The present invention discloses a simulated limestone, a method of producing the simulated limestone, and a method of achieving a surface texture. The simulated limestone has been specifically formulated and designed in order to overcome the currently existing problems of other simulated or artificial stones that are currently available. The invention additionally discloses a method of producing the simulated limestone which provides unique characteristics. Also disclosed, is a method of preparing a surface texture which provides a product having the enhanced appearance of natural limestone. Both methods disclosed herein may be completed in a time efficient manner and produce a simulated limestone having the appearance of natural limestone and other benefits described herein.

1. A simulated limestone, comprising: from about 30% w/w to about 40% w/w of a base polyester resin; from about 10% w/w to about 20% w/w of an alumina trihydrate; from about 5% w/w to about 15% w/w of a microsphere; from about 10% w/w to about 20% w/w of a sand; from about 0.5% w/w to
1. A simulated limestone, comprising: from about 30% w/w to about 40% w/w of a base polyester resin; from about 10% w/w to about 20% w/w of an alumina trihydrate; from about 5% w/w to about 15% w/w of a microsphere; from about 10% w/w to about 20% w/w of a sand; from about 0.5% w/w to about 7% w/w of a pigment; and from about 0.9% w/w to about 1.25% w/w of a catalyst. 2. The simulated limestone of claim 1, wherein the simulated limestone has the appearance of natural limestone.3. The simulated limestone of claim 1, wherein the simulated limestone has a weight of about less than 50% of an identically sized natural limestone.4. The simulated limestone of claim 1, wherein the simulated limestone has a weight of about less than 40% of identical precast concrete.5. The simulated limestone of claim 1, wherein the simulated limestone is capable of resisting damage by ultraviolet light, extreme temperatures, fire, water, and most acids.6. The simulated limestone of claim 1, wherein the simulated limestone does not shrink after exotherm cure is complete.7. The simulated limestone of claim 1, wherein the simulated limestone is resistant to damage by an impact of up to 0.45 ft-lb/in.8. The simulated limestone of claim 1, wherein the simulated limestone has a coefficient of linear thermal expansion of about 3.8×10−5per degree Celsius.9. An artificial limestone, comprising: about 40.82% w/w of a base polyester resin; about 13.61% w/w of an alumina trihydrate; about 16.33% w/w of a microsphere; about 27.21% w/w of a sand; about 1.63% w/w of a pigment; and about 0.41% w/w of Methyl-Ethyl Ketone Peroxide. 10. The artificial limestone of claim 9, wherein the artificial limestone has the appearance of natural limestone.11. The artificial limestone of claim 9, wherein the artificial limestone has a weight of about less than 50% of an identically sized natural limestone.12. The artificial limestone of claim 9, wherein the artificial limestone has a weight of about less than 40% of identical pre-cast concrete.13. The artificial limestone of claim 9, wherein the artificial limestone is capable of resisting damage by ultraviolet light, extreme temperatures, fire, water, and most acids.14. The artificial limestone of claim 9, wherein the artificial limestone does not shrink after exotherm cure is complete.15. The artificial limestone of claim 9, wherein the artificial limestone is resistant to damage by an impact of up to 0.45 ft-lb/in.16. The artificial limestone of claim 9, wherein the artificial limestone has a coefficient of linear thermal expansion of about 3.8×10−5per degree Celsius.17. A method of producing a simulated stone, comprising: providing a mold; and pouring into the mold a simulated limestone material comprising: from about 30% w/w to about 40% w/w of a base polyester resin;from about 10% w/w to about 20% w/w of an alumina trihydrate;from about 5% w/w to about 15% w/w of a microsphere;from about 10% w/w to about 20% w/w of a sand;from about 0.5% w/w to about 7% w/w of a pigment; andfrom about 0.9% w/w to about 1.25% w/w of a catalyst.18. The method of claim 17, wherein pouring into the mold the simulated stone material further comprises pouring the simulated stone material into the mold within from about 5 minutes to about 7 minutes of adding the catalyst to the base polyester resin, the alumina trihydrate, the microsphere, the sand, and the pigment.19. A method of achieving a surface texture, comprising: machining a foam material into a desired shape so that a male model is formed; providing a container having a bottom surface, the container being capable of holding a polyurethane rubber material; placing the male model on the bottom surface of the container; pouring the polyurethane rubber material into the container so that the polyurethane rubber material hardens to form a female mold; and pouring into the female mold a simulated stone material comprising: fro m about 30% w/w to about 40% w/w of a base polyester resin;from about 10% w/w to about 20% w/w of an alumina trihydrate;from about 5% w/w to about 15% w/w of a microsphere;from about 10% w/w to about 20% w/w of a sand;from about 0.5% w/w to about 7% w/w of a pigment; andfrom about 0.9% w/w to about 1.25% w/w of a catalyst.20.
