It is important to differentiate between fused quartz and fused silica, often confused as the same. MGS is a custom fabricator of quartz, silica, borosilicate.
But while quartz crystals continue to be used for fused quartz, it has been found that when crystalline silica occurs in sand or rock, it can also produce fused quartz, or synthetic fused silica, as this man-made fused quartz is sometimes called.
To most of us, the desert sands would have as much to do with the modem technology we use every day as dinosaurs with fast food. Yet sand is now the basic material used to create fused quartz. This process begins by melting natural quartz crystals present in quartzite sand, and then cooling it to produce an amorphous substance, also known as quartz glass. This process is carried out in vacuum in order to prevent inclusion, ripple and bubble formation in the viscous melt. The temperature at which the melt is processed is 1900 degrees centigrade. The chemical composition of fused quartz is the same as that of fused silica, and its chemical representation is Si02, or, Silicon dioxide.
