。この大模様の形成には、模様型表面に消泡剤を塗布し
ておく方法が知られてもいる。For such inorganic plates, from the viewpoint of improving the surface design, attempts have been made to form patterns on the surface by cutting as well as to form large patterns. A known method for forming this large pattern is to apply an antifoaming agent to the surface of the pattern.
（発明が解決しようとする課題）
しかしながら、このような従来の模様型表面への消泡剤

効な方法ではなかった。(Problem to be Solved by the Invention) However, in this conventional method of defoaming the air bubbles near the mold by applying an antifoaming agent to the surface of the pattern mold and forming a large pattern using this method, it is difficult to prevent the air bubbles from forming on the inorganic plate. Although this method is effective in cases such as aerated concrete plates that have residual air bubbles inside, it has not been very effective for ordinary concrete-based inorganic plates with a small amount of air bubbles mixed in.
このため、通常の無機質板の場合にも大模様の形成が容

いる。This invention was made in view of the above circumstances, and aims to improve the shortcomings of the conventional method of forming large patterns, and to easily form large patterns on the surface even on ordinary inorganic boards with few air bubbles. The purpose is to provide a method for doing so.

This hole becomes the pattern. The pattern of holes on the surface can be changed depending on the method of dispersing the aluminum powder, the size of the particles, the amount of cement mixed in the slurry, etc. For example, random hole patterns with good design can be easily formed by randomly scattering aluminum powder.
