る。Examples of the porcelain slurry for surface patterning include those containing pigments for forming patterns of various colors, and those containing fillers for forming patterns such as natural stones. When using a slurry containing a filler, if the filler used is of the same ceramic base material as the ceramic slurry for surface patterning, the filler and the matrix (matrix) matrix show almost the same firing shrinkage, so that cracking occurs. Is less likely to occur. Examples of the method for producing the ceramic base material filler include a method in which a ceramic base material slurry to which a binder and a pigment are added is dried, then crushed and sieved, or formed into granules by a spray dryer method or the like. .

ものを用いても良い。In addition, as the ceramic slurry for the molded article main body, normal casting slurry can be used, but for a product having a drilling step or a cutting step, a cross section in the filling direction is exposed, and there is a pattern of a surface layer. The part and the part without the pattern of the inner layer constituting the molded article main body become unnaturally discontinuous, which may be inconvenient in appearance. In such a case, the same as the ceramic slurry for forming the surface pattern may be used as the ceramic slurry for the molded article body.

研磨が容易である。In addition, when the smoothness of the surface of the molded article after demolding is not sufficient, the surface of the molded article can be polished after drying. In particular, when the ceramic slurry for surface patterning contains a filler, the filler may not sufficiently come out of the surface or the filler portion may protrude from the application surface depending on the viscosity of the slurry and the amount of the filler. In such a case, it is necessary to polish the surface after drying to expose the filler or to smooth the surface. In this case, if the filler is made of a ceramic body, polishing is easy.

されて移動しなくなる。(Operation) According to the first method, the ceramic slurry for surface patterning is used for the separation and separation of the pattern generated when the viscosity is low, without the time when the casting stripes of the slurry generated when the viscosity is high are generated. Shortly after the displacement occurs, the lower mold is inlaid and the pattern on the mold surface is fixed and does not move.
第２の方法によれば、表面模様出しのための陶磁器泥
漿をガンにより吹き付けるので、複雑な形状であっても
表面模様出しのための陶磁器泥漿は型表面に均一な厚さ
で固着される。According to the second method, since the ceramic slurry for surface patterning is sprayed by a gun, the ceramic slurry for surface patterning is fixed to the mold surface with a uniform thickness even in a complicated shape.
