使い捨てであって不経済であり且つ資源を無駄に浪費す
る、という別の問題点がある。When a drink in a glass or a bottle is cold, water droplets are generated on the outer surface of the glass or the like, and the water droplets hang down and collect on the coaster. However, conventional coasters have almost no water absorption, so there are many cases where water drops on the bottom of a cup or the like drip and wet the table or clothes. Wipe the bottom of the cup with a hand squeezer (towel) close at hand. The sight of drinking water while drinking water is not unusual. Also, if you casually lift a cup or the like casually, the coaster may rise together with the work of the water accumulated at the bottom, it is late to notice it, and it is uncomfortable, or you are surprised by the gleaming falling sound of the coaster There was such a problem. In addition, when the coaster is made of paper, although it has water absorption for a while and does not have the above-mentioned problems at first, the water absorption performance is too low with thick paper, so that the water cannot be absorbed immediately. Occurs. In addition, paper coasters have the additional problem that they are almost disposable, uneconomical and waste resources.

い。The coaster 1 manufactured as described above
Is porous because there is a gap between the powders of the ceramic raw material and it is porous. Very good. Since the ground of the pottery is exposed on the upper surface 7, water drops dripping from the cup A and the like are absorbed and absorbed, so that water does not collect on the upper surface 7 of the coaster 1. In an experiment using a prototype (diameter = 87 mm, thickness = 5 mm), a water absorption capacity of about 30 cc was confirmed at a time. However, in actual use, water soaked in spreads widely on the upper surface of the coaster 1 and evaporates. Has the above water absorption capacity. Further, since the bottom surface 2 has a protective layer 3 made of glaze and is smooth, the surface of a table or the like is not damaged.

き、従って、発色のよい文字等8が描ける。When it is necessary to draw characters or figures (hereinafter referred to as characters, etc.) such as store names on the upper surface 7 of the coaster 1 as shown in FIG. 4, for example, a pigment of water-resistant ink is attached to the particles of the ceramic. It is good to do so. That is,
Characters 8 are printed on the upper surface 7 of the coaster 1 by a method such as stamp printing using the pigment dissolved in the oil, and the pigment is dried as it is to leave only the pigment. By doing so, characters 8 can be drawn without lowering the water absorption performance of the coaster 1. As another method, characters 8 may be represented by fine dots using existing transfer paper. In this case, since water permeates the coaster 1 through the mesh of dots, it is possible to use even existing pigments for ceramics that impede the passage of water, and thus it is possible to draw characters 8 with good color development. .

If the through-hole 9 is present, even if water drops exceeding the water absorption capacity of the coaster 1 drop from the cup A or the like, the water is removed from the through-hole 9 and air enters, so that the coaster 1 and the cup A do not adsorb. . Of course, the number of the through holes 9 does not need to be one, and
The location of the through hole 9 may be any location as long as it is within the mounting area where the cup A and the like are placed.

その粉を焼成により消失させる方法がある。Although the present invention has been described with reference to the embodiment, the present invention is not limited to the above embodiment. For example, in the embodiment, the coaster 1 is made of ceramic, but may be made of porcelain if it is porous. In general, porcelain has a lower water absorption than porcelain and is unsuitable for the coaster 1 of the present invention. For example, porcelain bowls are finely crushed into powder, and the powder and porcelain raw material having a lower melting point than the powder are used. May be mixed, and the porcelain powder may be fused together using a low melting point ceramic material as a binder. This means implements a technical idea that "a ceramic raw material is a mixture of two or more powdery raw materials having different melting points, and a high melting powdery raw material is welded with a low melting powdery raw material." It is a form. As a means for making the ceramic porous, there are a method of unglazing and a method of mixing an organic powder with the ceramic raw material and eliminating the powder by firing.

コップ等が滑らず安定性がよい。According to the coaster of the present invention, since the ground of the ceramic is exposed at least on all or a part of the upper surface, water drops falling along the cup or the like are absorbed into the ceramic. Therefore, it is possible to prevent the bottom of the cup or the like from being soaked with water, and to prevent the table or clothes from getting wet with water or sticking the coaster to the bottom of the cup or the like. In addition, because the ground of the ceramics is exposed on the upper surface of the coaster and there is roughness,
Good stability without slipping cups.

い、などの効果がある。According to a third aspect of the present invention, there is provided a manufacturing method in which a powdery ceramic material is put into a mold, press-molded, and at least all or a part of the upper surface of the compacted product is unglazed and fired. According to this, it is possible to provide a coaster that is more porous and excellent in water absorption than a conventional product obtained by solidifying and firing a ceramic material (clay) kneaded with water, such as a bowl. In addition, since there is almost no warpage or distortion in the firing step as compared with the above-mentioned conventional manufacturing method, there is an effect that there is no problem that rattling occurs during use.
