Quartz countertops are made by man, but are not synthetic since they are chiefly particles of natural quartz aggregate held together and colored with seven percent or less of other substanc Also called engineered quartz, the countertop slab is actually made of this mixture which is pressed into slabs, which are hardened by baking and cooling.

Fused quartz is prone to phosphorescence and "solarisation" (purplish discoloration) under intense UV illumination, as is often seen in flashtub "UV grade" synthetic fused silica (sold under various tradenames including "HPFS", "Spectrosil", and "Suprasil") has a very low metallic impurity content making it transparent deeper into the ultraviolet.

Quartzite Characteristics Quartzite registers as a 7 on the Mohs hardness scale Quartzite can be found in varying shades of red and tinges of pink because of iron oxide that becomes mixed in with the sandstone Other impurities can make their way in to the mix causing various color changes but most quartzite is found as a white to grey color.
