PURPOSE: To obtain a material having a stone-like appearance visible surface by preparing a translucent medium fine piece for forming an outer surface, filling a second type fine particle material in a space in adjacent contact with its inner surface, fixing it with a first type material, and evacuating air from an area near the inner surface.

CONSTITUTION: As a translucent medium, in the case of a hard material, a transparent glass or hard transparent plastic material is used. Or in the case of hard material, surface is sprayed and then cured plastic material is used. A first type material has properties as a filler, and is operated as an adhesive of a liquid to be cured to solid or semi-solid. A second type material of cut and comminuted to independent fine pieces, and cut chips of wood, sheet, woven fabric, shell, sand or the like is used. Surfaces of the second type material of the medium is coated with the first type material of adhesive filler, covered with a layer of the second type material, and pressed to the layer of the adhesive filler. Then, the filler is cured to eliminate air gap between the pieces and between the cut material and the medium. Thus, an effect of a polished stone or marble can be created.
