PURPOSE: A manufacturing method of artificial marble having amorphous pattern is provided to manufacture artificial marble having reproducibility and diversity of amorphous pattern without additional facility by using mixture of two kinds of different specific gravity of artificial marble. CONSTITUTION: An artificial marble having amorphous pattern comprises color component and base component. The color component is formed with mixture for low ratio of artificial marble, and the base component is formed with mixture for high ratio of artificial marble. The artificial marble has amorphous pattern at the top surface, bottom surface, side, and inside. The specific gravity difference between color component and base component is 0.18 - 0.60. A manufacturing method of artificial marble having amorphous pattern comprises the following steps. (a) The mixture for low ratio of artificial marble is sprayed on the molding cell or the endless steel belt as an amorphous pattern. (b) The mixture for high ratio of artificial marble is coated with the mixture for low ratio of artificial marble. And (c) the two mixture are solidified together by moving the mixture for low ratio of artificial marble to the top portion through inside the mixture for high ration of artificial marble.
