The Joeunchina Jangsing dojagi jejobeop {The Joeunchina Jangsing dojagi jejobeop}

The present invention relates to a method of making decorative ceramic articles, and more particularly, to a method of manufacturing decorative ceramics made by inserting a selected ornament into a ceramic product.

There has been an endless effort in the field of ceramic technology or ceramics to find new and desirable decorative effects and ways to create them.

From a consumer's point of view, a desirable decorative effect of a ceramic product can be obtained when an ornament that interests the consumer appears as a three-dimensional component on the outer surface of the ceramic. This is strictly distinguished from simply two-dimensional surface decoration.

The decoration of porcelain products has generally been limited to decoration in a two-dimensional form on the surface of the porcelain, and the three-dimensional decoration of the porcelain product is a composite porcelain product in which glass is coated on the surface of the porcelain product, and a thin surface glass. It has been made in the form of covering three-dimensional objects with glass. However, the latter method has a problem that the ornaments wrapped with the glass film on the surface do not match with the surrounding glass and ceramics.

The present invention was conceived in view of the above problems, and an object of the present invention is to provide a method of manufacturing decorative ceramics in which ornaments appear three-dimensionally on the surface.

The manufacturing method of decorative ceramics of the present invention for achieving the above object comprises the steps of (a) forming and drying a ceramic product from ceramic clay; (B) forming a central hole in the wall of the ceramic product according to the size of the selected decorative rock; (D) placing decorative rocks in the central hall formed in step (b) and filling the surroundings with clay; (E) drying the ceramic product; And in the manufacturing method of decorative ceramics including the step (f) of baking the porcelain product, the step of forming a shrinkage buffer means on the wall of the porcelain product around the central hole formed in step (b) before the step (d). It characterized in that it includes (c).

The manufacturing method of decorative ceramics of the present invention also includes the steps of (a) forming and drying a ceramic product from ceramic clay; (B) forming a central hole in the wall 6 of the porcelain product according to the size of the selected decorative rock; (E) drying the ceramic product; And in the manufacturing method of decorative ceramics including the step (f) of baking the porcelain product, the central hole formed in the step (b) is formed in the form of a plate groove with a size that allows rock to enter it It is characterized in that, while keeping the rock in place, the hollow space around it is filled with a filling of a mixture of clay and emulsion, which is a means of buffering contraction.

As described above, in the method for manufacturing decorative ceramics according to the present invention, selected rocks are stably embedded in order to manufacture ceramic products decorated with selected rocks such as volcanic rock, and rupture due to shrinkage of ceramic clay is suppressed during the manufacturing process of ceramics. By allowing them to have a desirable decorative effect and attract consumers' attention, e.g. volcanic rocks such as basalt can appear three-dimensionally on the outer surface of ceramics, and thus a desirable decoration that is much more attractive than conventional ceramics and gives a new aesthetic. You will be able to have an enemy effect.

The decorative ceramic products of the present invention can be variously appeared in forms mainly related to ceramic technology. That is, there may be vases, jars, tiles, cups, and other items made from clay and glaze.

The manufacturing method of the present invention was devised to suppress the rupture of pottery due to shrinkage of pottery clay during drying or baking while the selected rock maintains a stable position.

The rock does not cause any shrinkage, but the method of drying with air causes the shrinkage of about 12% of the pottery clay, and baking with fire causes the shrinkage of about 1~2% of the pottery clay.

The step (a) of forming and drying a ceramic product from ceramic clay is performed by a conventional method. In step (a), drying is carried out for a day or two at ambient temperature.

The step (b) of forming the central hole 5 and 5A, which is the hole in which the selected rock is to be seated, can be performed in several ways. As shown in FIGS. 1 to 4, 7 and 8, the central hole 5 may be formed in the form of a through hole, and as shown in FIGS. 5 and 6, the central hole 5A is slightly dug. It can be formed into a shape.

In one embodiment, using the rock 4 as a guide, the rock 4 is placed on the surface of the dried pottery, and the cutting line is marked, and the wall of the pottery is cut along the cutting line marked with a tool such as a knife. A central hole (5) to be embedded is formed.

The edge around the central hole 5 is preferably formed as a tapered edge 7 having a vertex contacting the surface of the rock 4 at an angle of about 45°C, as shown in FIGS. 2, 4 and 8 . If the apex of the tapered edge 7 is thin, it helps to suppress the contraction of the wall 6. In another embodiment, as shown in FIG. 6, the central hole 5A is formed in the form of a groove that is not penetrated and is dug.

Such a groove-shaped central hole 5A can be made by simply pushing by hand or pressing rock without cutting the porcelain wall 6 before the porcelain is completely dried. Using a rock having a size larger than that of the rock 4, press the wall 6 so that the rock 4 enters, to form the central hole 5A, and then remove it.

In the step (c) of forming the shrinkage buffering means on the wall 6 of the porcelain product around the central hole 5 and 5A formed in step (b), the shrinkage buffering means is dried and dried in preparation for shrinkage of the ceramics. It is made to prevent rupture of ceramics during the baking process.

The shrink cushioning means can be made in various forms.

As an example, as shown in FIGS. 1 and 2, a plurality of small peripheral holes 3 may be formed around the central hole 5 in which the rock 4 is to be placed.

As another example, as shown in FIGS. 3 and 4, a groove-shaped annular groove 8 may be formed in the porcelain wall 6 around the central hole 5. The annular groove 8 is preferably made to a depth of about 75 to 85%, preferably about 80% of the clay wall 6.

The thinner deeper grooves are, the less effective they are at preventing rupture of the pottery when drying or baking. The deeper the groove, the weaker the ceramic wall. In consideration of this, it is preferable to set the depth of the annular groove 8 to about 80% of the thickness of the wall 6 as described above.

As such, a plurality of peripheral holes 3 and annular grooves 8 may be used as the shrinkage buffer means, and the cross-sectional area may be in various shapes having a circular, triangular, rectangular shape, and the like.

5 and 6, when the central hole 5A in which the rock 4 is to be placed is in the form of a groove, the contraction buffer means is used to keep the rock 4 in its position and It is a filling of clay and latex mixture that fills the aftershock space. In that case, first, the ceramic products are dried and filled. For example, the ceramics are dried for about 10 days or 2 weeks under atmospheric conditions, and then partially filled with moist clay and latex in the hollow center hole (5A).

The mixture of latex and clay acts as an adhesive to hold the rock 4 in place and as a shrinkage buffer to prevent rupture of the ceramic wall during the subsequent drying and baking process.

When the central hole 5 is in the form of a through hole, when placing the rock 4 in the central hole 5 of partially dried ceramics, it is better to soak the rock 4 in water in advance to wet it.

If the central hole 5A has a groove shape, it is better to coat the bottom of the rock 4 with a mixture of clay and emulsion before putting the rock 4 in the central hole 5A. The empty space remaining in the central hall 5A is filled with an additional clay and emulsion mixture.

Then, the ceramic products are dried and baked for about two weeks in the traditional way at room temperature. After that, the above-described central hole 5 (5A), peripheral hole 3 or annular groove 8 is filled with a mixture of moist clay and emulsion.

The mixture of clay and emulsion has a lower softening point than clay, and acts as a buffer against rupture of ceramics.

The composition of the clay and emulsion mixture is generally between about 40/60 and 60/40, with 50/50 being most preferred. It is a good idea to dry the ceramic product before proceeding to the next step each time you fill the clay and latex mixture.

Then, the porcelain product was dried again, baked at 08 cone temperature for about 12 hours and cooled for about 12 hours.

More preferably the porcelain product is then coated with an emulsion. For example, dip it in latex, dry again and bake. At this time, bake about 12 hours at 05 cone temperature.

[Example 1]

Porcelain vases were made from stoneware clay by traditional methods using a pottery wheel. The vase was dried for about 24 hours at room temperature. Jeju volcanic rock was selected as a decoration, and the center hole 5 was formed by cutting it into size enough to put the volcanic rock on the wall of the vase. The edge of the central hole was thinly cut with a tapered edge (approximately 45 degrees) to suppress shrinkage during the subsequent drying process. In addition, several small peripheral holes were drilled in the wall of the vase around the central hall as a means of buffering shrinkage in order to prevent rupture of the ceramics during drying and baking. The volcanic rock was soaked in water and inserted into the central hall. The vase was then dried at room temperature for about two weeks, and then filled with a 50/50 mixture of transparent emulsion GG-1700 and stoneware clay NO.153 (powder clay) in a small peripheral hole around the rock.

All. After drying for 24 hours, the surrounding hole was refilled with a mixture of 50/50 clay and emulsion, and the vase was dried again at room temperature for 1-2 days. The vase was then baked at O8 cone temperature (1737°F) for 12 hours and then cooled for 12 hours. A mixture of clay and latex filled the space between the rock (4) and ceramics. After being put in an emulsion container, it was taken out, dried for 1-2 days, baked at 05 cone temperature (1891°F) for 12 hours, and cooled for 12 hours.
