Manufactured from high quality black granite, quarried in California. This material has been carefully evaluated to assure a high modulus of elasticity, complying with federal specifications and user requirements. Government tests have shown that fine-grained black granites are stronger, denser and less absorptive than other granites. The superior stiffness of black granites is highly desirable for surfaces where accuracy and stability are essential.
