The artificial natural stone is prepared by (A) sculpturing a desired shape in a lime stone with irregular piled layer, (B) immersing the sculptured stone in 15-20% hydrochloric acid containing aqueous solution for 5 hours, and (C) grinding the processed stones by rotating the rotational cylinder with sand, water and the stones at 20 RPM for 1 hour. This method can change the lime stone into natural shaped stone. So it can be used for orchid graftage, pot-planting and fishing port viewing.
