However in my opinion some of the hardest and strongest rocks in the world are the quartzites found in the Witwatersrand in South Africa, Quartzite is a sandstone which has metamorphosed-that is it has been subject to high pressures and temperatures which have modified its structure.
What is the most dense material known to man? The densest known material is the Element Osmium, at about 22 tonnes per cubic meter. The densest theorized material would be white dwarf/neutron star matter, which could be m â¦ illions of times denser. Of course, since it occupies no space at all, the density of a black hole's singularity is technically infinite.
