The sand can be packed by hand, but machines that use pressure or impact ensure even packing of the sand and require far less time, thus increasing the production rate. After the sand has been packed and the pattern is removed, a cavity will remain that forms the external shape of the casting.

Silica sand provides the essential Silicon Dioxide (SiO2) required for glass formulation, which makes silica the primary component in all types of standard and specialty glass. Though the production of glass requires a variety of different commodities, silica represents over 70% of its final weight.

Sand castings are less common in structural applications, due to their slower cooling rate and generally coarser microstructure. However, in certain applications, such as the cast 356-T6 nodes for the Ford GT spaceframe, need for specific geometries at low production volumes requires the use of sand castings.

Isolating silicon from silica is the first step in the production of silicone. This is done by heating a large volume of quartz sand to temperatures as high as 1800˚C. The result is pure, isolated silicon, which is allowed to cool and then ground into a fine powder. To make silicone, this fine silicon powder is combined with methyl chloride
