Method of making decorative ceramic article

The present invention relates to a method of making decorative ceramic articles (ceramic articles), and more particularly to a method of manufacturing a decorative ceramics made by embedding any selected decoration in the ceramic products.

Efforts have been constantly made to find new and desirable decorative effects and methods for creating such effects in ceramic technology or ceramics.

From the consumer's point of view, the desired decorative effect of the porcelain product can be obtained when an ornament of consumer interest appears as a three-dimensional component on the exterior surface of the porcelain. It is simply distinguished from the two-dimensional surface decoration.

For example, some tourists who visited the area where the volcanic activity existed (Jeju) would find the decorative pottery much more fascinating as a souvenir if they were made to see a piece of basalt produced by volcanic activity.

However, the physical properties of basalt differ from the physical properties of the materials used to make ceramic products, so combining objects such as basalt as a component of ceramic products is difficult and incompatible with and incompatible with ceramic manufacturing requirements.

As an example, basalts, objects mixed in ceramic clay, can be loosened and separated from ceramic products, or broken by shrinking ceramics during the drying and baking process.

For this reason, the decoration of ceramic products has generally been limited to decorating two-dimensional forms on the surface of ceramics, and the third representation of the ornaments is a thin type of composite ceramic products in which glass is coated on the surface of ceramic products. It has been made to cover a three-dimensional object with glass inside the surface glass. The latter method, however, has the problem that the ornaments covered by the glass membrane on the surface do not match the surrounding glass and ceramics.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a method of manufacturing a decorative ceramics ornaments appear three-dimensionally on its surface.

Decorative ceramic products of the present invention may appear in various forms mainly related to ceramic technology. There may be vases, jars, tiles, cups, and other items made of baked clay and glaze.

The manufacturing method of the present invention is designed to suppress the rupture of the porcelain due to shrinkage of the porcelain clay during the drying or baking process while the selected rock is maintained in a stable position.

Rocks do not cause any shrinkage, but air drying results in about 12% shrinkage of porcelain clay, and burning fires about 1-2% shrinkage of porcelain clay.

The step (a) of forming and drying the porcelain product from porcelain clay is carried out by conventional methods. In step (a), drying is carried out for one or two days at ambient temperature.

The step (b) of forming the central holes 5 and 5A, which are holes to which the selected rock is to be seated, can be carried out in various 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 groove in which the central hole 5A is slightly recessed. It can be formed in the form.

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

The edges around the central hole 5 are preferably formed as tapered edges 7 having a vertex angle of about 45 ° C. in contact with the surface of the rock 4 as shown in FIGS. 2, 4 and 8. . The thinning of the vertex of the tapered edge 7 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 which is not penetrated and is excavated.

This groove-shaped central hole 5A may be made by simply pushing by hand or pressing rock without cutting the ceramic wall 6 before the ceramic is completely dried. The foil is removed using a rock of a size larger than that of the rock 4 to press the wall 6 so that the rock 4 is enough to enter and form the central hole 5A.

In the step (c) of forming the shrinkage buffer means in the wall 6 of the porcelain product around the central hole 5, 5A formed in the step (b), the shrinkage buffer means is dried and prepared for shrinkage of the porcelain. It is made to prevent pottery rupture during the burning process.

Shrinkage buffers can be made in a variety of forms.

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

As another example, as shown in FIGS. 3 and 4, an annular groove 8 in the form of a groove may be formed in the porcelain wall 6 around the central hole 5. The annular groove 8 is preferably provided to a depth of about 75 to 85%, preferably about 80%, of the clay wall 6. Thinner grooves are less effective at preventing ceramic rupture when drying or baking. Deep grooves weaken the walls of ceramics. In view of this, as described above, the depth of the annular groove 8 may be about 80% of the thickness of the wall 6.

As described above, a plurality of peripheral holes 3 and annular grooves 8 may be used as the cushioning means, and the cross sectional area may be in various forms having a circular, triangular, rectangular, or the like shape.

As shown in Figs. 5 and 6, when the central hole 5A on which the rock 4 is to be placed is in the form of a groove, the contraction buffer means keeps the rock 4 in place to hold the wave around it. A filling of clay and latex mixture that fills the aftershock space. In this case, the porcelain product is first dried and filled. For example, the porcelain is dried for about 10 days or two weeks under atmospheric conditions and partially filled with moist clay and emulsion in the dug hole (5A).

The mixture of latex and clay serves as an adhesive to hold the rock 4 in place and as a shrink buffer to prevent rupture of the porcelain wall during subsequent drying and baking processes.

When the central hole 5 is in the form of a through hole, when the rock 4 is positioned in the central hole 5 of the partially dried pottery, it is preferable to soak the rock 4 in water in advance.

If the central hole 5A is in the form of a groove, it is preferable to coat the bottom surface of the rock 4 with a mixture of clay and emulsion before the rock 4 is placed in the central hole 5A. The empty space remaining in the central hole 5A is filled with additional clay and emulsion mixture.

Pottery products are then dried and baked for two weeks at room temperature using traditional methods. Thereafter, the above-mentioned 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 latex has a lower softening point than clay and acts as a buffer against rupture of ceramics.

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

The ceramic product is then dried again, baked at 08 cone temperature for about 12 hours and cooled for about 12 hours.

More preferably the ceramic product is then coated with latex. For example, soak in latex, dry and bake again. Bake about 12 hours at 05 cone temperature.

Example 1

Porcelain vases were made of stone clay using traditional ceramic spinning wheels. The vase was dried at room temperature for about 24 hours. As a decoration, volcanic rocks of Jeju were selected and cut to a size enough to put volcanic rocks on the walls of the vase to form a central hole 5.

The central hole edge was thinly cut into tapered edges (approximately 45 ° angle) to suppress shrinkage during the subsequent drying process. In order to prevent the rupture of the ceramic during drying and baking process, several small peripheral holes were drilled in the wall of the vase around the central hall as a shrink buffer.

Volcanic rocks were soaked in water and inserted into the concourse. The vase was then dried for about two weeks at room temperature and then filled with a mixture of 50/50 of transparent latex GG-1700 and stone clay NO.153 (powder clay) in a small perimeter around the rock.

After drying for 24 hours, the surrounding holes were refilled with a mixture of 50/50 clay and latex, and the vase was dried again for 1 to 2 days at room temperature. The vase was then baked for 12 hours at O8 cone temperature (1737 ° F) and then cooled for 12 hours.

A mixture of clay and latex filled the space between rock (4) and pottery. The solution was placed in an emulsion container, taken out, dried for 1-2 days, baked at 05 cone temperature (1891 ° F.) for 12 hours and cooled for 12 hours.

Example 2

Following the general process of Example 1, the shape of the porcelain vase was formed, partially dried, and a groove-shaped central hole was formed to fit the selected volcanic rock on the wall of the vase. The periphery of the groove in which the rock will be placed is largely rounded to fill the cushioning means later.

The grooves were formed to a depth of 80% of the thickness of the porcelain wall. The selected rocks were soaked in water and placed in the grooves and the ceramic vase was dried for 2 weeks. The grooves were filled with a mixture of moist clay and emulsion (about 50/50 mixture) and dried for about 24 hours.

The process of filling the grooves with a mixture of clay and emulsion and drying was repeated twice, filling the grooves and creating a smooth surface. The ceramic vase was baked at 08 cone temperature for 12 hours and then cooled for 12 hours. The vase was then lacquered in the traditional way and baked and cooled for 6 hours at 05 cone temperature.

Example 3

The ceramic vase was shaped from stone clay and partially dried at room temperature for about 36 hours. Decorative volcanic rocks were selected and a portion of the partially dried vase was pushed to form a grooved hole. The rock was then removed and the ceramic vase dried at room temperature for about two weeks.

The dug grooves are then coated with a mixture of 50/50 moist clay and emulsion. The rock is then placed in a hollow grooved hole, and the empty space is filled with a mixture of additional clay and latex. The porcelain vase was then dried, baked, latexed and baked again as in Example 1.
