 2a of the pottery container main body 2 is grounded on the shelf board, and the hilltop bonding surface 3a of the hill 3 is grounded on the shelf board.

During the baking, the glaze 4 applied to the ground surface 3c of the hill 3 is melted, vitrified and sintered. As a result, the ground surface 3c of the hill 3 is covered with the glass obtained by melting and sintering the glaze 4, and the surface becomes smooth.

After the baking, an adhesive 5 is applied to the elevated bonding surface 3a of the elevated platform 3, and an adhesive projection formed on the outer bottom of the pottery container main body 2 is formed in the adhesive concave portion 3b formed on the elevated bonding surface 3a of the elevated platform 3. The hill 3 is adhered to the outer bottom of the pottery container main body 2 with the adhesive 5 so that the pottery 2a is inserted, and the manufacture of the pottery container 1 is completed.

It should be noted that the present invention is not limited to the above embodiment of the present invention, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the case where the glaze 4 is applied to the surface of the pottery container main body 2 has been described, but may be omitted as necessary.

[0025]

As is apparent from the above description, according to the terrain of the pottery container according to the first and second aspects of the present invention, the ground surface of the hill formed on the outer bottom of the pottery container is formed by melting and burning the glaze. Even if the pottery container is placed on the table surface or the pottery container is dragged on the table surface, the table surface is placed on the ground contact surface on the plateau of the pottery container because it is covered with vitrified and vitrified and smooth. Will not hurt.

Since the hill and the pottery container main body are separately manufactured, the shape of the hill can be any desired shape such as a triangle, a quadrangle, a polygon, etc. other than a generally used circular shape. Thus, the appearance of the pottery container can be enhanced.

According to the second aspect of the present invention, in addition to the above effects, in addition to the above effects, an adhesive projection is formed on the outer bottom portion of the main body of the ceramics container, and an adhesive concave portion is formed on the adhesive surface of the elevated plateau. By forming and bonding the bonding projection and the bonding recess to each other, the platform can be more securely bonded to a predetermined bonding position on the outer bottom of the pottery container body without shifting the platform during bonding. Moreover, the adhesive projection formed on the outer bottom of the pottery container main body can be used as a ground surface when the pottery container main body is placed on the shelf plate during firing.
