[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of decorating pottery such as tiles by forming an uneven pattern on the surface thereof.

0002

[Prior Art] Traditionally, decorations have been applied to the surfaces of tiles, etc., especially when it is desired to form an uneven pattern on the surface.
Before baking, it was necessary to appropriately form raised portions and the like that would form an uneven pattern on the surface.

0003

[Problems to be Solved by the Invention] However, appropriately forming raised portions on the surface in order to obtain a concave-convex pattern has the problem that it requires labor and reduces productivity.

0004

[Means for Solving the Problems] The present invention was devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a method for decorating ceramics that can easily form an uneven pattern on the surface. The gist of this is to form predetermined block-shaped chips with glaze particles, place the chips at predetermined intervals on the surface of unglazed pottery or unfired pottery base, and bake them at a predetermined temperature. The process involves melting and forming an uneven pattern on the surface.

[0005]

[Operation] Using a chip formed into a predetermined shape with glaze, this chip can be baked at a predetermined temperature and melted to create an uneven pattern.There is no need to form an uneven pattern on the pottery itself in advance, and a good uneven pattern can be created. can do.

[0006]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. When forming a hemispherical uneven pattern on the surface of a tile, a cylindrical chip 1 as shown in FIG. 1 is shaped in advance. This chip 1 contains 34.5% by weight of feldspar and 1% by weight of silica.
3% by weight, clay 5.8% by weight, calcium carbonate 15.3%
It has a composition of 1.0% by weight of alumina, 27.4% by weight of frit, and 14.7% by weight of pigment, and has the composition as a general ceramic glaze. The glaze is first dried, then finely crushed and sieved using a 60-mesh sieve, and the resulting glaze particles are compacted using a press or the like under a pressure of about 1 ton to form the block-shaped chips shown in Figure 1. 1.

The chip 1 has a diameter of 10 mm, as shown in a plan view in FIG. 2, and a height of 2.5 mm, as shown in a side view in FIG. A large number of such chips 1 are prepared, and a glaze 3 is first applied to the surface of an unglazed tile 2 as shown in FIG. This unglazed tile 2 is formed into a plate shape with a size of 197.8 mm x 28 mm and a thickness of 6 mm, and is unglazed from a base made of 50% by weight of Rouseki, 40% by weight of clay, and 10% by weight of lime. . The glaze 3 applied to the surface contains 26% by weight of feldspar, 15% by weight of zinc white, and 12% by weight of silica.
Weight %, clay 14 weight %, frit 25 weight %, pigment 8
It consists of a composition of % by weight.

Further, as shown in FIG. 5, the chips 1 were arranged in a row at predetermined intervals on the surface of the glaze 3 with glue 4 interposed therebetween, and the interval between each chip was 40 mm. In addition, unglazed tile 2
If screen printing is used to place the chips 1, 1, 1 in multiple rows on top of the tile 2
Chips 1, 1, 1 can be arranged in a row on top. or,
If you print glue 4 in advance on the area where the screen print chips 1, 1, 1 will be placed, you can also print the chips 1, 1, 1,
1 can be easily installed in a row.

[0009] With the glaze 3 applied on the unglazed tile 2 and a plurality of chips 1, 1, 1 placed on the surface at predetermined intervals, the glaze 3 is heated in a roller hearth kiln.
When baked at 10° C. for about 20 minutes, the chips 1, 1, 1 melt and weld together with the glaze 3 to the surface of the unglazed tile 2, as shown in a side view in FIG. 6 and in a plan view in FIG. After firing, each chip 1, 1, 1 becomes a semicircular pattern body 1A, 1A, and becomes integral with the unglazed tile 2.

In this example, the diameter of each pattern body 1A is 1
1 mm, and a height of 2 mm was obtained, indicating that a good uneven pattern was formed by the plurality of pattern bodies 1A, 1A, 1A.

[0011] In this example, the patterns 1A, 1A, 1A have a glossy black color, and the glaze 3 has a matte black color, so the surface of the tile 2 has a matte black surface and its surface. A glossy uneven pattern was obtained. If the composition of the glaze 3 and the chip 1 are the same, it is possible to form an uneven pattern of the same quality and color on the surface of the unglazed tile 2. Furthermore, by changing the composition of the glaze 3 and the chip 1, especially the color By changing the pattern bodies 1A, 1A, it is possible to appropriately change the patterns 1A, 1A, and by changing the color of each chip arranged in a row, it is also possible to obtain a concavo-convex pattern with a different color. Moreover, the unglazed tile 2
may be a tile base before firing.

In this example, the chip 1 is formed into a cylindrical shape,
Although a hemispherical pattern 1A was obtained from this chip 1, the shape of the pattern 1A can be changed by changing the shape of the chip 1. Further, by appropriately adjusting the firing temperature, time, etc., the shape, unevenness height, etc. of the pattern body 1A can be adjusted.

[0013]

[Effects of the Invention] The ceramic decoration method of the present invention involves forming predetermined block-shaped chips using glaze particles, and placing the chips at predetermined intervals on the surface of unglazed pottery or a pottery base before firing. By baking at a predetermined temperature and melting the chips to form an uneven pattern on the surface, if you prepare a large number of chips with a predetermined shape, you can melt the chips and create a good unevenness on the surface of ceramics such as tiles. It has the effect of forming a pattern, making it easy to adjust the shape of the uneven pattern, etc., and extremely improving the workability of forming the uneven pattern.
