い不定形の模様に対するニーズが高まっている。BACKGROUND OF THE INVENTION In recent years, preferences for the surface patterns of tiles installed on the interior and exterior walls of buildings have diversified, and there has been a growing need for extremely unique irregular patterns.

である。SUMMARY OF THE INVENTION In order to meet these needs, the present invention provides a method for producing an irregular pattern on a ceramic product, which is completely different from conventional surface patterns.

することを特徴とする。[Means for Solving the Problems] The present invention provides a glaze composition,
Alternatively, granules made of raw materials to which various inorganic materials have been added are flattened, and the flattened granulated raw materials or those coated with pigments are laminated on the base of ceramic products, and this is processed. It is characterized in that the surface is polished after being pressed and fired.
【0006】偏平化した造粒原料の含水率が低いと素地
との密着性が悪く、また高いと形成された模様が流れや
すく、また素地材料が成形型に付着しやすく脱型しにく
く、生産性が低下する。したがって、積層時の偏平造粒
物の含水率は5〜10%、好ましくは7〜8%がよい。[0006] If the moisture content of the flattened granulated raw material is low, the adhesion with the base material is poor, and if it is high, the formed pattern tends to flow, and the base material tends to adhere to the mold, making it difficult to remove from the mold, resulting in production problems. Sexuality decreases. Therefore, the moisture content of the flat granules during lamination is preferably 5 to 10%, preferably 7 to 8%.
【0007】この積層物の加圧は、加圧力が低すぎると
偏平粒がつぶれにくく、また素地との密着性と充填率も
充分ではなく焼成後発泡状態になる。また、高すぎると
水分移動により造粒物が変形し模様が流れる傾向がある
。その適用される加圧力は200〜400kg/cm2

1300℃がよい。 さ
らに、偏平化した造粒物の長さは任意のものが使用でき
るが、タイルにおいては5〜20mm長さのものが成形
上からも、又形成された模様からも都合がよい。If the pressure applied to this laminate is too low, the flat grains will not be easily crushed, and the adhesion to the substrate and filling rate will not be sufficient, resulting in a foamed state after firing. Furthermore, if the temperature is too high, the granules will be deformed due to moisture movement and the pattern will tend to flow. The applied pressure is 200~400kg/cm2
It is good to be. Firing temperature is usually 1200~
1300°C is good. Further, any length of the flattened granules can be used, but for tiles, a length of 5 to 20 mm is convenient from the standpoint of molding and the pattern formed.

This creates a unique pattern that is not found in conventional ceramic products, with a complex mix of large and small outlines. In addition, when the granulation raw material is coated with pigment, after surface polishing,
The outline of the pattern that appears can be made clearer. By adjusting the particle size distribution and pigment composition of the flat granules, the color distribution, outline width, size, etc. of the pattern that appears can be controlled as desired.

Parts by weight of the inorganic raw material were wet-pulverized in a ball mill and granulated. At this time, a coloring material may be kneaded to form colored granules. For example, when coloring white, the white pigment base material (Fe2 O3
0.2% or less). The granules were formed into a cake using a filter press and dried to a moisture content of 10 to 15%. After drying, it was granulated using an Eirich mixer to a size of about 2 to 10 mm, and the granulated product was rolled with a roller to obtain flat granules with a length of 5 to 20 mm. After this, reduce the moisture content to 7
It was adjusted to ~8%. Next, the flat grains were coated with pigment. This flat granulated material was laminated on top of the tile material. In this case, the base material for the tile material is granulated in advance to a diameter of 0.3 to 1.0 mm using a spray dryer. Figure 1 shows an overview of the equipment used for lamination. In the figure, reference numeral 1 indicates a 300 mm square tile material placed on a lower mold 3 in a formwork 2. The flat granules prepared as described above were laminated on this tile material 1 to a thickness of approximately 5 mm. The upper mold 5 was pressed onto the laminate 4 at a pressure of 300 kg/cm 2 to form the mold. This molded body was fired at 1300° C. for 1 hour in a roller hearth kiln. The surface of this fired product was polished to a thickness of approximately 0.5 mm using a polishing machine.
