ABSTRACT:
An artificial marble using transparent chips, and a process for preparing the same, in which transparent chips are prepared by crushing a flat plate made of a composite for the artificial marble, which does not contain an inorganic filler and thus maintains transparency, quartz chips are prepared by crushing a flat plate made of a mixture of the transparent chips and a composite for the artificial marble, which contains an inorganic filler, for uniforming the specific gravity of the quartz chips, and the artificial marble is prepared by applying the quartz chips to a raw material composite for the artificial marble, thereby allowing the artificial marble to have the uniform specific gravity and exhibit a quartz effect.
