An engineered stone includes a light transmitting mother material (I) and a phosphorescent chip (II). The light transmitting mother material (I) includes about 7 wt % to about 12 wt % of an unsaturated polyester resin (A), about 88 wt % to about 93 wt % of a silica-containing compound (B) and about 0.01 part by weight to about 1 part by weight of an organic/inorganic pigment (C) based on about 100 parts by weight of the unsaturated polyester resin (A). The phosphorescent chip (II) includes about 8 wt % to about 15 wt % of an unsaturated polyester resin (A'), about 85 wt % to about 92 wt % of a silica-containing compound (B&#x2032;) and about 2 parts by weight to about 10 parts by weight of a phosphorescent pigment (D) based on about 100 parts by weight of the unsaturated polyester resin (A&#x2032;).

Engineered stone and manufacturing method thereof

Provided are a chip with a stereoscopic texture for a resin-based reinforced natural stone and a resin-based reinforced natural stone including the same. A chip with a stereoscopic texture can be obtained by coating a pigment on a surface of a crushed reinforced natural stone chip. In a resin-based reinforced natural stone to which the chip with a stereoscopic texture is added, a boundary surface between the chip and a matrix is formed, such that a texture of natural stone and a three-dimensional stereoscopic effect may be implemented, thereby making it possible to implement an aesthetically beautiful surface.

An artificial silica marble comprises a matrix and a line pattern portion. The line pattern portion comprises fine lines having a width of about 50 to about 500 &#x3bc;m and forms a web- or net-like pattern. The line pattern portion divides or partitions the artificial silica marble into a plurality of irregularly shaped pattern portions to form an amorphous pattern in the cross section of the artificial silica marble.

An artificial marble includes unsaturated polyester resin (A), compound including silica (B), and luminescent pigment (C). An artificial marble according to a second embodiment includes about 70 to about 95% by weight of a non-luminescent base material (I) comprising unsaturated polyester resin (A), compound including silica (B), and organic/inorganic pigment (C) and about 5 to about 30% by weight of a luminescent amorphous pattern part (II) comprising unsaturated polyester resin (A), compound including silica (B), and luminescent pigment (D). An artificial marble according to a third embodiment includes unsaturated polyester resin (A), compound including silica (B), and amorphous luminescent chip (C).
