2. Description of the Related Art Generally, artificial marble is obtained by heating and polymerizing a mixture of 100 parts by weight of an artificial marble syrup and about 100 parts by weight of an inorganic fine powder such as silica or calcium carbonate. The specific gravity of the inorganic fine powder is about 2.5, while the specific gravity of the marble syrup is about 1 g / cm 3 .
g / cm 3 , the specific gravity of the obtained artificial marble is also large and heavy at about 1.8 g / cm 3. For example, when the artificial marble is used for a countertop or a bathtub, the weight is 1%.
There is a drawback that the load becomes very heavy, about 40 to 60 kg per unit, and that the load on a person in the mounting work or the like is large.

Therefore, in order to reduce the weight of artificial marble, it is conceivable to use, for example, an inorganic expanded granular material having a small specific gravity in place of the inorganic fine powder. However, since the specific gravity is small as compared with the specific gravity of the artificial marble syrup. Separation occurred in the composition, and it was not possible to obtain artificial marble in which the inorganic foamed granules were uniformly dispersed.
