Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ...
The Egyptian workers simply dribbled quartz sand beneath the copper saws and drills. This abrasive is harder than the mica and feldspar components of granite but not the quartz. Nevertheless, granite will yield slowly to the abrasive, as do the copper tools themselves. In 1999, Stocks tested the efficacy of copper saws and drills on the ...
