Unnatural Formation. In spite of the vast amount of naturally occurring quartz, most quartz used for industrial purposes is man-made. A heat treatment can be used to synthesize various types of quartz, especially by the use of high pressure and temperature in water.

The basic structural element of silica is the SiO 4 tetrahedron.Quartz consists of interconnected SiO 4 tetrahedra that build up a rigid three-dimensional network (discussed in detail in the chapter Quartz Structure).There are many possible ways of connecting SiO 4 tetrahedra different from that found in quartz, realized in various other silica polymorphs.

The Paroscientific design uses a quartz crystal operating in flexure mode to measure force. To derive a pressure output, a force-summing device such as a Bourdon tube or bellows must be used. Thus, the transducer senses pressure through the force-summing device and .
