Lucas cited many references to show that quartz sand could drill granite However none of these references indicated that concentric lines were formed as a result of the drilling Petrie speculated that diamond and corundum were used for drilling He rejected diamond for its rarity and corundum for its impossibility in favor of
Particle mesh size is the number of holes in a 1" square screen As the mesh number gets larger the number of holes per inch increases the size of each individual hole decreases and the media becomes finer Grit refers to coarseness; the lower the number the coarser the Steel Grit — Leaves a textured surface to enhance the bonding ability of paint and other coatings
