Abstract

PURPOSE:To allow a pattern to appear or disappear according to the striking state of light, and to improve decorative properties by forming transparent glass glaze on the surface of the layer of crystallite mat glaze at points or in lines or in a partial surface shape and constituting a glaze layer. CONSTITUTION:A title 1, in which a glaze layer 3 formed to a tile foundation 2 is composed of a layer 4 of crystallite mat glaze and transparent glass glaze 5 having the same color as the mat glaze, in which a pattern such as a design, characters, symbols, etc., is formed on the surface of the layer 4 of the mat glaze at points, in lines or in a partial surface shape, is formed. The layer 4 of the mat glaze forms a delustered surface having inferior gloss while the transparent glass glaze 5 is hardly recognized visually under diffused light but emits intense gloss when parallel rays are struck. Consequently, the tile abounding in design, in which a mere delustered tile is viewed according to the striking state of light and a pattern having gloss shines and is embossed on a delustered surface, can be manufactured.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to tiles with patterns, and more particularly to glazed tiles whose patterns appear to stand out when exposed to parallel light.

0002

BACKGROUND OF THE INVENTION Conventionally, tiles with patterns have been produced by drawing a pattern with paint on the surface of a tile base or on a glazed surface of a tile base, and then applying glaze if necessary.

0003

[Problems to be Solved by the Invention] The above conventional tiles are
The pattern is always visually recognized as the same pattern,
The pattern does not change depending on how the light hits it.

The present invention has been made in view of the above-mentioned conventional situation, and an object of the present invention is to provide a tile having excellent decorative properties and a richly designed pattern in which the pattern appears and disappears depending on the condition of the light. .

[0005]

[Means for Solving the Problems] The patterned tile of the present invention is a tile in which a glaze layer is provided on a tile base.
The glaze layer includes a microcrystalline matte glaze layer and a transparent glass glaze of the same color as the matte glaze provided in dots, lines, or partially planar on the surface of the matte glaze layer. It is characterized by becoming.

The present invention will be explained in detail below with reference to the drawings. FIG. 1 is a cross-sectional perspective view schematically showing a tile according to an embodiment of the present invention.

As shown in the figure, the tile 1 of the present invention has a glaze layer 3 provided on a tile base 2, a fine crystalline matte glaze layer 4, and a surface of the matte glaze layer 4 with dots and lines. Or a transparent glass glaze 5 of the same color as the matte glaze, which is partially provided in a planar shape.
It is equipped with the following. "Partially planar" means excluding the case where the entire surface of the tile 1 is coated with transparent glass glaze.

The glaze composition constituting the matte glaze layer 4 is not particularly limited as long as it can provide a fine crystalline surface with a fine matte surface, but generally BaCO3
The blending ratio of (barium carbonate) is relatively large, preferably about 7 to 13% by weight. Incidentally, although the proportion of BaCO3 in a conventional glaze is about 1 to 2% by weight, fine crystallinity cannot be obtained with such an amount of BaCO3.

[0009] Such a matte glaze is used by adding a pigment as necessary.

On the other hand, there are no particular restrictions on the glaze composition for the transparent glass glaze, as long as it forms a transparent glassy glaze layer, but for example, lead-free transparent frit 40 to 100
% by weight and 0 to 60% by weight of zircon.

[0011] The tile of the present invention is made of a normal tile base.
It can be manufactured by applying a matte glaze according to a conventional method, printing a desired pattern on a transparent glass glaze, and firing it. Note that not only a picture but also a pattern made of letters or symbols may be attached.

[0012] After applying the transparent glass glaze, another translucent glaze or the like may be applied, or another pattern may be printed using a translucent glaze. By using such a method, it is possible to manufacture tiles with even more designs.

[0013]

[Function] In the tile of the present invention, among the glaze layers provided on the tile base, the matte glaze layer is finely crystalline and forms a matte surface with poor gloss. On the other hand, the transparent glaze part of the same color as the matte glaze provided on the surface of such a matte glaze is a transparent glassy part of the same color as the matte glaze, so it is hardly visible under diffused light. When exposed to parallel light, it gives off a strong luster.

[0014] For this reason, by putting a pattern on the surface of a matte glaze by combining dots, lines, or planar parts with transparent glass glaze of the same color as the matte glaze, you can change the way the light hits it. As a result, the tiles look like mere matte tiles, or a glossy pattern shines on the matte surface and appears to stand out, making the tiles highly decorative and rich in taste.

[0015]

EXAMPLES The present invention will be explained in more detail with reference to experimental examples and examples below.

Experimental Example 1 A glaze obtained by mixing a metal oxide as a pigment with a matte glaze of the composition shown in Table 1 was applied to a tile base and heated in a roller hearth kiln at 1120°C for 21 to 30 minutes. Fired. The presence or absence of gloss in the glaze layer of the obtained tile was examined, and whether or not the glaze layer was microcrystalline was evaluated based on the following criteria. The results are shown in Table 1. Evaluation Criteria - Matte surface with almost no shine, that is, almost completely fine crystalline. △ A matte surface with relatively little luster, that is, a fine crystalline surface. × Glossy surface, ie, not microcrystalline.

[0017]

[Table 1]

As is clear from Table 1, No. 3-5
In particular, No. Preparation No. 4, ie, one containing about 10% by weight of BaCO3, is suitable as the matte glaze of the present invention.

Example 1 No. 1 of Experimental Example 1 After applying the glaze prepared in step 4 as a matte glaze to a tile base, a pattern was printed with a transparent glass glaze of the same color as the matte glaze, which was composed of 90% by weight of lead-free transparent frit and 10% by weight of zircon. Furthermore, No. Zircon was removed from the formulation in step 4 to create a translucent glaze, which was applied in the form of a mist. Thereafter, it was fired under the same conditions as in Experimental Example 1.

As a result, under diffused light, a blurred pattern due to the mist-like translucent glaze can be seen, and when exposed to parallel light,
A tile with a transparent glass glaze pattern emerging from beneath the blurred pattern was obtained.

Example 2 In Example 1, No. The same procedure was carried out except that zircon was removed from the preparation of 4 and the glaze was applied dropwise (bottomed) to form a translucent glaze.

As a result, a tile was obtained in which a pattern made of transparent glaze applied in droplets was visible under diffused light, and when exposed to parallel light, a pattern made of transparent glass glaze stood out from beneath the pattern.

Example 3 In Example 1, after printing a pattern with the glass glaze, a transparent glass glaze of the same color as the matte glaze consisting of 20% by weight of leaded frit, 20% by weight of lead-free transparent frit, and 60% by weight of zircon was applied. Another pattern was printed using , and then fired in the same way.

As a result, under diffused light, only the upper pattern is slightly visible, and when parallel light is applied, the upper pattern may stand out clearly depending on how it hits the object, or milky white or transparent glass may appear from below the upper pattern. Tiles with glazed patterns that stand out were obtained.

[0025]

As described in detail above, according to the patterned tile of the present invention, a tile with excellent decorativeness and rich taste is provided in which the pattern appears or disappears depending on the lighting conditions.
