PURPOSE: To manufacture the title stone easily by making a calcinating process unnecessary and prevent generation of powdering or whitening, by a method wherein a composition for manufacturing artificial stone containing a mixing agent for cement, water, aggregate and the cement and a material having light- transmission properties are mixed with each other and the light-transmission material is extended thicknesswise.
CONSTITUTION: In the case where a weight of a mixing agent is made 100%, calcium chloride, natural or synthetic rubber, resin, water and an organic solvent are made respectively 20W40wt.%, 0W25wt.%, 10W25wt.%, 20W40wt.% and 10W20wt.%, in the mixing agent for cement. A composition 3 for manufacturing normal artificial stone is obtained by adding the mixing agent for cement to a mixture of water and aggregate by diluting the mixing agent for cement by about 10W20 times with water. Fluorite 2 having light-transmission properties is put on an appropriate position within a mold 1 by raising the same depthwise, into which the above composition 3 is cast and after defoaming by vibrating the mold natural curing is performed. When polishing or grinding is performed at a part shown by imaginary lines 4, 5 by performing demold, inlaylike artificial stone is obtained.
