A method of using natural crushed marble, aluminum hydroxide, etc. as an aggregate, compounding this with a polyester resin to prepare a compound, and integrally molding this compound and a reinforcing material such as flat lath to obtain artificial marble Are known. However, since polyester resin is usually used as a binder for the aggregate in the above-mentioned manufacturing method, flammable polyester may be included more than necessary depending on the type and amount of the aggregate, and the compounding conditions for obtaining quasi-incombustible properties are limited. In addition, if the aggregate and the polyester resin are not mixed uniformly, the adhesion with the reinforcing material is poor, and cracks are likely to occur when the obtained artificial marble is heated.
