Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a patterning method for natural stone-like tiles that brings out the texture of natural stone.

Conventional technology Conventionally, tiles were either fired or applied as they were or were fired by applying a single glaze, but in either case, a heavy atmosphere or high-class feeling could not be expressed, and recently Tiles are becoming more and more important not only in their uses and effects, but also in their visual sense, and there are limits to the current manufacturing methods.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the present invention, the surface of a tile is made to have a shade or a change in hue of a plurality of colors, and an uneven pattern of a polished portion and an unpolished portion is formed to reveal the texture of natural stone. It is intended to provide a patterning method for such natural stone tiles.

[Structure of Invention]

Means for Solving the Problems In view of the problem that the tile surface is single and does not have a high-class feeling, which is based on the conventional technique, the present invention applies two or more layers of glazes having different melting degrees to the surface of the tile and fires them. The uneven surface of the glaze layer after firing is polished so that the unpolished portion of the valley portion remains, so that the texture of natural stone is revealed and the above drawbacks cannot be solved.

Working The present invention forms two or more uneven glaze layers having different melting degrees, and randomly mixes the hard glaze and the soft glaze by firing, and surrounds the hard glaze with the soft glaze, By polishing the surface of the glaze layer so that the unpolished portion remains, and polishing so that the hard and soft glaze appears on the surface, the polished surface becomes the hard and soft glaze portion and the unpolished portion, and in the glaze portion Light and shade may occur or a change in the hue of multiple colors may occur, and a concavo-convex pattern may occur between the polished part and the unpolished part.
The texture of natural stone occurs due to the action of both.

EXAMPLE An example of the present invention will be described below with reference to the drawings. The glazes 2 and 2a having different melting degrees of three layers (the number of layers is not limited) are glazed on the surface of the tile 1 so that irregularities are generated. The calcined glaze layer is calcined from the top of the surface by a proper thickness and by a suitable method. At this time, the peaks and depressions of the glaze layer are polished parts 3, 3a, and the troughs are unpolished parts 4, 4a. To be polished.

When the glaze layer is fired, the soft glazes 2, 2a ... are melted first, so that the hard and soft glazes 2, 2a are randomly mixed, or the soft glazes 2, 2a are surrounded by the soft glazes 2, 2a.
… Penetrates and surrounds.

At the time of polishing, polishing is performed so as to cut a random hard and soft glaze layer, and in the abraded parts 3, 3a ..., different shades or different colors are generated due to different types of glazes 2, 2a .. Differently, further, the polished portions 3, 3a ... And the unpolished portions 4, 4a .. Appear and an uneven pattern is generated, and the texture of natural stone is generated on the surface of the tile 1 by the action of both of them.

It should be noted that the surface of the tile 1 may be roughened before the glaze and before the firing.

〔The invention's effect〕

In short, according to the present invention, two or more layers of glazes 2, 2a having different degrees of melting are glazed and fired on the surface of the tile 1, and the uneven surface in the glaze layer after firing is used to form the unpolished portions 4, 4a in the valleys. …
I made it so that it would remain so that it was hard and soft glaze 2.
2a ... are mixed and polished, a complex pattern of light or shade appears on the entire surface of the tile 1, and the polished portions 3, 3a
... and the unpolished portions 4, 4a ... reveal an uneven pattern, and the specular reflection portions of the polished portions 3, 3a ... And the unpolished portions 4, 4a.
The mixed effect of the irregular reflection portions causes the different textures of natural stones to appear for each tile 1 due to the action of the two.
